Mackworth Island

Ride Description

Mackworth Island is a legislated bird sanctuary and is connected to Falmouth by a causeway at the mouth of the Presumpscot River. It is the former home of James Phinney Baxter and of his son, Governor Percival Baxter, and was deeded to the State of Maine in 1943. Currently it is the site of the Baxter School for the Deaf.

The island is open to pedestrian visitors from dawn to dusk. The perimeter path is maintained by the Maine Bureau of Parks and Lands and is to be used for foot traffic only. Cycling on the perimeter path is NOT allowed. An outhouse is also available in the parking lot. This easy trail circles Mackworth Island and offers excellent views of Casco Bay. The trail surface is wood chips and packed soil, which may be slippery when wet, but the terrain is generally level, with moderate slopes not exceeding 10%. Small side trails follow steep slopes to the shore and may be inaccessible to some visitors. A new staircase with handrail has been added to a side trail on the south side of the island.

Please note this trail is managed by the state of Maine. There is a small fee to use it. For more information, visit the state park website:
