The spot
The things that stay true when the weather changes.
Hilton Head's official beach season runs April 1 through September 30, when lifeguards staff Coligny's designated swim area. Shore Beach Services flies the town's red, yellow and purple warning flags from March through October: red for rough conditions, yellow for moderate to light, purple for jellyfish, stingrays or other dangerous marine life.
Free at the main lot off Pope Avenue, the only town beach park with no parking fee; 8 ADA spaces there and 8 more at the 1 Coligny Circle lot. Every other town beach park charges $3 an hour on weekdays and $5 an hour on weekends.
