According to Leatherman, visitors to Beachwalker Park sometimes get upset about the murky water. "This is just the nature of the South Carolina coast," he explains. "The water's clean, but it's not clear because of all the marshes and the big tides they have there." Dark as it may be, the water stays in the low- and mid-80s year round, making it perfect for swimming.

Beachwalker Park is Kiawah Island's only public beach, and lifeguards are on duty in the summer. When you're done swimming, explore the island’s wildlife on canoe or kayak.
