They're beautiful, they're close to home, and they're steeped in history. But the best reason to vacation in one of our 6,624 state parks? They're fast becoming an endangered species.

California's Mono Lake Tufa State Natural Reserve has made big news twice in the past two years. The first time came in December 2010, when scientists thought they'd discovered an unusual form of bacteria that devoured arsenic while it lurked in the mud around the lake's knobby limestone spires. But it was the second headline, five months later, that was really scary. That was when California's state parks department announced that Mono Lake itself was about to be wiped out--though by a far more mundane force.

Mono was one of 70 parks targeted by the state in an effort to cut $22 million from California's budget gap, which totaled $9.2 billion at the time. Also on the list: Jack London's former home and writing studio in Sonoma County and a handful of old-growth redwood forests along the northern coast. All told, California was talking about mothballing about 25 percent of its 278 parks. The news hasn't been much better elsewhere. New York, Illinois, Colorado, Arizona, Nevada, Virginia, and Idaho have contemplated closing parks in recent years; Ohio has considered leasing some state park lands for oil and gas drilling to help raise money; and Virginia has explored corporate partnerships to keep park gates open.

What gets lost in this game of budgetary Russian roulette is how precious these lands can be. State parks, such as the ones you'll see here, often rival their national-park cousins in sheer beauty: Did you know that Niagara Falls is actually a New York state park? Last year, the nation's 6,624 state parks attracted 720 million visitors, more than twice what the national parks see, and they do it with almost $1 billion less in annual operating revenue. "Some states have had cuts of 30, 40, 50 percent or more in their operating budgets, and some budgets have been cut twice in one year," says Rich Dolesh, the vice president for conservation and parks at the National Recreation and Park Association.

More On This...

Yet, true to their more-with-less ethos, state parks are finding imaginative ways to hang on. Michigan has seen some success selling annual passes to its parks system, and other states have made arrangements with communities and nonprofits to share the financial burden-at least for a while. In April 2012, New York Governor Andrew Cuomo pledged $89 million for repairs and improvements to his state's parks. As for California: As of press time, 65 of the 70 endangered parks had been temporarily spared-including Mono Lake-thanks to help from the communities that depend on them. They've cobbled together private donations, volunteer staffing, and funding by city and county governments and nonprofits to try to bridge the gaps. We may not be out of the woods yet, but we're certainly sniffing out the trail.

Mono Lake Tufa State Natural Reserve

California

This park's namesake tufa towers, limestone formations that rise from its 65-square-mile lake, are impressive from wherever you're standing. But to fully apprecate them, you've got to approach like an osprey might: coming in low over the water. Can't fly? Then bring a canoe. Up close, the spires resemble white-chalk skyscrapers, a kind of surreal city that's visited by more than a million migratory birds each year. Just don't get too close to the ospreys themselves. From April through August, the birds nest on the towers, and it's forbidden to come within 200 yards.

Like anything else this old-the lake has been around for anywhere from 760,000 to 3 million years-Mono Lake endured its share of woe long before the latest California budget struggle. Between 1941 and 1981, Mono lost half its volume and doubled in salinity after four of its five tributaries were diverted to supplement Los Angeles's water supply. Even now, it's almost three times as salty as the ocean. Yet, thanks to the Mono Lake Committee, which rallied to reclaim those lost streams in 1978, the lake is slowly filling up again. And now that the nonprofit Bodie Foundation has stepped in to help keep Mono Lake open to the public, you'll be able to witness the lake's gradual climb back to a healthy level-however long that takes. Let's hope we can say the same for the rest of California's parks.

Where to Stay: There's no camping at Mono Lake, but you'll find a range of accommodations in Mammoth Lakes, a ski town 40 miles south. The pet-friendly Mammoth Creek Inn Hotel and Spa has a new spa and fitness center and 26 renovated rooms (themammothcreek.com, doubles from $109).

While You're There: You can't very well travel to Mono Lake and not tack on a visit to Yosemite National Park, just 13 miles west. Although, with nearly 12,000 square miles to explore, you'll need more than a brief detour to tackle it all (nps.gov, admission $20 per car).

How to Help: Make a donation to the Bodie Foundation, specifying that you'd like the money to go toward Mono Lake (bodiefoundation.org).

Park Info: 1 Visitor Center Drive, Lee Vining, Calif., 760/647-6331, parks.ca.gov, hours vary (call the park in advance to check), admission free, parking $3

Niagara Falls State Park

New York

Niagara Falls has an image problem. Really. Start with the fact that almost no one knows that this crown jewel of the state park system is a state park-not to mention that, at 127 years old, it's also the nation's oldest. The American side has long played second fiddle to the casino-and-hotel-lined Canadian section, due in part to New York State's $1 billion park-repairs deficit, which has left its falls in desperate need of pedestrian bridges, railings, walkways, and upgraded water and electrical systems. Last year, the New York Times had one word to describe the 400 acres surrounding Niagara: "shabby."

But even in reduced circumstances, Niagara is worth the trip. There's actual nature on the American side-it feels like a park, not a Vegas Strip knockoff. And that nature has a pedigree: The park was designed by landscape architect Frederick Law Olmsted, the man behind New York's Central Park. In April, the state launched a $25 million project that will address the park's urgent infrastructure needs as well as restore elements-native plantings, intimate overlooks-outlined in Olmsted's plan. Today, prime viewpoints can be found on Goat Island, which sits between the American and Canadian falls. But the best bang for your buck is the $1 elevator ride up the Observation Tower at Prospect Point, which yields a priceless view from 220 feet. No raincoats necessary.

Where to Stay: The 39-room Giacomo, in a 1929 Art Deco building, opened three years ago with modern furniture and abstract art; rooms also have free Wi-Fi, Keurig coffeemakers, and refrigerators (thegiacomo.com, doubles from $139). The Giacomo is two blocks from the park, and you can see the rapids from the hotel's 19th-floor Skyview Lounge.

While You're There: If you've brought your passport, the Butterfly Conservatory at Canada's Niagara Parks Botanical Gardens is worth a border crossing. Its 2,000 airborne inhabitants (from 45 species) have been known to alight on certain lucky visitors (niagaraparks.com, admission $13, parking $5).

How to Help: Donate to any New York state park via the Natural Heritage Trust (nysparks.com), the Alliance for New York State Parks (allnysparks.org), Parks & Trails New York (ptny.org), or any individual park's website.

Park Info: First St. and Buffalo Ave., Niagara Falls, N.Y., 716/278-1796, nysparks.com, open 24 hours daily, admission free.

Ludington State Park

Michigan

Michigan's Recreation Passport Program, a $10 annual park pass, has pumped $6 million into the state and local parks system since it launched in 2010. The bad news: Collectively, parks around the state still need more than $300 million in repairs. The roof at Ludington's nature center buckled under heavy snow in 2009, and it still hasn't been fixed. Now the entire building has to be torn down. Sadly, there's no money for that either.

Ludington deserves better. Snug between Lake Michigan and Hamlin Lake, the nearly-5,300-acre park has seven miles of sandy, dune-strewn beaches, a historic lighthouse you can climb, more than 20 miles of hiking trails (plus paths for biking and cross-country skiing), and the shallow, clear Big Sable River, which is perfect for drifting down in an inner tube. No wonder Ludington has been a Great Lakes-area favorite since it was established 76 years ago.

Where to Stay: Ludington's four campgrounds fill up quickly; reserve campsites six months in advance or cabins and yurts one year out, when openings are posted (midnrreservations.com, camping from $16). You can also try the Lamplighter Bed & Breakfast, an 1892 home with an original oak banister, leaded-glass windows, and a porcelain-tiled fireplace (ludington-michigan.com, doubles from $115).

While You're There: Explore downtown Ludington, a onetime logging-town-turned-beach-retreat, or go further back in time at Historic White Pine Village, two miles south. The site has a collection of 29 restored (or re-created) 19th-century buildings, enhanced with educational exhibits (historicwhitepinevillage.org, adults $9).

How to Help: Make a tax-deductible donation to a specific park or purchase a gift certificate (for camping fees, mooring fees, and merchandise) at michigan.gov.

Park Info: 8800 W. M-116, Ludington, Mich., 231/843-2423, michigan.gov, open daily 8 A.M.-10 P.M., admission $8.

Cache River State Natural Area

Illinois

There are more famous swamps than the one in Cache River State Natural Area, a nearly 15,000-acre Illinois state park 30 miles from the Kentucky border. The Everglades, say, or Okefenokee. But who wants a crowd along? One of the northernmost examples of a true Southern swamp, the delightfully under-the-radar Cache River park gets only about 200,000 annual visitors-that's about one visitor per acre per month.

Other life forms aren't nearly so scarce here: The park's wetlands, floodplains, forests, and limestone barrens harbor more than 100 threatened or endangered species. It's best explored by canoe, along six miles of paddling trails that bring you face-to-face with massive tupelo and cypress trunks. There are also 20 miles of foot trails in the park and a floating boardwalk that leads to the center of Heron Pond, which is carpeted in summer with a bright-green layer of floating duckweed. BYO boat, or rent one from White Crane Canoe and Pirogue Rentals in Ullin, Ill., about 12 miles west (whitecranerentals.com, canoe rental $15 per person per day).

Where to Stay: A half-hour drive west of the park, Anna, Ill., has a handful
of antiques shops, a pottery museum, and the Davie School Inn, an 11-room, all-suite B&B in a converted 1910 schoolhouse (davieschoolinn.com, doubles from $100).

While You're There: Work in a detour to Metropolis, Ill., a.k.a. Superman's hometown. The Super Museum has more than 20,000 TV and movie props and other collectibles amassed by owner Jim Hambrick (supermuseum.com, admission $5).

How to Help: Join the Friends of the Cache River Watershed nonprofit (friendsofcache.org).

Park Info: 930 Sunflower Lane, Belknap, Ill., 618/634-9678, dnr.state.il.us, visitors center hours Wed.-Sun.
9 A.M.-4 P.M., admission free.

Red Rock State Park

Arizona

When the grandest of canyons is in your backyard, it's easy to take your lesser landmarks for granted. That seemed to be the case in Arizona, which targeted 13 of its 22 parks for closure in 2010, including Red Rock.

Fortunately, not everyone was so quick to write off the little guys. Red Rock's lifeline arrived via the Yavapai County and City of Sedona governments and the Benefactors of Red Rock State Park, which jointly raised $240,000 to temporarily finance the park. That will keep this 286-acre nature preserve open at least until June 2013.

Among the best ways to take in the rust-colored canyon are the park's five miles of hiking trails and one mile for biking and horseback riding. Birding is big here, too: Every Wednesday and Saturday at 8 A.M. (7 A.M. in summer), guides lead aviary walks along the banks of Oak Creek, and guests can follow along with the park's checklist of feathered regulars: black-chinned hummingbirds, great blue herons, and the occasional yellow-billed cuckoo.
Everything in Red Rock is colorful!

Where to Stay: Sedona's hotels can be pricey, so try an apartment or casita rental on vrbo.com, with over 150 local listings-some under $100 per night.

While You're There: Get your massage fix. Sedona regulars favor Stillpoint...Living in Balance, naming its massage the "Best of Sedona" in a local poll the past four years (stillpointbalance.com, 70-minute massage $90).

How to Help: Visit benefactorsrrsp.org to make a donation, or sign up for a subscription to Arizona Highways magazine: $5 of the $24 cost will be directed to the park of your choice (arizonahighways.com).

Park Info: 4050 Red Rock Loop Rd., Sedona, Ariz., 928/282-6907, azstateparks.com, open daily 8 A.M.-5 P.M., admission $10 per car or $3 for individuals.

Blackwater Falls State Park

West Virginia

Blackwater Falls's namesake cascade isn't just the most picturesque spot in this 2,456-acre park-it's also one of the most photographed places in the state. The area is equally eye-catching when it's dressed in the bright greens of spring, the Crayola-box colors of autumn, or silvery winter, when parts of the falls freeze into man-size icicles. The falls themselves-more brown than black-get their distinctive hue from tannic acid that leaches into the river from hemlock and red spruce needles upstream.

But there's something potentially more serious darkening the future of West Virginia's state parks: hydraulic fracturing (a.k.a. fracking) wells that could be built on ecologically significant public lands. Surface rights don't always include the mineral rights when park land is acquired; in West Virginia, the mineral rights under approximately 40 percent of the state parks, including Blackwater, are privately held. It's those split-custody parks that experts say are at greatest risk. Chief Logan State Park, about 200 miles away, already lost a fracking battle when the state's Supreme Court, over the objection of the W. Va. Department of Environmental Protection, voted unanimously in 2010 to allow natural gas drilling in the park-a process that typically calls for not just drilling, but also the construction of roads and the clear-cutting of trees. Almost the entire state of West Virginia sits atop the Marcellus Shale, the natural-gas source targeted at Chief Logan, which means that a dozen or so other parks could soon find themselves fighting for their rights, too.

Where to Stay: Outdoorsy types can pitch a tent at 65 campsites, or upgrade to one of 26 deluxe cabins with full kitchens, private bathrooms, and fireplaces-but not A/C. For that creature comfort, you'll need to book a night in the 54-room lodge, which also has a game room and an indoor pool (blackwaterfalls.com, camping from $20, lodge rooms from $84).

While You're There: Plan a day trip to the small yet lively town of Elkins, W. Va., taking the hourlong scenic route through Blackwater and Canaan Valley State Park. In Elkins, the Randolph County Community Arts Center hosts free concerts, arts workshops, and traveling exhibitions year-round-its third Smithsonian exhibition just came through this summer (randolpharts.org).

How to Help: Donate cash, stock, or even office supplies to Friends of Blackwater, a group focused on preserving the ecosystem of Blackwater Canyon (saveblackwater.org).

Park Info: 1584 Blackwater Lodge Rd., Davis, W. Va., 304/259-5216, blackwaterfalls.com, open 6 A.M.-10 P.M., admission free.

Honeymoon Island State Park

Florida

You'd expect a place called Honeymoon Island to be dreamy, and with four miles of white beaches and two more of nature trails (where osprey, terns, and bald eagles nest), Florida's most popular state park is tailor-made for romantic strolls. Even back when it was known as Hog Island-before a 1930s developer put up a string of beach cottages and renamed the spot to lure newlyweds-visitors to the tiny barrier island were all but guaranteed dolphin sightings and stunning sunsets over the Gulf of Mexico. The cottages are gone now, but more than a million people still cross the bridge to the island each year to spend the day swimming, surfing, kayaking, and collecting shells along the north shore. The only thing you can't do is sleep under the stars. Last year Florida proposed adding a privately run RV campground to Honeymoon Island State Park, citing high demand for more camping opportunities in state parks. However, area residents protested the campground and its potential disruption of the park's ecosystem, and the plans were dropped. For now, at least, the beaches close at sunset, with only those osprey, terns, and eagles to look after them.

Where to Stay: Hotels and vacation rentals abound in the adjacent towns of Dunedin and Clearwater. Frenchy's Oasis Motel, 11 miles south of the park, gives the old-fashioned motor lodge a Mid-Century Modern spin with starburst clocks, a bright, citrusy palette, and free Wi-Fi (frenchysoasismotel.com, doubles from $119).

While You're There: Before a hurricane divided them in the 1920s, Honeymoon Island and neighboring Caladesi Island were a single land mass. Today, you can only reach car-free Caladesi by boat (or Jet Ski). The only public ferries leave from Honeymoon Island; rides take 20 minutes and run every half hour starting at 10 A.M. (caladesiferry.org, $14 round-trip).

How to Help: Make a tax-deductible donation through Florida's Help Our State Parks (HOSP) program (mailed to the Florida Department of Environmental Protection, Division of Recreation and Parks, 3900 Commonwealth Blvd., MS 540, Tallahassee, FL 32399).

Park Info: 1 Causeway Blvd., Dunedin, Fla., 727/469-5942, floridastateparks.org, open daily 8 A.M. to sundown, admission $8 per vehicle ($4 for solo drivers) or $2 for pedestrians and cyclists.

Katy Trail State Park

Missouri

The largest rails-to-trails conversion in America, the 240-mile Katy Trail spans Missouri's midsection, from Clinton in the west to Machens in the east, along the former track of the Missouri-Kansas-Texas (MKT) Railroad (a.k.a. the Katy). The mostly flat path is open to hikers and cyclists-and in some sections, horseback riders-and traverses historic railroad bridges, tunnels, forests, valleys, and open fields. In spots, it skirts the edge of the Missouri River. Some hardy souls tackle the whole trail (a roughly five-day undertaking for an experienced cyclist). Those who prefer a more leisurely trek should consider a daytrip between Rocheport and Boonville, two early-19th-century towns (the latter established by Daniel Boone's offspring) separated by 12 miles of nature preserves, vineyards, and river views. Of course, all those miles of pathway-including 500 bridges and 60 buildings-don't just tend themselves, and it is estimated that the Katy Trail has $47.5 million in deferred maintenance projects, accounting for nearly a quarter of the total $200 million backlog of repairs needed in Missouri's parks.

Where to stay: There are no campgrounds in the park, but you can have your pick of small-town inns along the route. Some cater to cyclists with extras such as free laundry service, double-size whirlpool tubs, and free bike storage and tune-up tools. Rocheport's School House Bed & Breakfast, in a three-story brick schoolhouse from 1914, sweetens the deal with fresh-baked cookies at check-in (schoolhousebb.com, doubles from $149).

While you're there: Missouri's 100-plus wineries produce nearly half a million cases of wine each year. Les Bourgeois Vineyards and Winery, the state's third-largest, is just outside downtown Rocheport on a bluff overlooking the Missouri River (missouriwine.com, open daily 11 A.M.-6 P.M.). Bonus: The School House Bed and Breakfast gives rides to guests who are too tired to make the uphill trek.

How to help: Donation boxes are posted at all trailheads; you can also "adopt" a section of trail or a bike rack or make a tax-deductible donation at katytrailstatepark.com.

Park Info: Clinton, Mo., to Machens, Mo., 800/334-6946, katytrailstatepark.com, open sunrise to sunset, admission free.

Valley of Fire State Park

Nevada

In the past four years, general funding for Nevada's state parks has been reduced by roughly 60 percent, with almost $3 million cut in 2011 alone. While no closures are planned, the parks are suffering from reduced maintenance, and staffing levels have been cut by 19 percent, even as attendance has grown. One of the state's best-loved parks is the Valley of Fire, 42,000 arid acres about an hour's drive northeast from Las Vegas. The park delivers its own kind of high-stakes drama, trading neon and nightclubs for 150-million-year-old sandstone formations and 3,000-year-old petroglyphs (images carved in rock). You could even say it has star quality: The surreal, burnt-sienna landscape stood in for Mars in the 1990 movie Total Recall.

If you're embarking on your own photo safari or DIY sci-fi flick in Nevada's largest state park, don't miss Arch Rock, Elephant Rock, or the Beehives, all of which are essentially solid-stone versions of exactly what they sound like. And be sure to take snapshots with and without people in the frame-the structures are even more outstanding when you can get a sense of their scale. Most important of all: Bring lots of water with you. There are few
facilities within the park, and the sandy stretches of some hikes make them more strenuous than you'd think, particularly in the summer, when Mojave Desert temperatures top 120 degrees. Best to come in spring or fall for a more comfortable trip.

Where to Stay: The park contains 72 campsites, including RV spots with water and electrical hookups (campsites $20 per night plus $10 for hookups; $2 discount for Nevada residents). If that's not your speed, the family-run North Shore Inn has a pool, in-room fridges, and powerful air conditioning (northshoreinnatlakemead.com, doubles from $85).

While You're There: When you've had your fill of heat, the waters of Lake Mead are about six miles away. Boat rentals for fishing and water skiing are plentiful; the nearest outfitter is Echo Bay Marina, on the lake's northern reach (echobaylakemead.com, five-seat fishing boats $60 for a half-day rental).

How to Help: There's a donation jar in the visitors center where you can deposit a contribution.

Park Info: Interstate 15 at Highway 169, Exit 75, Overton, Nev., 702/397-2088, parks.nv.gov, open daily sunrise to sunset (except for campers), admission $10 per vehicle (or $8 for Nevada residents).

Ohiopyle State Park

Pennsylvania

If ever there were an all-purpose park, southwestern Pennsylvania's Ohiopyle State Park is it. Looking for waterfalls? It has four (including the one pictured below, which seems as if
it must have inspired Frank Lloyd Wright's Fallingwater house, just five miles away). Trails? Hikers get 79 miles of them-plus 27 miles for cyclists, 11 for folks on horseback, and nearly 40 for cross-country skiers. And why not throw in a natural water slide or two? The lifeblood of the 20,000-acre park, however, is the Youghiogheny River Gorge-a.k.a. the Yough. The Middle Yough, which flows to Ohiopyle from Confluence, Pa., is the gentler
section, with Class I and II rapids for rafters and kayakers; the Lower Yough, downstream, gets up to Class IV whitewater. Combined, they attract a good chunk of the 1 million people who visit the park every year.

But if Ohiopyle has a little something for everyone, there's a lot more to the park than meets the eye-and that's just the problem. Like some 60 other Pennsylvania state parks (as well as West Virginia's Blackwater Falls, on page 60), Ohiopyle is situated atop the natural-gas-rich Marcellus Shale-and the state doesn't own the mineral rights underneath the park-. In fact, the mineral rights to about 80 percent of Pennsylvania's state park lands are privately owned (or available for lease), and under current legal precedent, mineral rights are given precedence over surface rights. Parks advocates fear that it won't be long before a drilling rig is erected in a state park. Sound alarmist? Well, Pennsylvania issued its first lease for oil and gas extraction on state forest lands back in 1947 and drilling continues today.

Where to Stay: The quietest campsites in Ohiopyle's Kentuck campground are the walk-in sites numbered 51-64 and 103-115; however, some folks have found the camp's firm 9 P.M. quiet hours a little too restrictive. If your brood tends to get livelier as the night wears on, consider a vacation rental in Hidden Valley, Pa., or Seven Springs, Pa., both less than 30 miles to the northeast; these two ski towns have solid selections of rental condos and homes that can be deeply discounted in the off-season (vrbo.com).

While You're There: Two Frank Lloyd Wright homes are within a 10-minute drive of the park: world-famous Fallingwater, designed in 1935 (fallingwater.org, admission $8), and the lesser-known Kentuck Knob, built in 1956 (kentuckknob.com, tours from $20).

How to Help: Send a donation through paparksandforests.org, or pick up a 16-month (Sept. 2012-Dec. 2013) Civilian Conservation Corps wall calendar, the profits from which are reinvested in parks (888/727-2757, $8.50).

Park Info: 124 Main Street, Ohiopyle, Pa., 724/329-8591, dcnr.state.pa.us, open from dawn to dusk, admission free.
