Lakes that breathe with the Gulf
Most people come to 30A for the white sand and green water. The odd thing about this stretch of Walton County is what sits just behind the dunes. Visit South Walton counts 15 coastal dune lakes here, a landform so uncommon that the county's tourism office lists only New Zealand, Australia, Madagascar and the United States as places to see them.
The lakes were shaped by wind and waves over thousands of years, and they never sit still. They average about five feet deep, ringed by dunes up to 30 feet high. When rain and creek water fill one, the lowest point of the beach gives way. Locals call it a blow out. Lake water rushes to the Gulf through a temporary outfall, salt water washes back in, and in time the sand seals the gap.
That push and pull keeps the water brackish and the life inside it varied. Fallen leaves and other organic matter steep in the lakes and stain them a copper brown, like strong tea, which looks odd next to the turquoise surf but feeds an unusually rich habitat. Western Lake, beside WaterColor, is the one most visitors paddle, and Grayton Beach State Park and Topsail Hill Preserve State Park both reach the shore of a lake. Anglers fish them for salt and freshwater species alike, depending on how recently a lake last opened.
Seaside, and the way 30A shops for supper
The food side of 30A starts in Seaside. Robert Davis inherited the land from his grandfather in 1978, and building began in 1981 with two houses, one street and a beach pavilion. The town now counts more than 300 homes plus restaurants, shops and galleries, and its compact center is where much of the road comes to eat.
On Saturday mornings the Seaside Amphitheater fills with the farmers market, rain or shine, from 9 AM to 1 PM. It is a producer's market: local growers, bakers, cheese makers and gardeners, with cooking demonstrations and seed swaps in the mix. Airstream Row, the line of food trucks parked in silver trailers, sits right beside it. Buy vegetables at one end, a late breakfast at the other.
Hurricane Isaias came ashore near Destin on October 9, 2026, as a Category 2 storm. Walton County Tourism reported on October 16 that many businesses had reopened while some amenities stayed limited, so check its update page before a fall trip.
