This is a popular public barrier beach known for its consistent breezes, making it a popular spot for windsurfer, kiteboarding and watching the boats and ferries head into Hyannis Inner Harbor.

The beach is owned by the town of Barnstable and is located at the end of Ocean Street, separating Lewis Bay from Nantucket Sound. It features both ocean-side and bay-side areas, with a long jetty that separates the two.

Recreation and environment
  • Two distinct sides: The beach is split into sections. The ocean side has some small waves and is more exposed to wind, while the bay side is calmer with tidal pools, making it great for families with younger children.
  • Windsurfing: Steady winds make this a “windsurfing haven,” and there is a designated area to accommodate the sport.
  • Boating views: Visitors can sit on the jetty and watch ferries and other boats traveling in and out of Hyannis Harbor.
  • Shells and seaweed: The shore is lined with shells, which can keep young children entertained, but seaweed can sometimes be an issue.
  • Conservation area: The beach is part of a wildlife area and has been used to deposit sand dredged from a nearby channel, creating habitat for beach-nesting birds.
Facilities and amenities
  • Seasonal snack bar: A snack bar is typically open during the summer and sells items like seafood and other food and drinks.
  • Restrooms and showers: The beach has bathhouse facilities with restrooms and outdoor showers, which are open seasonally.
  • Lifeguards: Lifeguards are generally on duty from late June through Labor Day.
  • Accessibility: Accessible features include a beach wheelchair, accessible parking, and accessible entrances to the bathhouse.
