Gravel access from US 20 leads to this BLM-managed trailhead parking area on the edge of Hells Half Acre lava field, where dispersed camping is available at no fixed fee. No toilets, water, or electricity are on-site. The area does include a fire ring, picnic tables under a shelter, and a metal grill. Cell coverage is workable, with T-Mobile reaching roughly 19 Mbps and Starlink performing well given an open sky. Some litter and vandalism have been reported. Campers staging trips through camping spots near Idaho Falls will find this stop useful for direct trailhead access the next morning.
