Coastal Dune Lakes

The one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us."

There are many aspects that make the Coffeen Nature Preserve unique, but perhaps the greatest one is Lake Fuller.

Coastal dune lakes are quite rare. There exist only about 25 in the world, and 15 are located here in Walton County.

Why are they so rare? What makes them so different? The only other places on earth where dune lakes appear are New Zealand, Australia, Madagascar and on the Pacific Coast of the United States.

Lake Fuller rest quietly near the western end of scenic highway 30A within the pristine boundaries of the Coffeen Nature Preserve. Located in the Sandestin area between Tops’l resort and Topsail Hill Preserve State Park, the 40-acre lake is fed by rainwater and groundwater seepage and is known as one of the most beautiful of the dune lakes. Lake Fuller maintains its unspoiled environment due to less human traffic and activity than most of the lakes.
