The second largest contiguous land holding of the State of Vermont, Groton State Forest protects 26,000 acres of forests, ponds and bogs. Visitors can enjoy dispersed recreation on trails and at campsites and campgrounds throughout the forest.
The Nature Center provides access to trails south of Osmore Pond including a nature trail and the Peacham Bog Loop. Hikers can also connect north to access Osmore Pond and Big and Little Deer Mountains.
Groton Nature Trail - This self-guided nature trail travels through diverse woods. An accompanying trail guide booklet is available at the Nature Center and at the Stillwater State Park Office.
Little Loop Trail - A short loop that includes a short spur to an overlook of a wetland. The Little Loop trail also provides access to the Peacham Bog Loop.
Peacham Bog Loop - Leaving from the Little Loop Trail, this longer, moderate trail travels through many forests types and past a beaver dam. Two miles east of the Little Loop Trail, there is a short spur to a viewing platform on the Peacham Bog, one of the largest bogs in Vermont. Please use caution at the bog as the vegetation is fragile and sensitive to trampling. In order to make a loop, hikers need to turn right onto Coldwater Brook Road on their return, the left where Peacham Bog Loop crossed the road.
Hosmer Brook Trail - This trail follows Hosmer Brook north toward Osmore Pond and goes over some rocky sections. From the intersection with the Osmore Pond hiking loop, hikers can access trails for Big and Little Deer Mountains or hike around Osmore Pond.
