  • We stopped here after the kids found it online. I was a little weirded out the attraction is located at a rest area, but a great little stop to learn about history of the volcano eruption in Idaho...  more »
  • We have stopped here numerous times. It is wonderful to walk the trail. Makes a nice exercise break. Part of the trail is wheelchair friendly.  more »
  • This doesn't look like much from the highway but it is an incredible lava field that you can explore for a little while or all day. Great place to stop and get some fresh air!  more »

  • Pretty mind blown, I would definitely recommend coming during the sun set
  • Park at Lava Hiking Trail parking lot on hwy 20. There is a 1.5 mile loop and a long trail to the volcano. Not exactly an easy hike. There are lots of cracks in the earth you need to jump over, and the trail is hard to see
  • Must see to appreciate.
  • Very cool geological site. This is the wrong site though. The right site I rated 5 stars. Find the other one to get driving directions. Google does show it in the wrong place. You come up on unexpectedly right along I-15 heading south out of Idaho Falls. It just looks like a rest stop. The interstate landscape gets very interesting prior to getting there, but you would totally miss it if you were driving in the dark. Mile marker 101.
  • DON'T FOLLOW GOOGLE MAPS, IT TAKES YOU TO THE MIDDLE OF NOWHERE ON A DIRT ROAD.
