Sebago to the Sea Trail

Sebago to the Sea Trail is a 28-mile pathway that goes from Sebago Lake, weaving its way in tandem with the Presumpscot River.

The Sebago to the Sea Trail is split into seven sections, with Section 1 staring at the lake and Section 7 ending at Casco Bay at the Eastern Promenade and the dog-friendly East End Beach.

Knowing the Sections & Safety

Each section brings benefits and potential risks, but it starts with knowing how much of a hike your dog can handle. Always keep your dog on a leash and pick up all waste as you go. Don't bag and drop waste.

Section 1: Sebago Lake to Route 237

Keep your dog on a leash and out of the water, as this portion of Sebago Lake is under strict "Bodily Contact Prohibited" restrictions for the Portland Water District (PWD) intake.

Be sure to fill out a PWD Permit at the trailhead.

Section 2: Route 237 to Otter Ponds

Another PWD Permit is required on this stretch of land that goes through the woods and by the popular fishing holes of Otter Ponds.

Follow the sign guidance for dog access to the ponds, but plenty of people let their dogs off leash here. You should use extra caution before considering it since lakes like this can grow toxic blue-green algae that are especially dangerous to dogs.

Section 3: Otter Ponds to Route 202

This paved section of trail runs 4.5 miles through the mountains before crossing over the Presumpscot River. This trail also goes near Gambo Preserve.

Section 4 & Section 4a: South Windham to Westbrook and Downtown Westbrook

The walking trail gets rugged here along railroad trails, and paws should be checked occasionally for rocks or cuts. You can also pick up part of the paddling trail here.

You can also stroll through Downtown Westbrook or get a bite to eat.

Section 5: Westbrook to Route 302

This trail is a mix of roadside walking and off-road trails, but also subject to seasonal flooding or impassible trails during mud season.

Section 6: Route 302 to Blackstrap Road Canoe Launch

Wooded trails meet Riverside Street, which can make for some nerve-wracking interactions with traffic on the road prone to speeding and with limited sight lines. You're in Portland on most of this trail.

Section 7: Blackstrap Road Canoe Launch to East End Beach

Off-road and wooded trails guide you through the wilderness, into city parks, and on some sidewalks before crossing the bridge between Casco and Back Bay.

The trail ends at the Eastern Promenade near Portland's downtown and Old Port areas.

Sebago to the Sea Trail Water Quality

Check the water quality along the river to see the historically more polluted or unhealthy parts of the path. Do not let your dog drink any freshwater sources along the way, even if it looks clean. Bring your own supply.
