Winthrop Beach is the main beach of Winthrop, Massachusetts. It is located along Winthrop Shore Drive, spanning the roadway. The beach begins off Crest Ave. at an area known as the "Green Bars", named for the green railings along the seawall. The beach ends at the base of Water Tower Hill. The ocean has five wave breakers called the "Five Sisters" off shore to protect nearby neighborhoods from the large swells that occur during storms.
Winthrop Beach is open year round to the public from dawn to dusk and is noted by some as the "centerpiece" of this community.
