Grand Lake St. Marys State Park Campground Reviews
We love it there the people are very nice and incredible views of the lake great new pool and grounds are kept clean
Jun 27, 2025 · John HeslerBeautiful and well-kept campgrounds that are fully equipped with everything you could want and a lot of stuff you don't need.We are primitive campers, so we just had a couple of tents, but we did enjoy the showers - which are rather clean (full of spiders, but that's normal for camping, and those guys gotta get clean, too). Just be sure to bring your own soap.You can't swim in the lake due to some kind of algae bloom, but there is a pool and a splash pad to get you wet.
Jul 12, 2024 · Greg EakinsWe had a wonderful stay at the Grand Lake St. Marys State Park Campgrounds. We got on line reservations and had a great site right on the water. The campgrounds and facilities were well kept and clean. The site was a level paved pull thru site with electric hook ups, a fire ring and picnic table. The campgrounds are pretty much open but were quiet and they had a pet park, playgrounds, picnic shelters, and docks for guest use. We had a nice relaxing stay.
Oct 08, 2023 · ray weithmanNice campground. Most loops have nice shade over most campsites. Full hookup loop is a little lacking in shade but still nice. Sites are large with plenty of space.
Jun 26, 2025 · Fred Albert1st. Visit to an Ohio state park campground. This place is very well kept up. Sites are not on top of each other. We had full hook-up for our 7 day stay. Beautiful lake, very quiet, laundry room, shower room, Wi-Fi, pool, walking trails, and close to town. Plan to return.
