Most folks looking at a map of Northeast Florida assume the trip between Amelia Island and St. Augustine is a straightforward, one-hour shot. Technically? You aren't wrong. If you hop on I-95 and hammer down the gas, you can cover the roughly 68 miles from Fernandina Beach to the nation’s oldest city in about 1 hour and 20 minutes.
But honestly, if that’s all you do, you’re missing the point of the First Coast entirely.
The question of how far is Amelia Island from St Augustine isn't just about odometer readings. It’s about two very different versions of Florida. One is a Victorian-era seaport with a pirate problem (the fun kind), and the other is a Spanish colonial stronghold with cobblestone streets that feel like they belong in Europe.
Distance is relative. Depending on how much you want to see, that 70-mile gap can take ninety minutes or an entire weekend.
The Reality of the Drive: Speed vs. Scenery
When you’re trying to figure out how far is Amelia Island from St Augustine, you basically have two choices. You can take the "efficient" route or the "soul-restoring" route.
The I-95 Sprint (The 80-Minute Dash)
If you’re in a hurry—maybe you have a dinner reservation at Columbia Restaurant in St. Augustine or a tee time—you’ll head west toward Yulee and jump on I-95 South.
The road distance this way is roughly 67 to 70 miles. It’s mostly pine trees and billboards. You’ll bypass the heart of Jacksonville, which is a blessing because Jax traffic can be a nightmare during rush hour. Stay on I-95 until you hit State Road 16 or 207, and you’re in the heart of the historic district.

The A1A Scenic Route (The All-Day Adventure)
Now, if you want the real Florida experience, you take Highway A1A.
This is the route I always recommend to friends. It’s about 72 to 75 miles total, but it feels like a different world. You aren't just driving; you're hopping islands. You’ll pass through Big Talbot and Little Talbot Island State Parks. These spots are famous for Boneyard Beach, where massive, bleached oak skeletons line the shore.
The kicker? You have to cross the St. Johns River.
The St. Johns River Ferry: The Secret Shortcut
Most GPS apps will try to route you around the river via the Dames Point Bridge. Don't listen to them. Instead, take the St. Johns River Ferry (also known as the Mayport Ferry).
It’s a car ferry that connects Fort George Island to Mayport. It runs every half hour.

- Cost: Usually around $7 for a standard car.
- Duration: The actual sail is only about 5 minutes, but the vibes are 10/10.
- Why do it? You get out of the car, feel the sea breeze, and maybe spot a dolphin. It turns a boring drive into a mini-cruise.
Once you’re off the ferry in Mayport, you’re just a straight shot down A1A through Atlantic Beach, Neptune Beach, and Ponte Vedra. This is where the "distance" starts to feel longer because you’ll want to stop every ten minutes for a photo or a taco.
How Far Is Amelia Island From St Augustine by Water?
For the boaters out there, the distance is a bit different. If you’re navigating the Intracoastal Waterway (ICW), you’re looking at about 50 to 60 nautical miles.
I’ve talked to sailors who’ve done this run in a day. It’s a beautiful stretch of the ICW, winding through the Tolomato River. Just keep a sharp eye on the markers. The shoaling near the Matanzas Inlet and the St. Augustine Inlet can be tricky if you aren't paying attention to the tides.
If you're on a slow trawler, expect a 6 to 8-hour journey. In a go-fast center console? You can do it in two hours if the "no-wake" zones don't kill your spirit.
Major Stops Between the Two
If you decide to take the scenic route, these are the spots that actually make the trip worth the extra time:
- Big Talbot Island State Park: Seriously, go to Boneyard Beach. It’s eerie and beautiful.
- The Ribault Club: A bit of 1920s glamour tucked away on Fort George Island.
- Mayport Village: Grab some "Mayport Shrimp" at Singleton’s Seafood Shack. It’s a dive, and that’s why it’s good.
- TPC Sawgrass: Even if you don't golf, the clubhouse in Ponte Vedra is massive and open to the public.
- Guana Tolomato Matanzas Reserve: 73,000 acres of untouched Florida. Great for a quick hike to stretch your legs.
Why Does the Distance Matter?
People often ask about the distance because they want to know if they can do a day trip.
The answer is a hard yes.
If you leave Fernandina Beach at 9:00 AM, you’ll be walking the Castillo de San Marcos by 10:30 AM. You can have a full day of history, grab a datil pepper-heavy lunch, and still be back on Amelia Island in time for a sunset cocktail at the Palace Saloon.
Actionable Tips for Your Trip
- Avoid Rush Hour: Jacksonville traffic is no joke. If you’re heading south between 7:30 AM and 9:00 AM, or north between 4:30 PM and 6:00 PM, stay away from the I-295 beltway.
- Check the Ferry Schedule: The St. Johns River Ferry is reliable, but it does go down for maintenance occasionally. Check the JTA website before you commit.
- Sunscreen is Non-Negotiable: Even in the car, that Florida sun hitting your left arm through the window will cook you.
- Tolls: If you end up on the First Coast Expressway or certain parts of the beltway, you’ll want a SunPass. Most of the A1A route is toll-free (except the ferry).
If you want to make the most of the trip, start your morning on the north end of Amelia Island at Fort Clinch. Walk the ramparts there, then drive south. By the time you reach the Castillo in St. Augustine, you’ll have seen the two most important coastal fortifications in the state.
Map out your route on A1A for the drive down to see the beaches, and take I-95 on the way back when you're tired and just want to get home.
Next Step: You should check the current weather and tide charts for the St. Johns River Ferry to ensure there are no delays for your planned travel date.
