Everyone else has said it has cool geology and you should stop. They are right. Here are some other details: 1. The cave walk is worth doing. Be prepared with items which have not been in other caves. They don't have white-nose here and want to prevent it. 2. This park does the Junior Ranger program really well. I was... More

We went to the park early so we could go on the 1st Park Ranger Guided tour at 9:00 It was worth it as we learned a lot. The Park Ranger was very good. I would not have wanted to wander around alone.

I don't know that you'd call this a beautiful place, it's more like an alien landscape-- thus the name craters of the moon. There are quite a few trails for all abilities. The majority are paved and level. The caves were a favorite although these do have steep stairs and obstacles. The visitor center is a good starting place. Several... More

This national park is well worth the trip, 40.000 acres of some of the coolest landscape and rock formations on the planet. There is a cool campsite and information center. We stopped there in July 2015 and thought it was super interesting, check it out if your in the area.We were on motorcycles and did not camp.

We spent a couple hours touring the museum, listening to the guide and driving to the viewing areas. We could have spent much longer. If you've never seen a volcanic site, this should be on your bucket list. It's been 2000 years since the last activity here but it looks much more recent. This monument really help you understand the... More

It was very cool to see the remnants of volcanic activity in Idaho. I've been to Hawaii and these features were the same. They're often compared to each other throughout the park. Easy hikes, along with some longer treks for the adventurous. Cool cave hikes too if you get a pass.

We spent 2 hours here, went up the Inferno cone (well worth the climb) explored Snow cone and the Spatter cone, and went on the Indian Tube walk. We did the ranger led tour, but you can go on your own. The ranger had some great information, and it enhanced the experience.

My husband loves geology, so we organized our trip around a stop here. Well worth it! Nice vistas, unique scenery, and some fun short hikes. Favorite was hiking up the lava pile to a lovely overlook.

This is not a large park or someplace I would go out of my way to see, but if your in the area you should stop by. The whole park only takes about hour to drive if you don't stop but there are some nice hikes. FYI no dogs on the trails.
