Forestville/Mystery Cave State Park
Hidden in the bluff country of southeastern Minnesota, Forestville/Mystery Cave State Park combines two extraordinary attractions into one destination: a restored 1800s frontier townsite and Minnesota’s longest cave system, with over 13 miles of mapped underground passages. Above ground, hardwood forests and trout streams complete a park that genuinely has no equivalent in the state.
Why Forestville/Mystery Cave Stands Out
This is one of the few state parks in America that lets you explore underground cave formations, tour a preserved 19th-century village, and fly-fish for brook trout — all in the same day. Mystery Cave’s passages contain formations created over hundreds of thousands of years, including stalactites, stalagmites, flowstone, and turquoise underground pools that reflect dramatic cave lighting. The Forestville townsite, managed by the Minnesota Historical Society, is a time capsule of 1800s frontier life.
Mystery Cave Tours
| Tour Type | Duration | Difficulty | Highlights |
|---|---|---|---|
| Scenic Tour | 1 hour | Easy (wheelchair accessible) | ¾-mile paved trail, mineral deposits, underground pools, dramatic lighting |
| Lantern Tour | 1 hour | Moderate | Flashlight-only exploration, cave geology interpretation, stone stairs |
| Geology Tour | 1 hour | Moderate | Deep dive into cave formation processes and mineral identification |
| Wild Caving Tour | 2.5–4 hours | Strenuous | Undeveloped passages, crawling, squeezing — boots and gloves required |
2026 Season: Cave tours run May 9 through September 7, 2026. Weekday tours depart hourly from 10 AM to 4 PM. Weekend tours depart every 20 minutes from 10 AM to 5 PM, with early 9 AM departures on Saturdays. The Scenic Tour costs $15/adult, $10/children (5–12), free for children under 5. Reservations are highly recommended — especially for Wild Caving slots, which fill fast.
Insider Tip: The Lantern Tour offers a completely different atmosphere from the Scenic Tour — the darkness and flashlights reveal textures and details you’d miss under standard lighting. Children under 8 are not permitted on this tour due to uneven stone stairs. For the Wild Caving Tour, bring clothes you don’t mind getting muddy — you will crawl, stoop, and squeeze through undeveloped passages.
Historic Forestville
Located in the park’s separate Forestville unit (about 10 miles from the cave), this restored 1800s townsite offers guided tours of buildings and costumed interpreters who bring frontier Minnesota to life. Managed by the Minnesota Historical Society, admission is $14/adult, $10/youth (5–17), and free for children under 5. The townsite operates seasonally — check the MHS website for current hours.
Above-Ground Activities
The park spans both banks of the South Branch of the Root River, with 16 miles of hiking trails through mature hardwood forests, limestone bluffs, and spring-fed streams. The river is a designated trout stream — brook, brown, and rainbow trout are all present. In winter, the trails transform into excellent cross-country skiing routes, and the bluff country scenery is spectacular during fall color season.
Camping
The park offers 73 drive-in campsites (23 with electric hookups), plus a primitive group camp and walk-in sites tucked into the forest. Sites are reservable through the Minnesota DNR reservation system. The campground is positioned near the Forestville unit, not the cave — plan accordingly.

Mystery Cave is Minnesota’s longest cave, with over 13 miles of mapped passages. The standard Scenic Tour covers about ¾ mile of developed trail. The Wild Caving Tour ventures into undeveloped sections far beyond the standard route.
Is Mystery Cave wheelchair accessible?
Yes — the Scenic Tour follows paved trails and metal bridges and is fully wheelchair and stroller accessible. Other tours involve stairs and uneven terrain.
Can I use GPS to find the cave?
The Minnesota DNR strongly advises against relying solely on phone GPS for directions to Mystery Cave, as navigation apps frequently provide incorrect routing in this rural area. Follow the posted road signs instead.
