The Sebago to the Sea Trail project was developed as part of a visioning session of the Presumpscot River Watershed Coalition, which formed the Sebago to the Sea Coalition in 2007. The Coalition is facilitated by the Presumpscot Regional Land Trust. The Sebago to the Sea project is a collaborative initiative, strengthened by its many partners and advisors.

Trail Route:

The Sebago to the Sea Trail is approximately 28 miles beginning at Sebago Lake and ending at Casco Bay, following the path of the Presumpscot River much of the way.

In October 2010, the first 8.5 miles of trail were designated from Sebago Lake to South Windham. This section includes 4 miles of trail on the Portland Water District's Sebago Lake Land Reserve and 4.5 miles of the paved Mountain Division Trail, a 10-foot wide bicycle and pedestrian trail along the Mountain Division Rail Corridor. In October 2011, 13 more miles of trail were designated making a complete trail from Sebago Lake in Standish to the Maine Turnpike in Falmouth. In October 2012, two more sections where designated: the remaining trail from Falmouth and Portland and a paddling section from South Windham to Westbrook while rail construction was underway.  In fall 2015 Section 4 from South Windham to Westbrook opened for pedestrian use while the railbed remains inactive.


The Sebago to the Sea Trail enhances a variety of natural and recreational resources in this growing suburban area and helps link the City of Portland to the shores of beautiful Sebago Lake. Much of it is accessible for off-road bikes, and some of it is accessible for commuters on bicycle and people of all abilities.

In addition to creating a regional trail, this project also:

  • promotes greater land conservation and public access

  • enhances watershed protection efforts along the Presumpscot River

  • connects a network of green spaces and trails in southern Maine

  • increases opportunities for healthy outdoor exercise

  • raises awareness of the cultural heritage of the area including the Cumberland and Oxford Canal , the Mountain Division Rail Line and the native Abenaki people

  • provide public awareness of existing trails and projects in the Presumpscot River Watershed

  • generates visitors and economic activity

  • strengthens collaborative partnerships within the Presumpscot River Watershed to enhance future efforts benefiting the region
