Beginning just 15,000 years ago, lava flows oozed up from a fissure - today called the Great Rift - in the much-studied Snake River Plain, creating a mystical landscape that is interesting to visit any time of the year. You won't find a Mt. St. Helens-type of volcano here, but you will learn about spatter cones, cinder cones and fissures... More

Neat place to visit with the scenic lava landscape. We went during a hot day in summer and it was a little stifling. A lot of hiking required if you want to see everything so be prepared!

We found this place a little out of the way from our route from Jackson, WY to Salt Lake City, UT. However, this extra distance was worth it. This year was supposedly an exceptional year for "cinder gardens," which are thousands of little flowers growing near the roadside. The details in the flows were also spectacular. However, the highlight for... More

this was the first national park we visited on our ATI tour and by comparison its very small. however, the roads and pathways are clearly laid out and even allow to get away from the masses at times. we were their in june and the temperature was very pleasant. the visitors centre talked a lot about the use of grass...

We arrived in mid June just as the wild flowers carpeted the lava. The flowers only last two weeks so we were fortunately to select the best time to view this phenomenon. We did not know that lava that is thousands/millions of years old could support such delicate beauty as these tiny flowers. The lava formations are amazing. The park... More

We drove up from Twin Falls to Jackson with a stopover at COTM. We spent two hours doing the North Crater walk and a cave tour. You do not need to do a guided tour of the caves; can do on your own (duh). You don't have to stop at the Visitor Center either -- you can pay and get... More

This place is really out in the middle of nowhere, but then again, where else would you expect to find old volcanoes and lava beds? It was quite interesting to see what a volcano can do. The folds of lava and the cracks in its crust were very interesting. The volcanic cones had pathways so you could walk up to... More

This place is unlike anything I've seen in the U.S. Other than near Hawaiian volcanoes. The black lava seems never ending. It was cool to walk around and see so many formations. My kids enjoyed earning their junior ranger badges.
