Tayka Hotel De Sal
Where: Tahua, Bolivia
How much: About $95 a night
Why it’s cool: You’ve stayed at hotels made of brick or wood, but salt? That’s something few can claim．Tayka Hotel de Sal is made totally of salt—including the beds (though you’ll sleep on regular mattresses (床垫) and blankets)．The hotel sits on the Salar de Uyuni, a prehistoric dried-up lake that’s the world’s biggest salt flat．Builders use the salt from the 4,633-square-mile flat to make the bricks, and glue them together with a paste of wet salt that hardens when it dries．When rain starts to dissolve the hotel, the owners just mix up more salt paste to strengthen the bricks.
Green Magic Nature Resort
Where: Vythiri, India
How much: About $240 a night
Why it’s cool: Ridding a pulley(滑轮)-operated lift 86 feet to your treetop room is just the start of your adventure．As you look out of your open window—there is no glass!—you watch monkeys and birds in the rain forest canopy．Later you might test your fear of heights by crossing the handmade rope bridge to the main part of the hotel, or just sit on your bamboo bed and read．You don’t even have to come down for breakfast—the hotel will send it up on the pulley-drawn “elevator”.
