Overview
St. Marys sits at the southeasternmost corner of Georgia, where the St. Marys River meets the Cumberland Sound before emptying into the Atlantic Ocean. With a population of roughly 18,000, it is a small but historically layered city that has existed in various forms since the late 18th century, making it one of the oldest cities in the United States.
For most visitors, St. Marys serves as the only jumping-off point for Cumberland Island National Seashore, a federally protected barrier island accessible exclusively by ferry from the city's downtown waterfront. This role shapes much of the town's tourism economy, but St. Marys has its own identity worth exploring — a walkable historic district, the Kings Bay Naval Submarine Base (one of the largest in the country), a modest but genuine restaurant and café scene, and quiet waterfront parks.
The pace here is distinctly unhurried. Locals are accustomed to visitors passing through, but the town doesn't feel manufactured for tourism. That balance makes St. Marys particularly appealing to travelers who want access to wild, undeveloped coastline without the atmosphere of a resort town.
Before You Go
No visas are required beyond standard US entry requirements. For guidance on entering the United States, visit TravelerPulse's Visas section and the official US Customs and Border Protection website.
Cumberland Island Ferry Reservations
This is the single most important logistical step for most visitors. The National Park Service operates the ferry to Cumberland Island, and reservations are strongly recommended, especially on weekends and during peak season (spring and fall). Spots fill up well in advance. Check the official National Park Service website (nps.gov/cuis) for current schedules, fees, and booking. Walk-on availability is not guaranteed.
What to Pack
- Sturdy walking shoes or hiking boots (Cumberland Island has sandy trails)
- Insect repellent — mosquitoes and biting gnats (no-see-ums) are persistent, especially in warmer months
- Sunscreen and a hat; shade is limited on the island
- Cash for small local businesses; most accept cards but it's wise to carry some
- Water and snacks if spending a full day on the island, as facilities there are minimal
Weather
Summers are hot and humid with temperatures regularly in the 90s°F and high humidity. Afternoon thunderstorms are common June through September. Winters are mild by national standards — daytime highs typically in the 50s–60s°F — but can occasionally bring frost. Fall and spring offer the most comfortable conditions.
Getting There
By Air
The nearest commercial airport with regular service is Jacksonville International Airport (JAX) in Jacksonville, Florida, approximately 35–40 miles south of St. Marys. From there, a rental car is the most practical option, as there is no direct public transit connection between the airport and St. Marys. Savannah/Hilton Head International Airport (SAV) is also an option for travelers arriving from certain routes, though it is significantly farther — roughly 90 miles north.
By Car
St. Marys is reached via Interstate 95 at Exit 3 (the southernmost exit in Georgia). From I-95, follow GA-40 east approximately 10 miles into the historic district and waterfront. The drive from Jacksonville is under an hour; from Savannah, expect roughly 90 minutes under normal traffic conditions.
By Bus
Greyhound does not serve St. Marys directly. The closest Greyhound stops are in Jacksonville or Brunswick, Georgia. From those points, travelers would need a rideshare or rental vehicle. Verify current schedules at greyhound.com.
Getting Around
St. Marys is a small city and the historic downtown and waterfront district are walkable once you have parked. Most visitors arrive by car, and parking in the downtown area is generally easy to find.
There is no local public bus system serving tourists. Rideshare availability (Uber, Lyft) exists but can be inconsistent, particularly late at night or during off-peak hours — verify app availability before relying on it exclusively.
A personal or rental vehicle is strongly recommended if you plan to explore beyond the immediate downtown area, including beach access at St. Marys Point or the outskirts of town. Bicycles can be a practical option for getting around the flat historic district; verify local rental availability on arrival.
Things to See & Do
Cumberland Island National Seashore
The primary draw for most visitors, Cumberland Island is a 36,415-acre barrier island protecting maritime forest, freshwater ponds, salt marshes, and 17 miles of undeveloped Atlantic beach. Wild horses roam freely across the island — descendants of domestic horses left behind decades ago. Historic ruins including the Carnegie-era Dungeness mansion add a compelling cultural layer to the natural environment. Day trips via the NPS ferry are the norm; backcountry camping is available for those who want to stay overnight (permits required; book through nps.gov/cuis).
St. Marys Historic District
The compact downtown has genuine 19th-century architecture worth a slow walk. The Orange Hall Historic House Museum, a Greek Revival structure dating to the 1820s, offers a window into the area's antebellum history — verify current hours and admission locally before visiting. The First Presbyterian Church and the Oak Grove Cemetery are also notable stops for those interested in local history.
Submarine Museum
The St. Marys Submarine Museum near the waterfront is a small community museum dedicated to the submarine service and the history of Kings Bay Naval Submarine Base. It is an unusual and locally meaningful attraction. Verify current hours and admission fees before visiting.
Waterfront Parks and Walking
The St. Marys Waterfront Park along the St. Marys River is a pleasant place to watch boat traffic, see the ferry depart for Cumberland Island, and observe wading birds and dolphin activity in the river. The area is free and accessible.
Kayaking and Paddling
The tidal creeks and coastal waterways around St. Marys offer excellent paddling. Several outfitters in the area provide kayak rentals and guided tours — verify current operators locally or through the Camden County tourism office.
Food & Drink
St. Marys has a modest but solid dining scene centered on fresh local seafood. Shrimp, oysters, and fish caught in Georgia and Florida coastal waters are staples. The downtown area has a handful of waterfront or near-waterfront restaurants and casual spots.
Expect unpretentious, comfort-forward cooking. There are no Michelin-starred establishments here, but quality is generally reliable at the better-regarded local spots. Dining options thin out quickly beyond the historic district, so plan meals before heading out for long days on Cumberland Island (food and drink access on the island is extremely limited).
A small number of cafés offer breakfast and coffee in the morning — useful to know since ferry departures can be early. Verify current business hours locally, as smaller establishments sometimes keep irregular schedules or close seasonally.
Practical Information
Emergency Services
For emergencies in the United States, dial 911.
Medical
Camden Medical Center is the local hospital serving the St. Marys area. For non-emergency care, urgent care clinics are available in the broader Camden County area. Verify locations and hours locally.
Connectivity
Cell service is generally reliable in the city and downtown area. On Cumberland Island, cell coverage is limited to nonexistent in much of the interior and beach areas — plan accordingly and download offline maps before departure.
Money
ATMs are available in the downtown area and at banks and major retailers. Most businesses accept credit and debit cards, but smaller establishments and the ferry ticket process may have specific payment requirements — check ahead.
Tipping
Standard US tipping conventions apply: 15–20% at sit-down restaurants, $1–2 per drink at bars, and at your discretion for other services.
Safety
St. Marys is generally considered a safe, low-key destination. Standard urban precautions apply — secure valuables in your vehicle and be aware of your surroundings, particularly after dark in less-traveled areas.
Natural hazards deserve more attention here than crime. On Cumberland Island, be aware of alligators near freshwater ponds and marshy areas — maintain distance and never feed them. Stinging insects including yellow jackets can be aggressive in late summer. The Atlantic surf on the island can have strong rip currents; swim only in areas where conditions are clearly safe and heed any posted warnings. Heat and humidity in summer can be intense — stay hydrated on outdoor excursions.
