The South Portland Greenbelt is an off-road pathway enjoyed by thousands of residents and visitors each year who use it as a transportation way and for recreation purposes. The trail is 5.6 miles, between Wainwright Athletic complex near the Scarborough town line and the historic Bug Light Park, where Liberty Ships were built during World War II.
The trail is a city trail, travelling through neighborhoods and large street intersections. As a result there are many entry and exit points, not just the indicated trailheads. This paved path is generally 10-feet wide with 36” narrower sections near streets to prevent automobile access to the trail. The treadway has low slopes and crossslopes and seamless ramps for driveways and streets.
The trail treats walkers, runners, and cyclists to three distinct vistas of the Portland waterfront and wildlife watching along the trail is popular at many of the fields, wetlands, marshes, and woods passed along the route. Bug Light Park, the northern end of the Greenbelt Walkway, provides expansive views of Portland Harbor and, as a 9-acre park with a beach, offers a great picnic and walking spot.
The Greenbelt Walkway also functions as the northern end of the Eastern Trail, a 65 mile, multi-use greenway in development from Kittery to South Portland, and is maintained in collaborative effort of the City of South Portland and the Eastern Trail Alliance. Nationally the Greenbelt is also designated route for the East Coast Greenway that one day hopes to extend 3,000 miles from Key West, Florida to Calais, Maine.
Trail conditions can change without warning. Trail last assessed: 7/18/2026.

Recognize Working Forests and Waters: Maine’s landscapes are not just for recreation—they’re also active, productive environments that support local livelihoods and communities. Forests may be actively logged; waterways are used for lobstering, clamming, aquaculture, and transport. For everyone’s safety, maintain a safe distance from active logging operations, and do not disturb working docks, fishing equipment, traps or buoys.
The trail has three primary access points:
Wainwright Athletic Fields: Winwright Fields: Follow Highland Avenue south 2.6 miles from ME Route 77 in South Portland, and look for Gary Maietta Drive on the right. From Scarbrough, follow Highland Avenue 2.8 miles north from its intersection with ME Route 207. Follow Gary Maietta Drive until it ends at the Wainwright Athletic Fields' parking lot.
Bug Light Park: Follow Broadway to its northern end in South Portland. Turn left onto Breakwater Drive and then left onto Madison Street. Follow Madison Street into Bug Light.
Mill Creek Park: Mill Creek Park is at the intersection of Broadway and Ocean Street in South Portland just east of the Casco Bay Bridge. Parking is on the street around the park.
