Field briefing
Cumberland Island National Seashore starts with access, not mileage.
Before you go
Nearly every visitor arrives on the Cumberland Island Ferry from St. Marys, and both the boat and the island are capacity-limited, so the round-trip ferry reservation is the single thing to book first. Ferry tickets and your $15 entrance fee are separate, the boat runs seven days a week from March through November and only five days (Thursday through Monday) in winter, and the last return leaves in the afternoon, so a missed boat means a missed plan. There are no stores, no food service, and limited water on the island, so carry in everything you need for the day.

Weather, crowds, and what the season changes about the trip.
Warm, breezy days with blooming maritime forest and rising humidity by late May.
Pack Booked ferry slot, sun protection, and bug spray for the marsh edges.
Hot, humid, and buggy, with afternoon thunderstorms and strong sun on the open beach.
Pack Lots of water, sun shirt, insect repellent, and a hat for shadeless beach miles.
Mild and clear once humidity drops, often the most comfortable hiking weather of the year.
Pack Layers for cool mornings, a booked ferry, and shoes for sandy mixed terrain.
Cool and quiet, with chilly mornings, a reduced five-day ferry schedule, and few visitors.
Pack Warm layer, wind shell, and a confirmed ferry day since runs pause midweek.
Dungeness ruins and the wild horses
The burned Carnegie mansion, surrounded by the feral horses Cumberland is famous for, a short walk from the Sea Camp dock.
Sea Camp Beach and the dune crossing
The closest stretch of empty Atlantic beach to the dock, reached on a flat boardwalk through live oaks and palmetto.
Plum Orchard mansion
A grand Carnegie estate deep on the island, reachable by a long bike or hike, or a separate ferry add-on on select days.
Put the access rule first: shuttle, parking, timed-entry, or reservation windows should decide the order of the day. For one day in Cumberland Island National Seashore, make Dungeness ruins and the wild horses the non-negotiable, add Sea Camp Beach and the dune crossing only if the first stop runs clean, and keep Plum Orchard mansion as the flexible finish.

Most visitors base in St. Marys, the small ferry-port town on the mainland, which has inns, motels, and restaurants within walking distance of the dock and the visitor center. The historic Greyfield Inn is the only lodging on the island itself, a private Carnegie estate with its own boat and a premium all-inclusive rate. Campers stay on the island at Sea Camp (developed, near the dock), Stafford Beach (a 3.5 mile walk in), or the primitive backcountry sites farther north.
Camping reservations
Cumberland Island camping is genuinely planned, not spontaneous. You reserve a campsite on Recreation.gov, then reserve a ferry crossing on a day that fits your nights, and you carry in all food and most water. Sites at Sea Camp book out months ahead for good weekends.

Weather windows, boat schedules, flight buffers, and backup days shape what is realistic.
Getting there
Arrival note
The island is reached from St. Marys, Georgia, about an hour from Jacksonville.
Transfer plan
Park in St. Marys, check in at the mainland visitor center to pay your entrance fee, then board the reserved Cumberland Island Ferry for the 45 minute ride to the Sea Camp dock.
Transfer plan
There is no vehicle access and no bridge, and private boats may land but everyone still pays the entrance fee.
Pair this with lodging: the best base is the one that protects the departure window, pickup point, or weather buffer.
You need a ferry reservation. The island has no bridge, so almost everyone arrives on the Cumberland Island Ferry from St. Marys, which is capacity-limited and should be booked first. Day visitors do not need a separate access permit beyond the ferry seat and the $15 entrance fee.
There is a $15 per person entrance fee plus a round-trip ferry ticket, which runs about $44 for adults, $42 for seniors, and $34 for youth. The entrance fee and the ferry are paid separately.
Yes, but it takes two reservations that must match: a campsite on Recreation.gov (Sea Camp, Stafford Beach, or a primitive backcountry site) and a ferry day that lines up with your nights. Sea Camp books out months ahead for good weekends.
Yes. A free-roaming herd of feral horses lives across the island and is often seen around the Dungeness ruins near the south-end dock. They are wild animals, so keep your distance and never feed them.
