Lewis and Clark Caverns in Montana
Lewis & Clark Caverns in Montana are a spectacular geological stop on your way to or from Yellowstone National Park and your journey on US 287 through the backroads of the Madison Valley. The impressive geological features of these Montana caverns include stalactites, stalagmites, helictites and columns. Although named after the famous explorers, the Lewis and Clark Expedition crossed the park property, but did not actually discover the caverns. The name was given in honor of the expedition by President Theodore Roosevelt and designated as a national monument on the same day as the Grand Canyon.
The Montana caverns Lewis and Clark inspired, later became a state park while the Grand Canyon became a National Park. Viewing the caverns is an almost 2 mile hike in cool comfort of the natural underground air-conditioning. Tours are given daily throughout the summer. The park also offers camping, hiking and biking trails, interpretive displays and a new visitor center with a gift shop, food and beverage options. Ranger and interpretive programs are presented during the summer. The site encompasses 3,015 acres and the entry area is at an elevation of 4,300 feet and the caverns area is at an elevation of 5,300 feet.
