Please note that Mainstone Farm is privately owned. Portions of the land are not open to the public. Please stay on designated trails, shown on the map.

Hamlen Woods and Mainstone Farm highlight a complex of conserved lands owned by the Town of Wayland, Sudbury Valley Trustees, and other private entitites. Additional protected lands, including Mainstone Hills, Reeves Hill, and Turkey Hill contribute to a network of wildlife habitat and public trails.

Trails are open for passive, public recreation. They are managed cooperatively by SVT and the Town of Wayland.

The trails are marked with colored diamond-shaped signs, indicated by the corresponding colored lines on the map. The blue trail will lead you from the Hamlen Woods parking area, north to Reeves Hill Conservation Land, over a one-way route of approximately 1.75 miles. The red trail will take you on an approximately 4.5 mile circuit through all of the connected areas. Use caution while walking Rice Road if you plan to link your walk between the Mainstone Farm parking area and Turkey Hill Road.
