Driving From Atlanta to St. Simons Island

For most people in Atlanta, driving is the simplest and most cost-effective way to get to St. Simons Island.

Typical Driving Route

From central Atlanta (near Downtown or Midtown):

1. Get on I-75/85 South
   • From Midtown, you’ll usually access via I-75/85 near Freedom Parkway, 10th Street, or North Avenue.
2. Follow I-75 South toward Macon
3. Near Macon, take I-16 East toward Savannah
4. Near Savannah, merge onto I-95 South
5. Take the exit toward Brunswick / St. Simons Island (usually GA-25 Spur)
6. Follow signs onto the F.J. Torras Causeway to St. Simons Island

From Hartsfield-Jackson Atlanta International Airport (ATL), you can get directly on I-75 South and follow the same route.

Realistic Drive Times From Different Parts of Atlanta

Times assume normal traffic and minimal stops:

• Downtown / Midtown Atlanta: ~4.75–5.25 hours
• Buckhead / Lenox area: ~5–5.5 hours
• Sandy Springs / Perimeter (I-285): ~5–5.5 hours
• South Atlanta / Hartsfield-Jackson area: ~4.5–5 hours

💡 Tip: Atlanta rush-hour traffic (especially on I-75/85 and I-285) can easily add 30–60 minutes if you leave between about 7–9 a.m. or 4–7 p.m. on weekdays. Many Atlanta drivers prefer to leave:

• Very early morning (before 7 a.m.), or
• Late morning to midday to avoid the worst congestion.

Where You’ll Actually Be Driving

• Atlanta to Macon: Mostly I-75 South, busy near Atlanta but usually smoother after McDonough.
• Macon to Savannah area: You’ll switch to I-16 East. This section is usually less congested but fairly long and rural.
• Savannah area to Brunswick: On I-95 South, more coastal traffic and a bit more truck traffic.
• Brunswick to St. Simons: Short local stretch with the scenic causeway into the island.

Because the route is mostly interstates, it’s generally considered straightforward for Atlanta drivers used to long I-75 or I-85 runs.

Is St. Simons Island a Day Trip From Atlanta?

It’s technically possible to do St. Simons Island as a very long day trip from Atlanta, but most people find it more realistic as a weekend or long-weekend trip.

• Same-day round trip driving:
  • Around 9–11 hours total driving
  • Leaves little time on the island itself
• More realistic:
  • Drive down on Friday or early Saturday, stay 1–2 nights, drive back.

Many Atlanta residents treat St. Simons as a beach weekend or a long holiday weekend destination rather than a quick day-stop.

Flying From Atlanta to St. Simons Island

If you prefer not to drive, there are two main flight-based options from Atlanta:

1. Flying From Atlanta (ATL) to Brunswick (BQK)

The closest airport to St. Simons Island is:

Brunswick Golden Isles Airport (BQK)
295 Aviation Parkway
Brunswick, GA 31525

Key points:

• It’s roughly 15–25 minutes by car from the airport to St. Simons Island.
• From Hartsfield-Jackson Atlanta International Airport (ATL), there are usually limited direct flights to BQK on regional carriers.
• Even with a short flight (around 1 hour in the air), you must factor:
  • Check-in and security time at ATL
  • Possible rental car pickup, taxi, or rideshare from BQK to St. Simons

Door-to-door from Atlanta city to St. Simons lodging, flying can still take 3–4 hours total, sometimes comparable to driving once you add airport time.

2. Flying From Atlanta to Jacksonville, Florida (JAX)

A second option is:

Jacksonville International Airport (JAX)
2400 Yankee Clipper Drive
Jacksonville, FL 32218

• Direct flights from ATL to JAX are typically more frequent than to BQK.
• The drive from JAX to St. Simons Island is around 75–90 minutes.
• This can make sense if:
  • Flight times or prices are better to JAX
  • You’re combining St. Simons with other Florida or coastal stops

However, for most Atlanta travelers, driving the entire way or flying directly to BQK are the more straightforward solutions.

Bus, Shuttle, and Other Ground Options From Atlanta

There is no single, direct public transit line from Atlanta to St. Simons Island, but there are a few partial options:

Intercity Buses (Atlanta → Brunswick)

Some intercity bus services run between:

• Atlanta (usually from downtown or near the Civic Center area)
• Brunswick or nearby coastal stops

If you go this route:

1. Take a bus from Atlanta to Brunswick
2. From Brunswick, use:
   • Taxi,
   • Rideshare (if available), or
   • Local car rental
     to cross the causeway to St. Simons

Total travel time can easily reach 7+ hours, including transfers, and schedules may not line up perfectly for same-day round trips.

Rideshare and Taxis

• Long-distance rideshare from Atlanta directly to St. Simons Island is technically possible, but usually expensive.
• Some Atlanta-based visitors use rideshare only for airport connections, then rely on a rental car or local transport near St. Simons.

In practice, for most people in Atlanta without a car, flying and then renting a car near the coast is more predictable than piecing together buses and ride services.

Best Time of Day to Leave Atlanta for St. Simons

Because you’re crossing the entire state, timing your departure from Atlanta makes a big difference in how long the trip feels.

Leaving Atlanta

• Avoid:
  • Weekday morning rush (7–9 a.m.) heading south on I-75
  • Weekday evening rush (4–7 p.m.), especially if you’re crossing I-285
• Consider:
  • Leaving before sunrise to arrive on St. Simons before lunch
  • Leaving late morning after rush hour for a more relaxed drive

Returning to Atlanta

On the way back from St. Simons:

• If you arrive back around Atlanta’s evening rush, budget extra time on:
  • I-75 North
  • I-285, if you’re heading to Perimeter, Sandy Springs, or the northern suburbs
• Many weekend travelers plan to be within an hour of Atlanta by early afternoon to avoid getting stuck in stop-and-go traffic when they’re already tired from the trip.

What Atlanta Travelers Typically Want to Know

Here are a few practical questions that come up often in Atlanta when planning a St. Simons Island trip.

• With plenty of places to stop for food and restrooms along:
  • I-75 (McDonough, Forsyth, Macon)

  • I-95 (Savannah/Pooler, Richmond Hill, and south toward Brunswick)

Many families break the trip into two longer stops or three shorter stops, especially with small children.

Can I Combine St. Simons With Other Gulf or Atlantic Spots?

If you’re already making the drive from Atlanta, some people add an extra night to explore more than one island, since each is within a short drive once you reach the coast.
