Maquoit Bay is a shallow, tidal bay on the upper reaches of Casco Bay near Brunswick, Maine. Its waters are tranquil and mellow, with a soft, southern shoreline characterized by eel grass and egrets. The bay is tide-dependent for paddling, with thin waters that become extensive clam flats at low tide. Paddlers are advised to use the top half of the tide for exploration. The primary public launch for the bay is Wharton Point, also listed as Maquoit Landing, which is a half-tide gravel launch site. Two other older launch ramps in the area, at Simpson Point and Lookout Point, are being significantly limited. A deeper-water alternative is the Mere Point Boat Launch, which provides all-tide access to the northern part of Casco Bay approximately six miles from Brunswick's south end. The bay's shallowness results in a dearth of lobster traps and larger boat traffic, though keeled yachts can anchor in the deep channels. Notable destinations within the bay include the Maquoit Bay Conservation Land, a 124-acre preserve with a trail leading to Rocky Point, a rocky promontory offering coastal vistas and a place to swim in the warm, shallow bay at high tide. The preserve features freshwater streams transitioning to saltmarsh, providing significant habitat for wading birds and waterfowl. Crow Island, managed by the Harpswell Heritage Land Trust, is another quiet destination for picnicking and birding. Paul's Marina on the bay offers a dock-and-dine opportunity for boaters. The area is popular for birdwatching, and wildlife sightings include great blue herons, egrets, and various waterfowl.
