This 310-mile Gulf Coast drive runs from Biloxi, Mississippi to Apalachicola, Florida along US-90 and US-98, covering roughly 6.5 hours of pure drive time best spread over two to three days. October delivers the route’s best conditions: water temps still reach the low 80s°F, crowds thin out after Labor Day, and the oyster season hits full stride. If you want a quieter, food-forward coastal drive that doesn’t duplicate the Florida Panhandle’s more-traveled stretches, this is the one.
The route strings together working fishing towns, white-sand barrier islands, and a genuine oyster capital without requiring a single interstate mile. US-90 carries you east out of Mississippi through the live-oak corridors of the Gulf Coast, then US-98 takes over in Alabama and Florida, hugging the water past some of the least-developed shoreline between New Orleans and Tampa.

Who This Route Is For
- Best for couples or solo drivers who want seafood-focused travel with low-key beach time and no theme-park crowds
- Good for passenger vehicles and smaller RVs (under 30 ft); the Dauphin Island Ferry has a vehicle length limit of 30 ft, so larger rigs must detour via I-10 and I-65 through Mobile
- Not ideal for families seeking major attractions — this route rewards slow stops and local restaurants over water parks or resort strips
- Strong choice for first-time Gulf Coast drivers who have already done the Florida Panhandle corridor (already covered in our Florida Panhandle guide on US-98) and want to extend westward
Biloxi, Mississippi — Start Here
Fill your tank in Biloxi before leaving; gas stations thin out considerably on the Dauphin Island stretch. US-90 east through Biloxi runs right along the beachfront seawall — it’s four lanes of 45 mph with panoramic Gulf views. The Biloxi Visitors Center on Beach Boulevard is a practical first stop for current road and ferry conditions. For breakfast, walk-ins are welcome at The Fillin’ Station Diner on Division Street, where the shrimp and grits run about $13.
Ocean Springs, Mississippi (20 minutes from Biloxi via US-90)
Cross the Back Bay Bridge on US-90 and you’re in Ocean Springs in under 20 minutes. This town punches well above its size for food and art. The Walter Anderson Museum of Art is worth an hour. For lunch, Government Street Grocery is a genuine local counter-service spot with Gulf shrimp po’boys and daily specials written on a chalkboard. October afternoons here are typically sunny and in the mid-70s°F — ideal for walking the downtown blocks before pushing east.
Pascagoula, Mississippi (25 minutes from Ocean Springs via US-90)
Pascagoula is a working port city, not a postcard stop, but the Scranton Nature Center and the short boardwalk along the Pascagoula River are worth 30 minutes. This is also your last reliable fuel point before the Dauphin Island detour — top off here. Take US-90 east to AL-188 south, which runs 20 miles to the Dauphin Island Ferry terminal at Fort Morgan (about 45 minutes from Pascagoula).
Dauphin Island, Alabama (45 minutes from Pascagoula via AL-188)
The Dauphin Island Ferry (vehicle ferry, runs year-round, ~$18–$22 per car in 2026 — confirm rates at the terminal) crosses Mobile Bay from Fort Morgan in roughly 35 minutes and deposits you on Dauphin Island’s eastern end. The island’s Audubon Bird Sanctuary sees heavy fall migration in October; birders regularly spot warblers, raptors, and shorebirds in numbers. The beaches here are quiet and the water is still warm enough for a swim. There’s one small grocery on the island — buy snacks, because Gulf Shores is 30 minutes east and options are limited between.
Gulf Shores, Alabama (30 minutes from Dauphin Island via AL-193 & AL-59)
Gulf Shores marks the transition from quiet to commercial, but Gulf State Park’s 6,150 acres absorb the crowds well. The park’s 2.5-mile beach section on AL-182 is the best free swimming beach on this segment. For dinner, The Gulf restaurant on AL-59 does whole Gulf flounder and local oysters on the half shell — the raw bar is the reason to stop. October weeknights mean no wait.
Pensacola Beach, Florida (1 hour from Gulf Shores via US-98 & FL-399)
US-98 east from Gulf Shores crosses into Florida at Perdido Key, then FL-399 (Via De Luna Drive) cuts across Santa Rosa Island to Pensacola Beach. The white quartz sand here is genuinely fine and bright even in October afternoon light. Fort Pickens Road inside Gulf Islands National Seashore (National Seashore pass or $25/vehicle day fee) runs 7 miles to the 1834 fort at the island’s western tip — it’s a flat, easy drive with Gulf views on both sides. Re-join US-98 east via the Bob Sikes Bridge toward Fort Walton Beach and Destin, then continue southeast. Fuel up in Destin before the 90-mile push to Apalachicola — gas stations on US-98 east of Panama City Beach become sparse.
Apalachicola, Florida (2 hours 15 minutes from Pensacola Beach via US-98)
US-98 delivers you into Apalachicola across the John Gorrie Memorial Bridge with a view of the Apalachicola River delta. This small city (pop. ~2,300) produces roughly 10% of the U.S. oyster supply, and October is prime harvest season. The Apalachicola Oyster House on Water Street shucks to order — a dozen raw runs about $18. The town’s Victorian commercial district on Market Street is compact and walkable. St. George Island, a 9-mile barrier island accessed via the Bryant Patton Bridge (FL-300, ~10 minutes from downtown), has some of the least-developed state park beach in Florida. Dr. Julian G. Bruce St. George Island State Park charges $6/vehicle and closes at sunset.
October seasonal notes: No major road closures expected on this route in mid-October. However, the Gulf of Mexico’s hurricane season runs through November 30. In 2026, monitor the National Hurricane Center for any late-season storm activity before departure — US-98 and FL-300 flood quickly and close with minimal notice during surge events. The Dauphin Island Ferry suspends service in rough weather; call ahead at (251) 861-3000.
FAQ
How long does it take to drive from Biloxi, MS to Apalachicola, FL?
Pure drive time on US-90 and US-98 is approximately 6 hours 30 minutes for 310 miles, not counting the Dauphin Island Ferry crossing (35 minutes) or stop time. Most drivers complete this comfortably in two days with an overnight in Gulf Shores or Pensacola Beach.
Is the Dauphin Island Ferry running in October 2026?
The ferry operates year-round between Fort Morgan, Alabama and Dauphin Island, but suspends service during high winds and rough sea conditions, which occur more frequently in fall. Call the ferry operator at (251) 861-3000 the morning of your crossing to confirm. If it’s closed, the Mobile Bay detour via I-10 and I-65 adds about 90 minutes.
What is the best place to eat oysters on this Gulf Coast drive?
Apalachicola is the destination answer — the Apalachicola Oyster House and Boss Oyster on Water Street both source directly from local aquaculture beds. In Gulf Shores, The Gulf restaurant on AL-59 also serves quality raw Gulf oysters. October is the start of peak oyster season across the northern Gulf.
Are there any road closures or hazards on US-98 in fall?
US-98 has no scheduled fall closures as of October 2026, but hurricane-related flooding remains possible through late November. Sections between Apalachicola and Carrabelle flood during surge events and close with little notice. Check the Florida 511 system (fl511.com) before driving that eastern segment.
Do you need a reservation for Gulf Islands National Seashore in October?
No advance reservation is required to drive or visit Gulf Islands National Seashore in October — timed-entry permits are not in place for fall. The Fort Pickens area charges $25 per vehicle for a 7-day pass. Camping reservations at Fort Pickens Campground should be made in advance via Recreation.gov, as fall weekends fill up.
Is US-98 a good road for RVs?
US-98 handles standard RVs well — it’s a paved, two-to-four-lane highway with wide shoulders through most of its Gulf Coast run. The main constraint is the Dauphin Island Ferry, which limits vehicles to 30 feet. RVs over 30 ft must route through Mobile via I-10 and I-65 rather than taking the ferry, adding distance but no significant difficulty.
