Lewis & Clark Caverns State Park
Lewis and Clark Caverns State Park
Montana's first state park, where a guided tour takes you through a limestone cave filled with stalactites, with a constant temperature of about 10°C inside.
The caverns are Montana's first state park. Inside the limestone cave, stalactites, stalagmites, flowstone, and “cave pearls” are densely scattered, and the temperature stays at around 10°C year-round. Visitors can enter only on ranger-led tours. The classic tour lasts about 2 hours, covers roughly 3 km in total, and involves hundreds of steps. Some passages require stooping or even sliding, so bring a jacket and non-slip shoes. A gentler “Heaven Tour” is also available. Summer tour slots fill up quickly, so book in advance on the official website. The park is about 75 km from Bozeman (via I-90 and MT-2), and it can be combined with Norris Hot Springs and Missouri Headwaters State Park for a day trip.
