Lewis and Clark Caverns

On the Back Road to Yellowstone

Built by water, limestone and time, the Lewis and Clark Caverns State Park is Montana’s first and best-known state park. Naturally air conditioned, these spectacular caves lined with stalactites, stalagmites, columns, and helictites are lit and safe to visit. An above ground, a self-guided nature trail provides opportunities to understand the natural surroundings. The area also features 10 miles of hiking trails in the Jefferson River Valley.

The park is open year around with guided tours conducted daily between May 1 and September 30. Access to the caves by guided tour only. The park has two visitor centers, interpretive displays and evening programs presented during the summer months.
