Cumberland Island & the Wild Horses

Georgia’s largest barrier island is reachable only by ferry from St. Marys — about a 45-minute drive from Jacksonville plus a scenic 45-minute crossing. The payoff: free-roaming wild horses, undeveloped beaches, and Gilded-Age ruins.

Getting there

Cumberland Island sits just over the Georgia line, and the whole adventure starts with an easy drive. From most of Jacksonville it’s about 45 minutes north to the little waterfront town of St. Marys, Georgia, where the National Park Service runs its mainland visitor center. Park, check in, and you’re ready for the only way onto the island that isn’t a private boat: the ferry.

The ferry crossing takes about 45 minutes and is part of the fun — you’re gliding through tidal salt marsh and open sound with a good chance of spotting dolphins before you ever set foot on sand. Boats land at two stops on the island’s sheltered western side: Sea Camp (the main dock, near the campground and the start of most trails) and Dungeness (closest to the famous ruins and the most reliable horse-watching).

Here’s the thing first-timers don’t expect: there are no cars on Cumberland Island. No roads to drive, no shuttles, no Ubers. You explore on foot, and that quiet is exactly what makes the place feel like a different century. If you’d rather cover more ground, bikes can be rented at Sea Camp — a smart move if you want to reach the beach, the ruins, and a stretch of maritime forest all in one day visit.

Planning a string of coastal escapes from the city? This one pairs naturally with our other northbound runs — see the full Day Trips hub for the lineup.

The quick math

~45 min drive to St. Marys + ~45 min ferry across the sound. No cars on the island — go on foot, or rent a bike at Sea Camp to see more in a day.

On the island

What you’ll find

A whole island of it — and almost none of it developed. Here’s what to point yourself toward once you step off the ferry.

THE MAIN EVENT

Free-roaming wild horses

Cumberland’s feral horses wander the dunes, marsh edges, and lawns completely untended — and seeing them loose against the ruins is the image you came for. Your best odds are around the Dungeness historic district, about half a mile from the Dungeness dock. Watch them, photograph them, and keep your distance: these are genuinely wild animals, not a petting zoo.

GILDED AGE

The Dungeness mansion ruins

The skeletal remains of the Carnegie family’s grand Dungeness estate are the island’s most photographed landmark — soaring brick chimneys and arches half-swallowed by greenery, with horses often grazing the grounds. It’s an easy walk from the Dungeness dock and the natural anchor for a first visit.

THE SHORE

Miles of undeveloped beach

Cross the island’s spine and you reach a beach that runs for miles with no condos, no boardwalk, no snack bar — just dune, shell, and surf. It’s about as wild as Atlantic shoreline gets. If empty sand is your thing, you’ll also want our Beaches & Outdoors guide for the closer-to-home stretches.

THE INTERIOR

Maritime forest

Between dock and dune runs a shaded canopy of wind-sculpted live oaks, saw palmetto, and Spanish moss. The forest trails are flat, cool, and quiet — a welcome break from the open sun and a good place to slow down and listen.

FAR NORTH END

The Carnegie-era Plum Orchard mansion

Another grand Carnegie property, the Plum Orchard mansion sits well up the island and is far enough that most day-trippers don’t reach it on foot. If it’s on your list, plan your timing carefully around ferry returns — or save it for an overnight stay so you’re not racing the clock.

Plan the timing
Plan ahead: Cumberland Island is wild on purpose, and a day trip here rewards the people who prep. A few non-negotiables: the ferry sells out, often days or weeks ahead in peak season, so reserve in advance rather than showing up and hoping. There’s also a $15 National Park Service entrance fee on top of the ferry. And because services on the island are limited, pack your own water and food — there’s no grocery run once you’re across the sound. Bring sunscreen, bug spray, and comfortable shoes for walking.

Make it a night

Where to sleep: A day trip is plenty, but Cumberland gets under your skin and some travelers want to stay. The island’s only hotel is the historic Greyfield Inn — an all-inclusive Carnegie-family mansion that’s a destination in its own right (and books up well ahead). If that’s out of reach, base yourself on the mainland in St. Marys, where there’s a range of lodging a short drive from the ferry dock. Either way, you’ll catch the morning boat rested instead of rushing up from Jacksonville at dawn. For ideas closer to the city, our Where to Stay guide has the Jacksonville side covered.

Common questions

How do you get to Cumberland Island from Jacksonville?

It's about a 45-minute drive north to St. Marys, Georgia, where the National Park Service runs the mainland visitor center. From there the only way onto the island (short of a private boat) is the ferry, a scenic crossing of about 45 minutes.

Do you need a reservation for the Cumberland Island ferry?

Yes, reserve in advance. The ferry sells out, often days or weeks ahead in peak season, so book ahead rather than showing up and hoping for a spot.

Where are the best odds of seeing the wild horses on Cumberland Island?

Your best bet is around the Dungeness historic district, about half a mile from the Dungeness dock. The horses roam completely untended, so watch and photograph from a distance since these are genuinely wild animals.

Are there cars on Cumberland Island?

No. There are no cars, roads, shuttles, or Ubers on the island. You explore on foot, or you can rent a bike at Sea Camp to cover more ground in a single day visit.

Is there an entrance fee for Cumberland Island?
