About Lewis & Clark Caverns State Park is Montana's first and best-known state park featuring one of the most decorated limestone caverns in the Northwest. Naturally air conditioned, these spectacular caves lined with stalactites, stalagmites, columns, and helictites are electrically lighted and safe to visit. Above ground, a self-guided nature trail provides opportunities to understand the natural surroundings. The park is open year around, but guided tours are conducted daily only between May 1 and September 30. The park has two visitor centers, interpretive displays and evening programs presented during the summer months. The site encompasses 3,000 acres at an elevation of 4,300 and 5,600 feet. Golf course and museums are located nearby in Three Forks and Whitehall.
