Otsego Lake is a great campground. It's quiet for a state park, and the sites are roomy. The sites on the outer perimeter have large trees and some have water views. The lake is clean, and in addition to the main beach there is a dog beach and multiple access points away from the crowds. The bathrooms were older but clean and well-maintained. 

There is some easy hiking on the other side of the lake, at Pine Baron trails. We also enjoyed going to nearby Gaylord for mini golf, restaurants, and an elk park.
