If you want to see something completely different from the usual Montana hiking and fishing trips, Lewis & Clark Caverns is worth the drive. Montana’s first state park sits about 90 minutes west of Bozeman near Whitehall, and it has one of the largest limestone caves in the Northwest. We’ve done the cave tour twice now, once with kids and once without, and the formations inside were more dramatic than I expected.
The park covers about 3,000 acres in the Jefferson River valley. You can camp here, hike trails with views of the surrounding mountains, and poke around the visitor center, but the cave is the main attraction. It’s only accessible by guided tour, and those tours sell out.
Book Your Tickets Online
This is the most important thing I can tell you: buy your cave tour tickets online before you go. The park has strict limits on group size, and I saw multiple families turned away because all the tours were booked for the day. Don’t drive 90 minutes and show up hoping to walk on. Reserve through Montana State Parks ahead of time.
The Cave Tours
The park offers three tour options:
Classic Tour is the full experience. It takes about 2 hours and covers 2 miles with 300 feet of elevation gain, 100+ stairs going up, and 500+ stairs coming down. We did this one without kids. The formations are incredible, the guides are excellent, and you see a lot of the cave. It’s moderately difficult, mostly because of all the stairs and some tight passages.
Paradise Tour is the easier option and what we did with our two kids. It runs about 1.5 hours, covers less ground, and visits two of the main cave rooms. Still impressive formations, just less strenuous. Good for families with younger kids or anyone who doesn’t want to commit to the full tour.
Candlelight Tour is a winter-only option offered in late December. We haven’t done this one yet, but the idea of seeing the cave by candlelight sounds worth the trip. Tickets go on sale the Monday after Thanksgiving and sell out quickly.
Prices (2026): $15 adults, $10 youth (5-14) for the Classic and Paradise tours. The Candlelight Tour runs $25 adults, $15 youth. Kids under 5 aren’t allowed on the Classic Tour.
The Hike to the Entrance
Here’s what caught us off guard: you don’t just walk into the cave from the parking lot. The cave entrance is up the mountain, and the hike to get there is steeper and longer than we expected. My in-laws struggled a bit on the climb. It’s not technical, just steady uphill with some exposure to sun. Budget extra time and energy before your tour even starts.
Keep your eyes on the rock walls along the trail. We spotted fossils embedded in the limestone on our way up.
What to Wear
Bring a layer for the cave, even on the hottest summer day. The temperature inside stays constant year-round, and it’s noticeably cooler than outside. Skip the sandals. You’ll want closed-toe shoes with decent grip for the hike up and for navigating wet rocks inside the cave. The floors are slippery in places.
Inside the Cave
The entrance passage is long and narrow. I’ll admit it gave me a slightly claustrophobic feeling walking in, like the mountain was swallowing you up. But once you get into the main chambers, the space opens up and the formations are worth the squeeze.
The tour guides were excellent. They shared a lot of history and geology along the way and kept our kids engaged by asking the group questions. The kids loved it.
The Visitor Center and Cafe
The visitor center has interpretive displays and a cozy lodge feel with a stone fireplace. Worth a quick look before or after your tour. There’s also a small cafe where we grabbed lunch and ice cream after our tour. Good spot to refuel before the drive back.
Other Things to Do
The park has hiking and biking trails beyond the cave tour. We did a short hike before our tour but didn’t venture too far with the kids. If you’re planning a longer hike and a cave tour in the same day, know that you might be pretty tired by the end. The cave tour alone, including the hike to the entrance, is a workout.
The park also has 40 campsites and a few cabins if you want to make it an overnight trip. Fishing, canoeing, and bird watching are options too.
Visitor Info
Hours: The visitor center is open 9am to 4:30pm daily from May through September. Limited hours October through April.
Day Use Fees: $8 for non-resident vehicles, or free if you have the $9 Montana State Parks sticker on your registration.
Pets: Dogs are allowed in the park on leash but not in the caverns. Kennels are available.
Location: 25 Lewis and Clark Caverns Road, Whitehall, MT. Take I-90 west from Bozeman, exit at Three Forks, and follow Highway 2 west along the Jefferson River. It’s well signed.
The Bottom Line
Lewis & Clark Caverns is a solid day trip from Bozeman, especially for families or anyone interested in geology. The cave formations genuinely surprised me with how impressive they were. Just remember to book tickets online, wear real shoes, bring a layer, and save some energy for the hike to the entrance.
