This park shares its name with the coastal dune lake within its boundaries. Coastal dune lakes are extremely rare worldwide and in the United States they occur only along the Gulf Coast. Southern magnolias, golden asters, woody goldenrod, and scrub oaks can be seen in this coastal dune habitat. Rare plants such as gulf coast lupine, spoonflower, pitcher plants, and Curtiss' sand grass-one of the largest populations found in Florida-are found in the park. Visitors may see splashes of color from summer wildflowers or some of the many species of resident or migratory birds and butterflies. A boardwalk across the dunes offers easy access to the beach where visitors can picnic, swim, and fish. It also offers a spectacular view of the dune ecosystem, one of 11 natural communities found in the park.
