You should always swim with a buddy, at a lifeguarded beach.
During the summer, Fire Island National Seashore provides opportunities for supervised swimming at two lifeguarded beaches, at Sailors Haven and at Watch Hill, which are both accessible by ferry or private boat.
With additional National Park Service (NPS) funding in 2008 and 2009, weekend lifeguard service has been added to Barrett Beach.
NPS lifeguarded beaches are normally staffed daily from late June through Labor Day weekend. Additional weekend days may be added before and after the summer season if staffing and weather conditions permit.
Several of the Fire Island communities also have seasonal lifeguarded beaches.
If you'd like to drive to a lifeguarded beach on Fire Island, try Smith Point County Park and Robert Moses State Park. Both have large capacity parking lots, changing rooms and showers, snack bars, and a small playground for children.
