Located in the Rainier Beach area, north of Beer Sheva Park. Several large cottonwoods flutter in the breeze as swimmers head for the raft, where they spring into the air from high and low diving boards. Others just sit on the beach admiring the view of Seward Park to the north and Mercer Island to the east. You’ll find this a fine, quiet complement to the Atlantic City beach to the south,since there is no boat ramp ruckus here.
