Father Hennepin State Park

This guide is for campers comparing Mille Lacs Lake campgrounds and for day visitors planning a swim, a picnic or a few hours of shore fishing. It covers the campgrounds, trails, seasons, what you pay and how to get there. Facts come from the Minnesota DNR park page, the DNR park map and the DNR fee and reservation pages, listed at the end.

The park in brief

The DNR park page describes a mostly mixed hardwood forest with pockets of pine, bogs and swamps, and trails that run "through a hardwood forest and along the rocky shoreline of Mille Lacs Lake." The DNR park map says the park was established in 1941 "to allow public recreation on Mille Lacs Lake."

The park is small. The DNR feed lists 325 acres, while the DNR narrative and park map both say 344 acres. It is named for Father Louis Hennepin, a priest who visited the area in 1680 and stayed with the Dakota for six months. The DNR notes he "is not thought to have been in the exact location of the park."

The DNR lists the park's albino deer among its highlights, and its wildlife notes say hawks, ospreys, owls and eagles are common.

Camping at Father Hennepin

The park has two drive-in campgrounds, Lakeview and Maple Grove, plus group camping. Reservations for either campground include access to a shower building in the center of that campground during the open season.

The DNR's camping listing counts six seasonal group sites; the park introduction mentions "two group camps" and the park map "a large group camp," so check ReserveMN for the current layout. The DNR's seasonal update says the Group Camp is rustic, with pit toilets and a hand pump for water, and its campers do not have access to showers. Group sites close at the end of October. Docks in Lakeview Campground are for campers only.

Reservations: the DNR says that for summer "it is highly recommended that you have your reservation before traveling," and you need a reservation before you can occupy a site. Sites open on ReserveMN 120 days ahead, and the DNR reservation FAQ says that on the first day a date opens, online booking starts at 8 a.m. Central. The state park reservations guide walks through the system. If you have a very large RV, the DNR asks you to check that it fits the site driveway; site lengths are listed on the reservations page.

Trails, beach and fishing

The DNR feed lists 4.5 miles of hiking trail, including a 0.75-mile accessible trail. The DNR park map names three routes:

For a short visit, the DNR suggests walking the shoreline trails. The park map calls the quarter-mile sand beach "the best designated beach on Mille Lacs Lake," and the playground and volleyball courts are on the beach (pick up volleyball equipment at the ranger station). There are two picnic areas, Lakeview and Beach; the Lakeview enclosed shelter has a fireplace, electricity and a deck over the lake, and you call the park to reserve it.

Fishing: the park map suggests casting for northern pike, smallmouth bass, muskie or walleye from one of the two fishing piers. It also warns that Mille Lacs fishing regulations "are often changing," so check at the park office or the DNR fishing regulations page before you go. Mille Lacs Lake is a designated infested water, so inspect your boat before and after launching.

The ranger station lends birding kits and kids discovery kits (for ages 5 to 12) free, and an all-terrain track chair can be reserved for designated trails.

When to go

As of November 2026, all three campgrounds (Lakeview, Maple Grove and the Group Camp) are closed for the season. The DNR's seasonal update gives these spring 2027 dates, while the park alert (updated November 1, 2026) says more generally that campgrounds reopen "starting in late April, 2027":

The November gate: the DNR alert (updated November 1, 2026) says day use and foot travel are welcome year-round, but a locked gate restricts vehicle access to much of the park starting November 15. Once it closes, park in the turnaround in front of the residence and walk in. The alert says the gate reopens in spring "after sufficient snow melt." In winter the ranger station is closed and roads are unplowed, and the park "is open to foot travel only." Snowshoeing is allowed anywhere in the park, and vault toilets stay open year-round.

Water in the campgrounds, picnic areas and dump station was shut off October 19, 2026. Drinking water is available only at the shop building in the off season, and the DNR suggests bringing your own. ATVs, UTVs and non-street-legal dirt bikes may not be operated in the park and must stay on a trailer.

In summer, the DNR says interpretive programs run on most weekends.

Fees and permits

From the DNR vehicle permit page and fee schedule. The fee schedule says tax is additional on camping fees:

Two nights at an electric site, booked online: 2 × ($20 + $10) + $8 = $68 at the low end, or 2 × ($35 + $10) + $8 = $98 at the high end, before tax and plus a vehicle permit. ReserveMN shows the exact site price. Firewood is sold at the ranger station or through Yodel; gathering it is against park rules.

Getting there

From Isle, go one mile west on Highway 27 to the park entrance. Isle is the nearest town. The park is part of the Minnesota lakes country guides. Mille Lacs Kathio State Park is on the Rum River, which the DNR says flows from its source on the southwest shore of the same lake. Use the park finder to compare other parks.

Before you go

1. Book a campsite before you drive up in summer; you need a reservation to occupy a site.
2. Buy your vehicle permit online or at the ranger station or entrance kiosk.
3. After November 15, plan to park at the turnaround and walk in.
4. Check current Mille Lacs fishing rules; they change often.
5. Off season, bring your own drinking water.
6. Check for wood and deer ticks after hiking, as the park map advises.
