Back Cove, Portland, Maine
Back Cove is an estuary basin on the northern side of the City of Portland, Maine's downtown district. It is nearly circular and about one mile in diameter. A popular loop trail runs around the circumference of the cove. Being tidal, Back Cove dries out to mud flats at low tide and is not commercially navigable. It is sometimes incorrectly referred to as Back Bay. Its mouth is crossed by Interstate 295 on Tukey's Bridge.
