South Walton County is home to some of the most sought-after white sand beaches in Florida, and public access to them is unusually abundant for a coastline this desirable.
Topsail Hill Preserve State Park
About 2.5 miles from Mack Bayou, Topsail Hill Preserve offers three miles of white sand beach backed by dune lakes, pine flatwoods, and scrub habitat. It’s one of the largest and most protected stretches of coastline in South Walton County, with designated parking and boardwalk access to the beach.
Grayton Beach State Park
Grayton Beach State Park adds another mile of pristine white sand beach across roughly 2,000 acres of coastal dune lake and forest habitat. It’s consistently ranked among the best beaches in the United States, and its proximity to Mack Bayou and The Preserve makes it an easy trip for property owners in the area.
Old Highway 98 beach access points
Beyond the two state parks, numerous public beach access points line Old Highway 98 through Santa Rosa Beach, Blue Mountain Beach, and Grayton Beach. Most offer parking, dune walkovers, and restrooms, giving residents and visitors easy, low-traffic ways to reach the Gulf without needing a resort or rental to do it.
Blue Mountain Beach and Seagrove Beach
Just up the road from Grayton Beach, Blue Mountain Beach and Seagrove Beach add still more public access points, each with their own character, from Blue Mountain’s namesake dune to Seagrove’s quieter, less commercial stretch of coastline.
Why this matters for waterfront buyers
For anyone considering waterfront land on Mack Bayou, this level of beach access means the Gulf is never far, even while living on the calmer, more protected waters of Choctawhatchee Bay.
