Grayton Beach: The 30A Park With a Rare Coastal Dune Lake

At Grayton Beach, two kinds of water meet in a way you will see almost nowhere else: a tea-colored freshwater lake sits just behind the dunes, sometimes breaking through the sand to pour into the emerald Gulf. It is called a coastal dune lake, and Florida’s Panhandle has most of the world’s supply.

A Beach Worth the Hype

Grayton Beach State Park sits along scenic Highway 30A in Walton County, in the stretch of the Panhandle known for sugar-white quartz sand and clear green water. The sand here is so fine it squeaks underfoot. In 1994 the beach expert known as Dr. Beach ranked it the best beach in America, and it has stayed a favorite ever since. Behind the dunes lies one of Florida’s last undeveloped stretches of coastal scrub.

The Rare Dune Lake

The park’s signature feature is Western Lake, a coastal dune lake. These shallow lakes form behind the dunes and occasionally connect to the Gulf through a temporary outlet, mixing fresh and salt water in a way that supports unusual plants and animals. Only a few regions on the planet have them, and South Walton County holds about fifteen. You can paddle the lake, then walk a few steps over the dune and swim in the Gulf, two completely different worlds side by side.

Plan Your Visit

Grayton Beach State Park is open year round and sits between Destin and Panama City Beach off 30A. There is a campground, miles of trails through the scrub, and kayak and paddleboard rentals for the lake. Mornings are quietest and best for the water. Bring sun cover for the open beach, and take time to notice the dune lake, a quiet natural wonder hiding behind one of the prettiest beaches in the country.
