The spot
The things that stay true when the weather changes.
Swim in the guarded season, late June through Labor Day, when lifeguards are on duty at the seashore beaches.
Beach lots with seasonal fee booths. From mid-June to Labor Day the Coast Guard Beach lot is limited to Eastham residents and placards, so visitors park at Little Creek and take a short shuttle.
