LEWIS AND CLARK CAVERN STATE PARK
Montana's first and best-known state park showcases one of the most highly decorated limestone caverns in the Northwest. Naturally air conditioned, these spectacular caves, lined with stalactites, stalagmites, columns, and helicitites, date back through time. See the geologic development, the history of early exploration and gain an insight into the delicate ecology of this world without light. Plan to spend a minimum of two hours to hike two miles on a guided tour through the caverns. The park also provides hiking trails, a visitor center, an amphitheater, several picnic areas, a large campground, showers, RV dump facilities, tipi, and three rental cabins. You can use this park as ?base camp? while you enjoy several nearby parks and the adjacent Jefferson River.
