About

Brunet Island State Park occupies an island between the Chippewa and Fisher Rivers near Cornell, with swimming, boating, and fishing on both channels. The South Campground has 24 electric sites and a shower building; the North Campground's 45 non-electric sites sit along the Chippewa River shoreline. One site is wheelchair-accessible.

Fees

Wisconsin DNR statewide camping system: a vehicle admission sticker is required at every state park or forest entrance, including for registered campers - $28/year for Wisconsin residents ($13/year age 65+) or $50/year for non-residents, or $13/day resident / $16/day non-resident. Nightly campsite rates vary by electricity, amenities, location, site type, day of week and season, and are shown when you select a specific site during booking; non-resident campers pay a flat $15/night surcharge on top of the site's own rate. A $9.30 reservation fee applies per booking, plus a $10 cancellation fee or $6 change fee if plans change. Pets are allowed at this campground on a leash no longer than 8 feet at all times, per Wisconsin State Park System's statewide pet policy; owners must clean up and properly dispose of pet waste.
