Grand Lake Saint Mary’s State Park

Welcome to Ohio's beautiful Grand Lake Saint Mary's State Park. Grand Lake Saint Mary's was the world's largest reservoir at the time it was built and it's primary purpose was to feed water into the Miami and Erie Canal. This park is, needless to say, a great place for water recreation and there is no horsepower limit on the lake. The lake is full of bass, bluegill, carp, catfish, perch, and walleyes. Come out and do a little fishing or water-skiing.

Camping: The campground at Grand Lake Saint Mary's State Park has many campsites. Some of them have full hookups and some of them are primitive. Come out and stay a few nights.
