Portland Harbor in Casco Bay is the northernmost port that does not freeze over in winter.  In its heyday Casco Bay was a large shipbuilding community.  Over time the bay has settled into a mix of working waterfront, tourism, and residential areas.  The bay is serviced by Casco Bay Lines, which has regularly scheduled ferries to Chebeague Island, Cliff Island, Great Diamond Island, Little Diamond Island, Long Island and Peaks Island.
