Lewis & Clark Caverns State Park is located 19 miles west of Three Forks on Montana 2 or 15 miles east of Whitehall on Montana 2
We took the easier "paradise" tour. It was guided by Jim, a lifelong Montanan. He was a wealth of knowledge of local history and geology. The walk-up to the cavern had great views and was easy, but was about half a mile.
Buy tickets ahead and online. if u've visited another cavern (cave), DO NOT use the same shoes for the safety of the bats. They do sell daily, but first come, first serve and sell out fast. The classic tour is 2 hours, and the only hard part is going up to the cave, which is an uphill climb. We had so much fun inside the cave and expected more crawling, but it wasn't much. Our tour guide was penelope (i think), and she did great. She said she was new and apologized for being awkward. But she did great and appreciated that she had notes. It was like she was just talking to us as if like we've known for a few days. I would like to thank the tour guides for showing up! W/o them we wouldn't be able to see the caverns!!
Seattleite here, being a tourist. Caverns came recommended by a Billings' friend. Definitely worth the drive from Bozeman. Check their schedule online.
Though I read the web description/warnings, I was woefully ill-prepated for this Classic tour jaunt. I'm fat, forty and female and I went alone since here on business. I was last in line all day but Lily never made me feel badly or a burden. Kind, courteous...I felt safe all day. The jokes/puns/facts were perfect. Would recommend for anyone not already on the verge of a heart attack or claustrophobic.
Loved our tour guide, sadly didn't get her name. We did the classic tour guide and prepare for a hike going up along with stairs. However, once to within the cave, you get to go down a SLIDE! A slide in the cave is really cool and one in a kind. Our tour guide even pointed out cool rock formations such as a big foot or a married couple aging. Very informative and fun trip altogether. If in Montana, a highly recommended place indeed.
