Coleman State Park, State park in Stewartstown, United States.
Coleman State Park sits along Little Diamond Pond in northern New Hampshire, featuring thick forests and water views that surround the entire property. The grounds include 29 campsites designed for different visitors, with separate sections for vehicle use and regular camping.
The park was created as a recreation destination and became an important spot in Coos County over time. Its role gradually expanded to support outdoor activities across all seasons, from water-based pursuits to trail use.
Fishing traditions live on at Little Diamond Pond, where anglers spend time catching trout throughout different seasons in a setting that feels genuine and unhurried.
The park is open year-round, though conditions change dramatically from season to season. Visitors should prepare for the weather in advance and bring proper gear, especially during colder months when snow and ice reshape the landscape.
This park connects to more than 600 miles (965 kilometers) of trails throughout Coos County, making it a hub for snowmobile and off-road routes that stretch far beyond the property. That vast trail network lets visitors explore surrounding terrain for hundreds of miles without leaving the regional system.
