Deer Lake State Park Near Rosemary Beach, Florida

The Northwest coast of Florida is best known for its white sand beaches and Spring Break party destinations. But just off of Highway 30A lies a rare coastal dune lake.

Coastal sand dunes themselves are somewhat of a rarity but coastal dune lakes are extremely rare. There are only five places in the world where these exist ( New Zealand, Australia, Madagascar, Northwest Florida and Oregon). The dune lakes in New Zealand and Northwest Florida are the rarest.

What is a Coastal Dune Lake?

The coastal dune lake at Deer Lake State Park is considered one of the rarest in that it periodically blows out into the gulf, mixing fresh water and the salty gulf ocean water. This mixing of the waters provides eleven distinct natural habitats within Deer Lake State Park; swamp, marsh, estuarine tidal creek, depression marsh, basin swamp, beach dune, scrub, sandhill, coastal dune lake, blackwater stream and estuarine tidal creek. The ecosystem created by this meshing of the waters also provides a delicate habitat for migratory birds, butterflies and loggerhead turtles and is home to rare plants such as spoonflowers and curtis sand grass.

Ocean Access and Boardwalk at Deer Lake State Park

In 2004 State of Florida Department of Environmental Protection constructed a mile long boardwalk over the dune that leads to the ocean at Gulf Coast Beach in Deer Lake State Park. This boardwalk offers great views of the dunes themselves and of the dune lake. Animal tracks from coyotes, bobcats, fox and raccoons are visible in the sand indicating the plenitude of wildlife that exists within the park. The park boasts over 1920 protected acres and offers beach access, picnic area and fishing. There are no facilities so be sure to bring food and drinks.
