Ahern State Park
Explore a wooded park with trails and shoreline along Lake Winnisquam.
Before you go
The park is typically unstaffed. In winter the gate closes, parking is not plowed, and facilities are unavailable; walk-in access is permitted unless posted otherwise. Camping is prohibited. Pets are permitted on trails, not the beach.
