Biking on the Cumberland Island National Seashore is quiet, sandy and wild. You can see far more of the island in a day than you ever could on foot, but only if you bring the right bike and respect three things: the sand, the wind and the ferry clock.
I’ve been to Cumberland Island about a dozen times, most of them in February with BRAG’s Winter Ride Lux. Some visits I’ve walked the island with a professional guide. Others I’ve rolled my steel gravel bike onto the ferry in St. Marys and spent the whole day riding. No two trips have been the same, and each one has taught me something about how to ride this island well. Here’s what I’ve learned.
Should You Bike or Walk Cumberland Island?
If it’s your first or even second visit, walk it with a guide. Save the bike for when you know the island and want to explore on your own.
That might sound strange coming from a cycling organization, but it’s what I tell every rider who asks. Cumberland’s story lives in its ruins, its old families and its landscape. A good guide brings all of that to life, and you’ll miss a lot of it if you’re watching the road for the next patch of soft sand.
Once you’ve been a few times, a bike changes everything. You can cover the south end, the marshes, the beach and the long road north in a single day. That’s when the island’s solitude really opens up.
Getting Your Bike to Cumberland Island
There’s no bridge to Cumberland Island. Everyone arrives by passenger ferry from St. Marys, Georgia, so getting your bike there takes a little planning.
Reserve Your Bike Spot on the Ferry
Bike space on the ferry is limited. The National Park Service caps it at 15 bikes per trip, and you reserve your bike’s spot when you book your ferry ticket. If you’re traveling with a group, tell your trip leader early that you’re bringing a bike. I do this every single time so a spot is held for me.
Rent Your Bike in St. Marys, Not on the Island
Don’t count on renting a bike once you land. The park has said bike rentals on the island are not currently available, so sort out your bike on the mainland before you board.
My go-to is Terry at Camden Bicycle Center in St. Marys. He knows exactly what works on Cumberland and will set you up with the right bike. I once rented a Trek mountain bike from him, and it handled the island beautifully.
What Bike Should You Bring to Cumberland Island?
The wider the tire, the better. That’s the most important decision you’ll make for your ride.
- Leave the road bike at home. Skinny tires and deep sand don’t mix, so don’t even bother.
- A gravel bike works well. I ride a steel gravel bike with 52 mm tires, and it handles most of the island.
- If you’re running tubeless, let some air out. Lower pressure gives you more float in soft sand.
- E-bikes can be great, as long as the tires are wide enough. A motor won’t help much if your tires are sinking.
- Fat bikes are the sand champions. Franklin rides a massive fat-tire bike and rolls right through deep sand where the rest of us end up walking.
What Biking on Cumberland Island Is Really Like
The south end is easy riding, the beach depends on the wind, and the farther north you go, the deeper the sand gets.
Sea Camp to Dungeness
We dock at Sea Camp, and the roads around there are hard-packed enough to ride comfortably. Heading south toward the Dungeness ruins and the marshes around that end of the island, everything is rollable. This is the best place to get a feel for your bike before you take on anything sandier.
Crossing the Dunes to the Beach
Getting to the beach means crossing the dunes, and that’s where you’ll walk. I push my bike through the dunes and deep sand every time. It’s a short slog, and it’s worth it.
Riding the Beach: Let the Wind Decide
Once you reach the beach at low tide, the hard-packed sand near the water is easy riding. Riding north is a breeze, literally, with the wind at your back.
Riding south is a different story. The headwind can be strong, and you’ll work for every mile. If you can, plan your route so you face the tougher direction while your legs are fresh.
The Interior Road North to Plum Orchard
I once rode the main dirt road through the island’s interior up to Plum Orchard Mansion. Most of it was fine. But there are stretches of deep sand, and they get deeper the farther north you go. This is where wide tires, or a fat bike like Franklin’s, really earn their keep.
What You’ll See Along the Way
Wild horses, armadillos, the Dungeness ruins, salt marsh and long stretches of empty beach. On a bike, you can take in all of it in a single day.
That’s the real gift of riding here. You cover a lot of ground, and for long stretches it’s just you, the wind and wild, untouched nature. The solitude is the part I remember most from every ride.
You don’t need a bike to find the wildlife, though. Our riders spot horses and armadillos on the guided walking tour too.
Tips for Biking Cumberland Island
Be Back at the Dock on Time
This is the one tip we give every single rider. The ferry won’t wait for you. Miss it and you’ll either be out there all night or paying for an unplanned stay at Greyfield Inn. We haven’t had anyone miss the boat yet. Fingers crossed.
Give the Wildlife Plenty of Space
Admire the wildlife from a distance. The horses are wild, and they aren’t the friendliest. Give them plenty of room and skip the close-up selfie.
Roll With the Conditions
We don’t build our day around the tides. We have a schedule, and we work with whatever the island gives us, whether that’s high tide, rain or a chilly February wind. That’s part of what makes every visit feel different.
Know Where Bikes Are Allowed
The park allows bikes only on the main road, with no trail riding. Bikes also aren’t allowed in the designated wilderness area on the northern part of the island, so watch for the boundary signs.
How We Do Cumberland Island on Winter Ride Lux
Cumberland Island day is one of the highlights of Winter Ride Lux, and we built it around the same advice I’d give anyone. We take the ferry from St. Marys and hire a professional guide for a historic walking tour through Dungeness, out to the dunes and onto the beach. Interactive moments get worked in as time and weather allow.
Riders who already know the island are welcome to bring an adequate bike and explore on their own.
The Bottom Line
Biking Cumberland Island is a sandy, windy, wonderfully quiet adventure, and it’s at its best for riders who already know the island. If it’s your first visit, walk it with a guide. When you come back, bring the widest tires you can find, ride north with the wind, and above all, be back at the dock on time.
