The Lava Trails traverse the desert of the Snake River Plain through contorted landscapes created from multiple lava flows. These Hawaiian-type lava flows are associated with the stretching of the earth’s crust. Hell’s Half Acre lava flow erupted about 4,100 years ago and is 222 square miles or 162,000 acres. The lava flowed at 2,000 degrees Fahrenheit, had the consistency of molasses, and traveled at speeds up to 30 mph.Courtesy of blm.gov

Undeveloped trails offering scenic solitude; short 0.5 mile loop trail and a 4.5-mile trail to the main vent of the Hell’s Half Acre flow. Trails are primitive and marked with poles across lava. A fire ring and other amenities are located at the trailhead.Courtesy of blm.gov
