Quick Links

Montana is one of the most stunning states in the country and is home to the stunning Glacier National Park. But not all of Montana's attractions are above the surface - one of the top state parks to discover is the Lewis and Clark Caverns State Park. It is famous for having some of the most decorated caves in the Northwest.

The Lewis and Clark Caverns State Park is located in Jefferson Count in Montana and has a visitor center and ten miles of hiking trails. The caverns are a wonderworld of stalactites, stalagmites, columns, and more - all naturally air-conditioned. For another rewarding subterranean experience, consider visiting the Mammoth Cave National Park next time in Kentucky.

Discovery & History Of The Lewis And Clark Caverns

The explorers, Lewis and Clark, are known to have camped within sight of the caverns in 1805, although they didn't see it. The cave was first explored (with documented evidence) in 1898. It quickly became a tourist attraction, with tours first being offered by Dan A. Morrison in 1900.

  • Park Size: 3,000-acre (1,200 ha)

The cave was first called Limespur Cave, but the caverns were later renamed after the explorers as it overlooks around 50 miles of the trail from Lewis and Clark.

The caverns became Montana's first state park in 1938 and are one of the most popular in the state.

The limestone of the Lewis and Clark Caverns is very old, dating back to the Mississippian age between 325 and 365 million years ago (long before the time of the dinosaurs). The caves themselves are thought to have formed during the ice ages when there was more water than today.
