Good place to stretch your legs at a rest stop. It seems like the southbound rest stop has more hiking than the northbound. Nonetheless, it is worthwhile to do the short hikes and read about the unique geological history.

The rest stops in Idaho just might be the best rest stops anywhere in the lower 48. After taking care of your personal business, walking about this lava laden area is almost like being on the Big Island of Hawaii! Its easy to traverse and...More

You'll have to look hard to find it; it's at a rest stop! But what a cool place to visit! Definitely worth a stop and a chance to stretch your legs on the nice clean trails. Rock formations are very unique.

Let me start by saying dont use Google maps- takes you down a different interstate. Maybe there's a different lava field down there but is off interstate 15 south at a rest stop, mile marker 101. With that said, it is a neat little stop...More

Very clean, organized, and nice! My girls were thrilled to be walking on lava rocks! The path had information stops on it, it is very interesting. Would definitely stop by if ever driving through Idaho again!>

The one I went to was West of Idaho Falls. It was fun! You actually get to hike on the lava, without a paved trail! Sometimes it was difficult to see the next marker and we went a ways out before realizing we took a...More

Amazing place. It did not look like anything on this earth. I would suggest being very fit though as we did not take the normal walkways. Climbing thru the lava rock fields from another direction looked very daunting, but, as a foursome of 70 year...More
