We did a short walk here, just two of us, and never saw another soul. We ate our lunch under the covered area at the parking area and were able to use the toilet. Great place to visit, especially if you want to be on...More

Hell's Half Acre is the name of the trails on the lava flow, which cuts across US 20 and I-15 in the Snake River Valley. There are very short trails from both the northbound and southbound rest stops on I-15, about 15 miles south of Idaho Falls. There is a 20 mile trail from US 20, west of Idaho Falls. There is a link to BLM information about all of these if you use Google.
