Union Grove State Park Campground

Fishing enthusiasts will find Union Grove State Park Campground positioned along a lake known for quality angling opportunities. The DNR-managed facility operates seasonally from May through September, accommodating RVs up to 50 feet with full hookups including electric, water, and sewer connections.

The campground maintains a quieter atmosphere with most sites designed for RVs, though several smaller tent sites occupy the back section. Site conditions vary significantly—some feature uneven terrain with sloped picnic tables and awkward trailer positioning due to inclines. Campers can access lake activities including swimming and paddling, while hiking trails provide land-based recreation. The facility includes shower and restroom combinations, with one ADA-accessible unit, plus amenities like a lending library and dump station.
