Great Camping
We try and go there 3 to 4 times a year. This is a great state campground. You can't find no other one better than this one in the state of Ohio as far as I am concerned.

Boater & Camper
This campground is located on a Great Lake for boating and fishing. The campground has very nice sites,restrooms and they now added a beautiful swimming pool. The lake also has many restaurants that are accessible by boat. It is our favorite campground close to home!

Great Find!!!
Campground and staff are great. Splash pad for kids. Sites are big. Just the right amount of trees. Will camp here again.

St. Marys Pretty Good Place To Stay
Stayed on a Tues night so campground was almost empty. Wi Fi and solid surface pads make this a great place. Very quiet during week, but heard weekend was packed. You're right on the lake, but most views are blocked by rentable cabins. Boat dock & marina near and camp store has everything you forgot. Bathrooms were clean, plentiful and had soap (nice!). Staff was terrific! Thank you St. Mary's.
