About Coleman State Park
Little Diamond Pond sits at the center of this 1,200-acre property, which the state bought from the Coleman family in 1956 after it had operated as Camp Diamond. Visitors can camp, hike, fish, ride ATVs, and picnic on the grounds. The land's history as a private camp before becoming public parkland shapes its current footprint and layout.
Hours, fees, camping, reservations and closures are set by the park and change often. Check the official park site before you go.
