Hell's Half Acre Lava Flow


Visitors who take the time to walk through this approximately 4,000-year-old lava flow can learn how it was created and how plants and animals have managed to adapt to this harsh environment. Interpretive signs are located along the trails.


From Idaho Falls, take Interstate 15 south for 15 miles to either of 2 rest areas, and look for directional signs to the trails from the parking lots.
