Lewis and Clark Caverns State Park

Lewis and Clark Caverns State Park, in Whitehall about forty-five minutes east of Butte, protects a limestone cave system filled with stalactites, stalagmites, columns and delicate formations. It is among the most popular state parks in Montana, and the caverns are open only for guided tours, which run from late May through September. The two-hour Classic Tour covers about two miles and includes stairs and some tight passages, while the shorter Paradise Tour follows about half a mile and is easier on the legs. Above ground, the park has campsites, picnic areas and more than thirty miles of trails through dry hills and canyons, with views toward the Jefferson River valley. The caverns were not visited by the explorers they are named for, but they have been a local attraction for more than a century. Inside, the temperature stays cool year-round, which makes the caves a welcome break in hot weather.

Reserve ahead for summer weekends, since tours have limited capacity and the approach to the cave entrance involves a climb on a trail from the visitor center. Wear sturdy shoes with good grip, bring a jacket and avoid heavy bags. Tours are not suitable for people with claustrophobia or limited mobility on the Classic route, but the Paradise tour is easier. Children are welcome but must be able to walk the full distance, as strollers are not allowed.

The drive from Butte is straightforward on the interstate, and the park makes a satisfying half-day excursion, with time for a picnic and a short hike. If you are heading toward Bozeman or Yellowstone, it is also a convenient stop on the way. Weather can change quickly, so check the forecast, and remember that the park operates seasonally, so confirm dates before you drive.

Photography is allowed in the caves, but handheld lights are limited and flash is discouraged. Do not touch formations, since oils from skin damage them. Bats may roost in parts of the system, and rangers can explain how the park protects them. Camping at the park is a good option for families who want to stay overnight.

Pair the caverns with a stop at Three Forks or a meal in Whitehall on the way back. If you only have a day for a day trip from Butte, this is an excellent choice for families and nature lovers.

Before you go, check whether tour tickets are available online or only at the visitor center, since policies change. Arrive early, because the walk to the cave entrance climbs a few hundred feet and takes time. Bring water, wear layers and keep small children close on the trail and the stairs. Leave tripods and large bags in the car, as they are not practical in tight passages.

The park is also a pleasant place to spend a few extra hours. The visitor center has displays on the cave's discovery and geology, picnic tables sit under shade, and the hills offer short hikes with views of the Jefferson River valley. If you plan to camp, reserve a site ahead, since summer weekends fill quickly. A stop at nearby Three Forks or Whitehall on the way back makes a pleasant end to the day.
