World's Coolest Caves

Spruce Tree House at Mesa Verde National Park: Colorado
In the 13th century, Anasazi or Ancestral Puebloans built 120 rooms and eight ceremonial chambers (kivas) in this 216-feet-long and 89-feet-deep cliff dwelling. Groups of 60 to 80 people lived here and farmed corn, beans, and squash. At the Metate Room restaurant, you can taste homemade flatbreads with black-bean hummus made from locally grown beans descended from Anasazi plants.
Why It’s Cool: It’s the best-preserved Anasazi cliff dwelling—90 percent is original—and, 700 years later, you can still see plaster paintings of birds and mountain sheep.
