Lewis & Clark Caverns State Park, Three Forks

We did the classic tour. Jim was our guide. You can definitely see that he has 17 seasons under his belt. The trek up to the entrance has amazing views along the way (if you aren't scared of heights.) We stopped a few times along the way and Jim gave us fun facts to give everyone a break from the hike. It is almost exactly 2 hours from the start to the finish of the tour. It is a physically demanding tour. I would say 4.5 out of 10 maybe a little less depending on your age and fitness level. But.... it is 100% worth the small effort to see. Only downside. You don't get to see much of the paradise room from where the classic tour stops before the exit.

Super cool tour through the very first state park in Montana. We did the classic which included a short hike up the mountain followed by a descent into the caverns. Really liked the slide as well as all of the cool rock formations. Our tour guide Tom was very knowledgeable and had a lot of interesting facts about the area. Definitely a nice stop for the adventurous and nimble bodied.
