North Crater Flow Trail is a very easy hike in Craters of the Moon National Monument near Twin Falls, Idaho. The monument says "this trail takes you onto the North Crater Flow, a pahoehoe flow that spilled from the North Crater vent about 2,200 years ago. Signs along the, trail introduce other typical features: pressure ridges, squeeze ups, aa lava, and rafted blocks." 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.
