Traveling in the digital age is a cinch. You can easily find the best local restaurants and make new friends—on your phone.

When it comes to picking a destination for your next big vacation or even your next meal, nothing beats a personal recommendation from someone who has already made the trip. While you don’t always hear a ton about social networks for travelers, there are a number of great ones out there that can help you make those difficult decisions, and perhaps a few new friends in the process.
