The unique park features camping, hiking & a visitor center amid scenic, sprawling dormant lava fields.
"You may think you’ve been launched into space, but you’re only in central Idaho. Between 2,000 and 15,000 years ago, eight major volcanic eruptive periods occurred, forming the deep cracks, craters, and lava fields currently found in the Craters of the Moon National Monument and Preserve. The area’s sub-surface still has high levels of volcanic and tectonic activity, so the landscape is ever changing. Start at the visitor center, where experts share knowledge about the area’s geology and lithology. From there, explore Indian Tunnel and take a hike around Broken Top Loop trail." [Travel+Leisure]
