Portland, ME's best dog parks, from Quarry Run's wooded acres to the Eastern Prom.

Eastern Promenade, Mayor Baxter Woods, and the Western Promenade carry seasonal off-leash windows that typically run dawn to 9am and 5pm to dusk; the actual hours are posted at each park entrance and shift in the spring and fall. Quarry Run on Ocean Avenue is fully fenced and off-leash any time it's open. South Portland and Falmouth have their own ordinances; Hinckley Park (South Portland) is off-leash on the trail system, and Mackworth Island (Falmouth) is leashed-only with rangers on site.

Maine state law does the same on the rabies side. There's no entry fee or off-leash permit at any city park. Mackworth Island State Park charges $4 per non-Maine adult at the gate; Maine residents enter free.

The off-leash areas don't check vaccinations at the gate, but DHPP and bordetella are worth keeping current if your dog is mixing on the regulars circuit at Quarry Run or Valley Street.

December through March, fenced parks like Quarry Run and Valley Street stay usable but icy underfoot, and Valley Street's wooded hillside gets genuinely slippery. Mud season runs late March into early May. Summer is short and excellent: cool mornings, long evenings, and the off-leash hours line up with sunset over Casco Bay. Black-fly season hits the wooded preserves in late May and June.

Eastern Prom, Fort Sumner, and Back Cove ring the central peninsula. Mayor Baxter Woods sits in the Stevens Avenue corridor, with Capisic Pond just west of it. Hinckley Park is across the bridge in South Portland, Mackworth Island is the Falmouth pick, and the Westbrook and Kennebunk fenced parks cover suburban runs west and south.
