The Caves Trail (CMNM)

Idaho by v8.6m

Activities & Features


The Caves Trail is a moderate hike in Craters of the Moon National Monument near Twin Falls, Idaho. The monument says "on a summer day, the cool, dark lava tubes along the Caves Trail offer a radical change from the brilliant light and blistering heat on the surface. Indian Tunnel, one-half mile from the parking lot, is the largest cave and the easiest to visit. Skylights permit enough daylight to enter so that you do not need a flashlight. The other caves are pitch black, with uneven floors and low ceilings. Be sure you have a good flashlight for every person in your group, and that everyone is physically capable before exploring these caves. A hat and long pants may help protect your head and legs from the sharp rock." There is camping available in Craters of the Moon National Monument.


In the summer of 1969, Apollo 14 astronauts including Alan Shepard, Edgar Mitchell, Joe Engle, and Eugene Cernan trained in Craters of the Moon National Monument. They explored the lava landscape and learned the basics of volcanic geology in preparation for future trips to the moon.
