The National Geographic Society announced its newest addition to its luxury travel line: National Geographic Unique Lodges of the World.

This is a collection of 24 boutique hotels on six continents that National Geographic says are committed to excellence, authenticity and sustainability.

From locations like Lizard Island on Australia's Great Barrier Reef to Fogo Island Inn in Newfoundland, the properties were selected in a rigorous evaluation process. National Geographic sent experts to each site to make sure the lodges offer an outstanding guest experience while supporting the protection of cultural and natural heritage and embracing sustainable tourism practices.

"National Geographic opens a new chapter in the power of travel to protect our planet," said Costas Christ, editor at large for National Geographic Traveler magazine, in a news release. "Travelers can feel confident when they stay in one of these lodges that they are helping to safeguard cultural and natural treasures in some of the world’s most incredible places.”
