Gulf County Florida map | Port St. Joe and Wewahitchka

A Gulf County Florida map is organized by an inland highway connecting two very different water landscapes. Port St. Joe, the county seat, faces St. Joseph Bay in the south; Wewahitchka lies by Dead Lakes and the Chipola River system in the north. State Road 71 links them across a long middle of forest, wetlands, White City, and Dalkeith rather than through a continuous coastal settlement.

From Port St. Joe, U.S. 98 reaches west through beach communities, 30A and 30E branch toward Indian Pass and the St. Joseph Peninsula, and SR 71 heads north to Wewahitchka. The Apalachicola floodplain closes much of the east. Bays, rivers, and the narrow peninsula make straight-line proximity unreliable unless an actual bridge or paved approach is also identified.

Place names represent different layers. “Port St. Joe” can be the mailing city for an address far down the peninsula, while Mexico Beach belongs to Bay County despite its continuity with Gulf County’s western beach corridor. Municipal limits, postal labels, and coastal destination names should never be treated as interchangeable.

The Census Bureau reports 14,192 residents in the 2020 Census, 553.45 square miles of land, and a density of 25.6 people per square mile. Its July 1, 2025 estimate is 15,943, 12.3% above the 2020 estimates base. The low density explains the broad forest, wetland, and floodplain intervals separating the two cities and smaller communities.

FIPS 12045 is the federal identifier for Gulf County in tables and many GIS downloads. The word “Gulf” can pull results for the entire Gulf Coast, so a data layer should be checked against both the full county name and 12045. Port St. Joe and Wewahitchka are the county’s two incorporated cities.

Bay County borders the west, Calhoun the north, Liberty the northeast, and Franklin the east, with the Gulf of Mexico to the south. The eastern line approaches the Apalachicola River and its floodplain. Adjacency there does not imply frequent crossings, because lowlands and channels sharply limit direct roads.

What the Map Shows

Port St. Joe occupies the northeastern shore of St. Joseph Bay and concentrates county government at the meeting of U.S. 98 and SR 71. Westbound U.S. 98 passes Highland View, St. Joe Beach, and Beacon Hill before Mexico Beach. The final community is in Bay County, so the boundary near Beacon Hill is essential when sorting otherwise continuous beach labels.

Southeast of the city, U.S. 98 and CR 30A lead toward the Indian Pass and Cape San Blas branches. CR 30E then runs north along the narrow St. Joseph Peninsula to T.H. Stone Memorial State Park. Because the landform extends about 20 miles, the 30A junction, southern cape, park entrance, and northern preserve are separate map positions.

Wewahitchka is the northern incorporated city and the junction of SR 71 and SR 22. It orients trips to Dead Lakes and the lower Chipola River. White City and Dalkeith divide the long SR 71 interior into recognizable segments, while Overstreet belongs to the separate CR 386 corridor in the northwest.

Dead Lakes covers roughly 6,700 acres on the Chipola River across portions of Gulf and Calhoun counties. The Gulf County approach leaves SR 71 north of Wewahitchka for Gary Rowell Road and the recreation area. Cypress snags and submerged stumps make a general location image insufficient for boat navigation.

White City is a central SR 71 reference between the incorporated cities, with Dalkeith farther north. These small labels matter in road-closure, emergency, and address descriptions even though they lack municipal limits. An inland destination should be oriented to SR 71 and these communities before U.S. 98 is considered.

County Layout and Location

The county is elongated north to south but divided east to west by bays, rivers, and wetlands. The lower Apalachicola basin shapes the east, while St. Joseph Bay separates Port St. Joe from the peninsula in the south. Two places that face one another across water may require a return to SR 71 or the 30A–30E junction to connect by road.

SR 71 is the only continuous north–south route from Port St. Joe through White City to Wewahitchka and Calhoun County. U.S. 98 handles coastal movement toward Bay and Franklin counties. SR 22 heads west from Wewahitchka, and CR 386 serves Overstreet and the northwest. Each route answers a different regional direction.

No Interstate enters Gulf County. Regional orientation depends on where U.S. 98, SR 71, and SR 22 cross county lines, followed by the precise 30A, 30E, or Indian Pass branch for a coastal destination. Storms, flooding, shifting sand, and construction can affect these roads, so the static linework should be paired with current FDOT and county notices.

Gulf County’s interactive GIS adds parcels, city limits, flood zones, evacuation zones, and evacuation routes to addresses and streets. A countywide image is best for regional relationships; the local GIS is the appropriate next layer when jurisdiction or hazard planning depends on an exact property.

Hurricane Michael severed the peninsula about one mile north of the state-park entrance in 2018, making 90% of the park inaccessible at the time. Rebuilt facilities are now open, but the event demonstrates why a long barrier landform served by one road cannot be assumed to have permanent shoreline or access conditions.

Local Context

St. Joseph Bay Aquatic Preserve encompasses more than 55,000 acres of submerged land and extensive seagrass habitat. DEP notes that no major river supplies direct freshwater inflow. Although the peninsula shelters much of the water and can make it resemble a closed basin on a small image, the southern opening connects it to the Gulf as a marine bay.

T.H. Stone Memorial St. Joseph Peninsula State Park protects Gulf beach, tall dunes, bay-side marsh, and seagrass habitat near the peninsula’s north end. The peninsula extends about 20 miles, the park includes about 10 miles of beach, and a 1,700-acre wilderness preserve occupies the northernmost section. The full CR 30E approach should therefore be traced as a line rather than reduced to one park point.

Dead Lakes and the lower Chipola floodplain form a freshwater landscape of cypress, backwaters, and seasonally changing channels around Wewahitchka. Farther east lie the Apalachicola lowlands. These northern waters differ completely from the saltwater bay and dune coast, making Wewahitchka the proper organizing point for inland destinations.

Gulf County was formed from southern Calhoun County in 1925 with Wewahitchka as its first seat. A 1964 vote moved the seat to Port St. Joe. Government is now centered in the south, but the history and long travel distance help explain why public services still appear at both ends of the county.

Time labels also require attention. County offices in Port St. Joe publish Eastern Time, while the Wetappo facility on SR 22 in Wewahitchka posts Central Time. An appointment within one county can therefore require checking the specific facility’s address and time-zone notation.

Ways to Use This Map

• Build the basic frame: mark Port St. Joe in the south, Wewahitchka in the north, and trace SR 71 between them.
• Separate the coast: distinguish the U.S. 98 beach communities west of Port St. Joe from the 30A–30E route to Cape San Blas and the peninsula.
• Check county crossings: label Bay, Calhoun, Liberty, and Franklin counties and note the numbered road used at each boundary.
• Read the waters correctly: distinguish marine St. Joseph Bay from the freshwater Dead Lakes–Chipola floodplain.
• Verify a property or field destination: use Gulf County GIS layers for addresses, streets, parcels, city limits, commissioner districts, flood zones, evacuation zones, and evacuation routes.

Start with the SR 71 line between Port St. Joe and Wewahitchka, then add the U.S. 98 coast and the 30A–30E peninsula branch. Place Dead Lakes and the Chipola system in the north and the Apalachicola lowlands in the east. Current evacuation, flood, parcel, and road decisions require the county GIS and responsible agency records.

For a study copy, assign different symbols to incorporated cities, unincorporated communities, beach roads, and evacuation routes. Use separate colors for St. Joseph Bay and freshwater lakes, and different line weights for SR 71 and CR 30E. That visual hierarchy keeps coastal destinations distinct from the inland service corridor.

Frequently Asked Questions

Are Cape San Blas and the St. Joseph Peninsula the same place?

No. St. Joseph Peninsula is the roughly 20-mile landform sheltering the west side of St. Joseph Bay; Cape San Blas identifies the southern cape and nearby address area. Follow CR 30A to the cape junction and CR 30E north toward the state park to separate the southern community, peninsula road, and northern preserve.

The park’s Port St. Joe mailing address does not place it downtown. It lies near the far end of CR 30E after several branches from the city. Arrival and evacuation estimates should use the complete 30A–30E route and the park’s official address rather than the postal city alone.

Which route connects Port St. Joe and Wewahitchka?

SR 71 is the direct north–south spine. It leaves Port St. Joe, passes White City and Dalkeith, reaches Wewahitchka, and continues into Calhoun County. U.S. 98 is the coastal axis and CR 386 serves Overstreet, so neither replaces SR 71 as the basic city-to-city route.

There are few simple parallel alternatives if flooding, a crash, or construction interrupts the corridor. Check the relevant SR 71 segment and the destination’s final turn before departure. During an evacuation, follow Gulf County Emergency Management rather than a generic shortest-route calculation.
