Osbornedale State Park

Osbornedale State Park combines woodland trails, pond scenery and geological features in Derby.

Osbornedale State Park

Its varied landscape offers an outdoor visit close to the Naugatuck Valley’s urban communities.

Choose a route from the current state-park map and check notices before setting out. The photograph highlights a large boulder in the park rather than every trail or visitor facility. The Osborne Homestead Museum and Kellogg Environmental Center follow their own opening and program schedules. Fishing, reserved shelters and winter activities have specific rules and conditions; use only authorized public areas.
