Sullivan's Island allows free parking along the public rights of way, as long as the area is free from "No Parking" signs. There is additional parking near Battery Jasper and a little further down near Fort Moultrie.
Please be mindful not to block any of the residents' access to their driveways or homes.
Vehicles must have all four tires off of the roadway at all times. It is also illegal for vehicles to park or block beach paths. This includes golf carts.
