Below is a passages adapted from a website.

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: Taking 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(罩蓬). 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”.

Dog Bark Park Inn B&B

Where: Cottonwood, Idaho         

How much: $92 a night

Why it’s cool: This doghouse isn’t just for the family pet. Sweet Willy is a 30-foot-tall dog with guest rooms in his belly. Climb the wooden stairs beside his hind leg to enter the door in his side．You can relax in the main bedroom, go up a few steps of the loft(阁楼）in Willy’s head, or hang out inside his nose. Although you have a full private bathroom in your quarters, there is also a toilet in the 12-foot-tall fire hydrant (消防栓）outside.

Gamirasu Cave Hotel

Where: Ayvali, Turkey            

How much: Between $130 and $475 a night.

Why it’s cool: This is caveman cool! Experience what it was like 5,000 years ago, when people lived in these mountain caves formed by volcanic ash. But your stay will be much more modern. Bathrooms and electricity provide what you expect from a modern hotel, and the white volcanic ash, called tufa, keeps the rooms cool, about 65℉in summer. (Don’t worry---there is heat in winter.)

Treebones Resort

Where: California, America        

How much: $100 a night

Why it’s cool: You can sleep in a “room” any night, but how often do you get the chance to sleep in a yurt. What’s a yurt? Good question. Yurts are the name given to guest rooms at the Treebones Resort. These spaces provide all of the accessibility to nature you’d enjoy in a tent, but with all the comforts of a cabin. In one of sixteen yurts, you will doze off(打盹儿) while gazing at the stars that can be seen through a sky dome.
