St. Marys Travel Guide

St. Marys sits at the southeastern tip of Georgia on the banks of the St. Marys River, just across from the Florida state line. With a population of under 18,000, it is one of the oldest cities in the United States, with documented settlement dating to the late 18th century. Its streets retain much of that colonial-era character, lined with live oaks draped in Spanish moss and well-preserved 19th-century architecture.

The city is best known today as the primary embarkation point for the ferry to Cumberland Island National Seashore, one of the most pristine barrier islands on the East Coast. Beyond the ferry dock, visitors find a compact and walkable historic district, a working waterfront, and easy access to the marshes and tidal creeks that define coastal Georgia's ecology.

St. Marys is not a resort town. It has a quiet, unhurried atmosphere that suits travelers looking for nature, history, and authenticity rather than theme-park amenities. The presence of Kings Bay Naval Submarine Base gives the local economy a steady, practical character distinct from purely tourist-oriented coastal towns.

Ferry reservations for Cumberland Island

This is the single most important pre-trip task. The National Park Service operates a passenger ferry from the St. Marys waterfront to Cumberland Island. Reservations fill quickly, especially on weekends and during spring and fall. Book well in advance through the official National Park Service reservation system. Verify current schedules, fees, and availability directly with the NPS or at the St. Marys visitor center, as these change seasonally.

What to pack

• Insect repellent is essential, particularly if you plan to visit Cumberland Island or spend time in the marshes. Biting insects can be intense in warmer months.
• Sunscreen and a hat are advisable year-round given the coastal sun intensity.
• Comfortable walking or hiking shoes; trails on Cumberland Island are largely unpaved.
• If visiting in summer (June–August), expect high heat and humidity and plan outdoor activities for early morning.

St. Marys is not served by a commercial airport. The most convenient major airports are Jacksonville International Airport (JAX) in Florida, roughly 40 miles south, and Brunswick Golden Isles Airport (BQK) in Georgia, approximately 35 miles north. JAX offers significantly more airline connections and is the practical choice for most travelers. Verify current rental car availability and ground transportation options at each airport before booking.

By car, St. Marys is accessible via Interstate 95; take Exit 3 and follow Georgia State Road 40 east into town. The drive from Jacksonville takes approximately 45–50 minutes depending on traffic. From Savannah, the drive is roughly two hours via I-95 south.

There is no passenger rail or intercity bus service directly to St. Marys. Travelers without a car will need to arrange a rental or rideshare from Jacksonville or Brunswick.

A personal vehicle is strongly recommended for getting to St. Marys and for flexibility once there, though the historic downtown itself is compact and walkable. Most attractions in town — the waterfront, the museum, the historic churches, and the main dining options — are within easy walking distance of each other.

Rideshare availability (Uber, Lyft) in St. Marys is limited compared to larger cities. Do not rely on it as your sole transportation option, particularly for airport transfers. Verify availability before your trip.

The ferry to Cumberland Island departs from the downtown waterfront. No private vehicles are permitted on Cumberland Island, so all exploration there is on foot or by bicycle. A limited number of bikes can be rented on the island; verify current availability with the NPS.

Cumberland Island National Seashore

The primary draw for most visitors, Cumberland Island is one of Georgia's barrier islands and is federally protected as a national seashore. It features undeveloped Atlantic beaches, maritime forest, ruins of the Carnegie family's Dungeness mansion, and a free-roaming population of feral horses. Hiking trails traverse the island's length. Day trips via the NPS ferry are the standard visit; a small number of backcountry and developed campsites are available for those wishing to stay overnight. Reserve all ferry passages and campsites in advance through the NPS.

St. Marys Historic District

The downtown historic district is listed on the National Register of Historic Places. Notable stops include the orange-painted Orange Hall, a Greek Revival house museum dating to the 1820s; the First Presbyterian Church, one of the oldest continuously operating congregations in Georgia; and the waterfront park along the St. Marys River. Self-guided walking tour maps are typically available at the visitor center.

St. Marys Submarine Museum

Located near the waterfront, this museum tells the story of the submarine service and the significance of Kings Bay Naval Base. It houses artifacts, exhibits, and a periscope visitors can use to view the river. Verify current hours and admission fees locally or on the museum's official site before visiting.

Kayaking and fishing

The tidal creeks, marshes, and rivers surrounding St. Marys offer good opportunities for kayaking and fishing. Several local outfitters offer rentals and guided tours; verify current operators and availability locally.

St. Marys has a modest but genuine local dining scene concentrated in and around the historic downtown. Seafood is the dominant local cuisine — shrimp, blue crab, and fish caught in local waters frequently appear on menus. The town's size means options are limited; visitors with dietary restrictions or very specific preferences should plan accordingly.

Several waterfront and near-waterfront restaurants cater to the ferry crowd and locals alike. Casual, counter-service, and sit-down options exist, but fine dining in the traditional sense is not a primary feature of the town. A handful of bars and casual spots serve craft beer and cocktails.

Grocery and convenience options are available in town for self-catering. If you are camping on Cumberland Island, all food and supplies must be brought from the mainland — there are no food services on the island. Plan and pack accordingly.

Emergency contacts

For any emergency in the United States, dial 911. For non-emergency local matters, contact the Camden County Sheriff's Office or St. Marys Police Department — verify current non-emergency numbers locally.

Visitor information

The St. Marys Convention and Visitors Bureau maintains a visitor center near the waterfront. Staff can provide current maps, ferry information, and local recommendations. Hours vary; verify before relying on it for time-sensitive needs.

Connectivity

Cell coverage in the downtown area is generally adequate with major US carriers. Coverage on Cumberland Island is limited to nonexistent in many areas — download offline maps before departing the mainland.

Weather considerations

Summers are hot and humid with afternoon thunderstorms common. Hurricane season runs June through November; monitor forecasts if visiting during this period. Spring and fall offer the most comfortable conditions. Winters are mild by national standards but can bring occasional cold snaps.

St. Marys is a small coastal community and is generally considered safe for visitors. Standard travel precautions apply: be aware of your surroundings, secure valuables in your vehicle, and avoid leaving items visible in parked cars.

Outdoor safety is a more meaningful concern here than urban safety. On Cumberland Island and in the surrounding marshes, be alert for alligators — they are present and should be given wide berth. Do not feed them. Eastern diamondback rattlesnakes and other venomous snakes inhabit the island and surrounding areas; watch where you step, particularly in tall grass and near fallen logs.

Ocean swimming at Cumberland Island's beaches carries typical Atlantic coast risks including rip currents. There are no lifeguards on Cumberland Island beaches. Swim with caution and heed posted advisories.
