Carson Beach is located off William J. Day Blvd. in Boston, Massachusetts. Witha family friendly set up, Carson Beach has limited crowds, gazebos that cast cooling shade, clean bathhouses, food onsite, and Joe Moakley Park across the street. Much of the sand seems to have been imported which causes a muddy lake-like footing during low-tide and slightly less during high-tide. The sand is on the rocky side and has many bits of broken shell that haven’t been smoothed down by the water.
