Boaters seeking a lakeside base camp can access Grass Lake Marina and RV Park only by water, making it a unique destination for those already on the Chain O' Lakes system. This no-frills facility provides electric hookups, including 50-amp service, along with water connections and periodic black water pumping service at individual sites.
The campground features a large mowed field where dogs can run off-leash, and the lake provides swimming opportunities for pets. Bald eagles nest in the area, offering wildlife viewing from campsites. The marina setting puts campers directly on the water with immediate boat access. Staff members receive positive mentions from visitors for their helpfulness. For land-based camping alternatives, Chain OLakes State Park Campground sits just across the water.
