Went to Maine for salt and sand.  Stayed in Small Point, at the intersection of the Sprague River and Seawall Beach.  Seawall Beach is all sand, a pristine stretch about two miles long (and at low tide almost as wide) bordered by two tidal rivers.   There is no easy public access to this beach.  A handful of Small Point residents can cross the Sprague River at low tide to walk on the beach, and at low tide, beach-goers can cross the Morse River at the other end of Seawall at Popham Beach State Park.   One can also traverse a two-mile trail through the 500-acre Bates Morse Mountain Conservation Area to get to the beach.   Needless to say, in late June the beach was practically empty.   I don’t know a prettier beach in all New England!  Our isolated rental cottage sat just above the Sprague with an ever-evolving view.
