State Park · Montana
Montana's first state park, built around a ranger-guided tour of one of the largest limestone caverns in the Northwest, with a seasonal cave-tour window, surface trails, and a campground.
Field briefing
Lewis and Clark Caverns State Park changes fast with season and elevation.
Before you go
Cave tours run May 1 through September 30, and from Memorial Day through Labor Day they are reservation-only and must be booked at least 24 hours ahead, so lock the tour before the rest of the trip.

Weather, crowds, and what the season changes about the trip.
Cool and green on the surface; the cave stays a steady cool temperature year-round.
Pack Warm layer for the cave, grippy shoes for damp steps, and a rain shell up top.
Warm and bright outside, with reservation-only cave tours and the busiest visitation.
Pack Booked tour time, a light jacket for the cave, and water for the surface trails.
Crisp and quieter, with first-come cave tickets returning in the shoulder season.
Pack Warm cave layer, sturdy shoes, and a check on the season's final tour dates.
Cold and quiet, with the cave closed and only the surface park open.
Pack Insulation and a plan that does not depend on a cave tour.
Classic cave tour
The reason to come: a ranger-guided walk through richly decorated limestone chambers. It involves a steep approach trail, many stairs, and tight passages, so treat it as an active outing.
Paradise and Candlelight tours
Alternative ranger-guided options, including a more relaxed Paradise tour and a lantern-lit Candlelight tour that recreates the early days of exploring the cave.
Surface trails and campground
Above ground, walking trails, a visitor center, and a campground let you make the cave the centerpiece of an overnight rather than a quick stop.
Book the tour time first, then treat surface trails, overlooks, or visitor-center stops as the flexible pieces. For one day in Lewis and Clark Caverns State Park, make Classic cave tour the non-negotiable, add Paradise and Candlelight tours only if the first stop runs clean, and keep Surface trails and campground as the flexible finish.
Turn Lewis and Clark Caverns's conditions into water, pack, and sleep-system decisions.

Camp in the park to make an easy morning of the cave tour and the surface trails. Three Forks and Whitehall are the nearest small towns, and Bozeman, about an hour east, is the practical larger base for hotels, food, and resupply.
Camping reservations
The cave tour is the centerpiece and is reservation-only in peak summer, so secure a tour time before you plan camping. The park campground then turns the visit into a relaxed overnight.

Getting there
Arrival note
Lewis and Clark Caverns lies along Montana 2 between Three Forks and Whitehall in southwest Montana, about an hour west of Bozeman off Interstate 90.
Shuttle access
A car is required, and the cave entrance sits up a steep access road and trail above the visitor center, so allow time and energy for the approach.
Pair this with lodging: sleep where the park transfer is simple, especially if your route needs an early start.
In peak summer, yes. From Memorial Day through Labor Day, cave tours are reservation-only and must be booked at least 24 hours in advance. In the shoulder season, unsold tickets are first come, first served.
Cave tours run from May 1 through September 30. The cave closes in winter, when only the surface park, trails, and campground areas remain accessible.
Somewhat. The Classic tour involves a steep approach trail, many stairs, and tight, sometimes low passages, so it is best treated as an active outing rather than a casual walk.
