Lava River Cave

Located in Coconino National Forest northwest of Flagstaff, Lava River Cave is a mile-long underground lava tube formed over 500,000 years ago. Visitors can hike through the dark cavern, where temperatures remain between 35 and 45 degrees Fahrenheit year-round regardless of outside heat. The natural underground trail features unique volcanic rock formations, low ceilings, and uneven basalt terrain.
