Nerstrand Big Woods State Park

This guide is for day hikers heading to the falls, families planning a spring wildflower or fall color trip, and campers booking for 2027. It covers the trails, the campground, parking (which fills early), seasons, permits and directions. Facts come from the Minnesota DNR park record and the 2025 park map unless another source is named; sources are listed at the end.

The park in brief

The DNR says forests like this once covered 3,000 square miles of south central Minnesota. For thousands of years the ancestors of today's Indigenous people, including the Dakota, managed these woodlands. After 1854, about 96 percent of the forest was converted to fields and homes. The DNR credits local management that favored small family woodlots with keeping this piece intact, and it became a state park in 1945.

The DNR notes the park is much wetter than it was 100 years ago. On flat, poorly drained ground, water now stands too long for most tree species to survive, and the DNR links to its work on climate impacts in the Big Woods.

Hidden Falls and the trails

Hidden Falls is on Prairie Creek. The DNR explains that harder Platteville limestone caps softer Glenwood shale here, and the creek wears away the shale faster, leaving a visible undercut at the bottom of the falls.

The DNR park page says it is "a one-half mile trail to get to the waterfall," starting at the picnic area parking lot. The map's quick-visit tip matches: "The 1/2-mile trip (one-way) starts at the picnic area parking lot." The DNR suggests sturdy hiking shoes for rocks, roots and natural terrain.

Much of the park north of County Highway 29 is hilly and cut by streams, while land south of the road is flatter with clay soil, according to the DNR. For more waterfall walks, see the Minnesota hikes and waterfalls guides.

Dwarf trout lily

The DNR says the park is home to "one of the only populations of the Dwarf Trout Lily," a plant the map says grows only in Minnesota. Protection areas are roped off and posted. Stay on the trails, keep dogs leashed and respect the fences. The Hidden Falls Trail's boardwalk and stairs pass through colonies of the plant.

Camping

The DNR is firm about parking: "Parking off the gravel parking spur is not allowed," so check each site's length before you book.

Season: there is no winter camping at Nerstrand. The DNR's park notes say the campgrounds "will reopen on April 30, 2027," while the seasonal update in the same record says only that they "will reopen spring 2027." The record's facility list gives May 6 through mid-October for showers, flush toilets and the dump station, without a year, so confirm 2027 service dates before an early-season trip. For 2026 the main campground, the walk-in and cart-in campground, the dump station, the campground shower building and the picnic shelter restrooms are all closed. For winter camping nearby, the Myre-Big Island State Park guide covers a park that offers it year-round.

Reservations are required for all campsites and can be made 120 days ahead. The DNR reservation FAQ says first-day bookings open at 8 a.m. Central and lists the reservation phone line as 866-857-2757. The Minnesota state park reservation guide covers the rest.

When to go

• Spring: the DNR describes the forest floor as a wildflower garden, with hepatica, bloodroot, Dutchman's breeches and the dwarf trout lily.
• Summer: the DNR suggests relaxing by Hidden Falls or taking a peaceful hike.
• Fall: red, orange and gold in the maple-basswood forest; the DNR lists "fall color" among the park's highlights.
• Winter: 4 miles of snowmobile trail, and snowshoeing anywhere except groomed trails and roped-off areas. The ranger station rents snowshoes.

A naturalist offers programs year-round, usually on weekends. The visitor center has flush toilets and a drinking fountain during open hours, and a red-handled water spigot on the north side of the visitor center runs 24 hours a day, year-round. Vault toilets near the picnic area and at the walk-in campground stay open.

Parking

The DNR warns that the main lot and overflow lot "fill up quickly," and suggests arriving early. Overflow parking is in the cart-in lot, a quarter mile west of the visitor center. If you are waiting for space, the DNR points to Caron Park, a county park 3 miles west.

Fees and permits

Every vehicle needs a permit. Cell service at the park is poor, so the DNR recommends buying online before you arrive and displaying the confirmation number, purchase date and permit type on your dashboard. Permits are also sold at the visitor center when it is open. From the DNR vehicle permit page and fee schedule, before tax:

Two nights at a cart-in site: 2 × $20 + $8 reservation fee = $48 at the low end, plus a vehicle permit ($7 overnight or $35 year-round). For multi-night stays, ask the park which permit covers your whole stay; the year-round permit covers every visit for a year. ReserveMN shows the exact rate for each site.

Getting there

The DNR's directions: take I-35 to State Highway 19 east into Northfield, go south on State Highway 3, east on State Highway 246, then turn right onto County Road 29. The nearest town is Nerstrand.

Other parks in the region include the Sakatah Lake State Park guide and the Rice Lake State Park guide. Browse all bluff country guides or the park finder.

Before you go

1. Buy your vehicle permit online at home; cell service in the park is poor.
2. Arrive early in the day; the main and overflow lots fill quickly.
3. Wear sturdy shoes for the stairs and roots on the Hidden Falls Trail.
4. Stay on trails and leash dogs to protect the dwarf trout lily.
5. Check visitor center hours; as of the DNR's October 19, 2026 update it is closed Monday through Wednesday.
6. Campers: book for April 30, 2027 or later, and check spur length.
