Grayton's beach rules, each with its authority
Four systems govern the sand here: the South Walton Fire District's flag system for swimming, Walton County Code Compliance's resident-only permits for beach driving and beach dogs, the fire district's permits for bonfires, and Grayton Beach State Park's own rulebook inside its boundaries. Every rule below names and links the agency that runs it, because a rule without an authority is just a rumor with confidence.
Criteria, printed: this page states only rules whose operating authority we can name and link. Where a detail lives with an agency and changes on their schedule, fees, hours, seasonal specifics, we link the agency instead of freezing a number here. If a rule you have heard about is missing, that means we could not source it, not that it does not exist; ask the agency, not a stranger's forum post.
Swimming: the flag decides, not the vibe
The Gulf here runs on the South Walton Fire District's beach flag system: double red means the water is closed, single red is high hazard, yellow is medium hazard, and purple warns of dangerous marine life. The flag is the first thing locals check and the last word in every argument. On a red-flag day the town does not sulk; it moves to Western Lake, the galleries, and the porch, which is why nobody here treats a red flag as a ruined day.
Driving on the sand: residents only, and famously so
Grayton is one of exactly two beach accesses in Walton County where permitted vehicles may drive the sand, per 30A.com's permit guide, the other being Inlet Beach. The permits are issued by Walton County Code Compliance through an annual lottery restricted to county residents, property owners, and registered voters, at $135 for one year with a current 4x4 registration, applications opening in April. There is no visitor version. The trucks you see are the town's oldest habit operating inside a modern rulebook, and our full guide tells that story properly.
Dogs on the beach: a resident permit, not a leash question
Walton County allows dogs on its beaches only under a permit limited to county real property owners and permanent residents, issued by Code Compliance with a current rabies certificate in the applicant's name. That means a visiting dog, however nice, does not have a legal path onto the sand, and the town's famous slogan does not override county code. Cottage porches, sandy lanes, and legal walks keep visiting dogs busy; the beach itself belongs to permitted locals.
Bonfires: the fire district's paperwork, then the marshmallows
Beach bonfires are permitted through the South Walton Fire District: the permit holder must be 18 or older and present, a standard permit covers gatherings of fewer than 30 people, larger groups also need a Walton County Outdoor Special Event permit, approved containers max out at 4 feet, and ashes must be doused and removed. The county tourism bureau lists 30A Blaze as the local hosted-bonfire operator for households that would rather outsource the paperwork with the s'mores.
The park is its own country
Grayton Beach State Park runs on Florida State Parks rules, not county ones, and its entry, camping, and activity details live on the park's official site. When in the park, the park's word governs; when on the town's sand, the county's and the fire district's do. Knowing which flag you are under, literally and legally, is the whole trick of doing Grayton correctly.
