Quick facts (AAA, September 26, 2026)

  • Alabama regular: about $4.09 a gallon
  • Alabama diesel: about $6.11 a gallon
  • Vs. the U.S.: about 39 cents below the national regular average of $4.49
  • Cheapest area: the Gulf Coast, around $4.04 in Mobile and Daphne-Fairhope-Foley
  • Main routes: I-65 (Huntsville to Mobile), I-10 along the Gulf, and the I-20 / I-59 Birmingham approach
  • Where to stay: Gulf State Park and Meaher State Park

Gas is expensive across the country this fall, but Alabama is one of the cheaper places to fill up. AAA's late-September averages keep putting it among the least expensive states for gasoline.

That makes Alabama a smart fuel stop on the way to the Gulf Coast. Fill the tank, then spend a day or two on the beach or on Mobile Bay so the pump isn't the whole trip.

Alabama Gas and Diesel Prices Right Now

Here is how Alabama compared with the national average on September 26, 2026, according to AAA:

  • Regular gas: $4.0925 a gallon in Alabama vs. $4.4874 nationally
  • Diesel: $6.1145 a gallon in Alabama vs. about $6.48 nationally
  • Weekly ranking: AAA's weekly roundup around September 25 listed Alabama (about $4.08) among the 10 least expensive gas markets

The other states on that top-10 list were Texas, Indiana, Mississippi, Louisiana, South Carolina, Tennessee, Arkansas, Georgia, and Oklahoma.

These are statewide averages, so the price at any one station can run higher or lower. Compare stations the day you fill up with an app like GasBuddy.

Where Fuel Runs Cheapest in Alabama

The Gulf Coast came in a little lower than the rest of the state. On AAA's September 26 board, Mobile and the Daphne-Fairhope-Foley area both averaged about $4.04 for regular.

Huntsville and Florence-Muscle Shoals ran a few cents higher. The coastal I-10 and AL-59 approaches often price a bit lower than the northern I-65 cities on the same day.

The regional numbers tell the same story. In weekly reports from the U.S. Energy Information Administration, the Gulf Coast has had the cheapest regular gas of any major U.S. region through September 2026, and southern Alabama sits right inside it.

Gulf State Park: Beach Camping Off I-10

Gulf State Park sits in Gulf Shores and Orange Beach, a drive down AL-59 from I-10. It pairs beach access with trails, fishing, paddling, and a big campground.

  • 496 improved campsites, including full-hookup RV sites, waterfront sites, ADA-accessible sites, primitive sites, and glamping
  • 11 modern bathhouses, plus paved pads, picnic tables, and grills
  • A newer RV Resort section with 104 full-hookup sites, concrete pads, and clubhouse-style amenities
  • Things to do: the fishing and education pier, Backcountry Trail biking, and Lake Shelby day use

Nearby, the park points visitors to Gulf Shores and Orange Beach shopping and dining, the Five Rivers Delta Resource Center, Weeks Bay Reserve, and the USS Alabama. Details are on the Alabama State Parks Gulf State Park page.

Meaher State Park: Mobile Bay Without the Beach Traffic

Meaher covers 1,327 acres of wetlands on the north end of Mobile Bay. You get a fishing pier, a boat ramp, and boardwalk views into the Mobile-Tensaw Delta.

  • 108 RV campsites with 50-amp electric, water, and sewer
  • Improved tent sites
  • Bay-side cabins

It's an easy overnight or day stop off I-10. It's also a good pick when you'd rather see the delta than squeeze a big rig through beach traffic. Details are on the Alabama State Parks Meaher page.

How to Plan an I-65 and I-10 Alabama Trip

  1. Fuel smart. Compare stations the day you fill up. The coastal cities ran cheaper on AAA's board, but your exit may be different.
  2. Coming south on I-65? Make Meaher your Mobile Bay day and Gulf State Park your beach and trail base.
  3. Running I-10 east or west? Stay near Mobile or Foley and Gulf Shores instead of driving a 40-foot coach into downtown beach streets for every errand.
  4. Plan your town runs. Foley, Daphne, and Mobile cover groceries, pharmacy, and propane.
  5. Book with your rig in mind. Confirm site length, amp service, and pet rules before you reserve at any state or private park.

Pack for a Humid Gulf Week

On muggy Gulf Coast weeks, a clean drinking-water hose and a regular tire-pressure check matter more than another gadget. Get those right and the rest of the trip gets easier.
