How to Explore Cumberland Island Ferry from Jax

Cumberland Island, a remote and pristine barrier island off the coast of Georgia, is one of the most untouched natural treasures in the southeastern United States. Accessible only by ferry, the island offers visitors a rare opportunity to experience wild beaches, ancient forests, historic ruins, and abundant wildlife—all without the crowds of typical tourist destinations. For travelers based in Jacksonville, Florida (Jax), the journey to Cumberland Island is not only feasible but deeply rewarding. Understanding how to navigate the ferry system from Jax requires careful planning, local knowledge, and an appreciation for the island’s protected status. This comprehensive guide walks you through every essential step to ensure a seamless, memorable, and sustainable visit to Cumberland Island via the ferry service originating near Jacksonville.

Unlike conventional vacation spots, Cumberland Island National Seashore is managed by the National Park Service (NPS) with strict regulations designed to preserve its ecological integrity. This means that access is limited, reservations are mandatory, and transportation options are few. The primary gateway for visitors from Jax is the St. Marys, Georgia ferry terminal, located approximately 45 minutes south of downtown Jacksonville. While the island itself is part of Georgia, its proximity to Florida makes it an ideal weekend escape for residents of the First Coast. This guide demystifies the process, offering actionable steps, insider tips, and practical tools to help you plan your trip with confidence.

Whether you’re a nature photographer seeking untouched dunes, a history enthusiast drawn to the ruins of the Carnegie estate, or a hiker craving solitude along miles of undeveloped shoreline, Cumberland Island delivers an experience unlike any other. But without proper preparation, even the most enthusiastic traveler can encounter delays, missed departures, or disappointed expectations. This tutorial is designed to eliminate guesswork. By the end, you’ll know exactly how to book your ferry, what to pack, how to navigate the island, and how to minimize your environmental impact—all while maximizing your time on one of America’s most extraordinary coastal landscapes.

Step-by-Step Guide

Step 1: Confirm Your Travel Dates and Island Availability

Before making any bookings, verify that Cumberland Island National Seashore is open for public access on your desired dates. The island is closed during specific periods, including federal holidays, severe weather events, and occasional maintenance windows. The National Park Service updates its calendar monthly on its official website, so check nps.gov/cuis before finalizing your plans. Peak season runs from late March through early November, with the highest demand occurring between May and September. During these months, ferry slots fill quickly—sometimes weeks in advance.

Additionally, confirm that the ferry service is operating. The Cumberland Island Ferry is operated by a private concessionaire under contract with the NPS. While the service is reliable, cancellations can occur due to high winds, rough seas, or mechanical issues. Always review the weather forecast for the St. Marys area 48 hours before departure. If conditions are unfavorable, the ferry may be delayed or canceled with little notice. Have a backup date in mind.

Step 2: Book Your Ferry Ticket in Advance

Ferry tickets are not available at the terminal on the day of departure. All reservations must be made online through the official booking portal: cumberlandislandferry.com. This site is the only authorized platform for purchasing tickets. Third-party resellers are not affiliated with the NPS and may charge inflated prices or sell invalid tickets.

When booking, you’ll select your departure date, round-trip or one-way option, and passenger count. There are two daily departures from St. Marys: a morning departure at 8:00 a.m. and an afternoon departure at 1:00 p.m. The morning ferry is strongly recommended for first-time visitors, as it provides the most daylight hours to explore the island. The afternoon ferry is better suited for day-trippers who want to limit their time on the island to four to five hours.

Ticket prices vary by season and passenger type. As of the latest update, adult round-trip fares range from $42 to $58, with discounts available for seniors (62+), military personnel, and children (ages 3–11). Infants under 2 ride free. Payment is processed securely via credit card only. You will receive a digital confirmation via email—print it or save it on your mobile device. No physical tickets are issued.

Step 3: Plan Your Drive to the St. Marys Ferry Terminal

The ferry terminal is located at 1001 Ferry Landing Road, St. Marys, Georgia, 31558. From downtown Jacksonville, take I-95 South for approximately 42 miles. Exit at Georgia State Route 40 (exit 40), then follow signs to St. Marys. The drive takes about 45 minutes under normal conditions, but allow extra time during rush hour or if weather is poor.

Once you arrive in St. Marys, follow signs for the “Cumberland Island Ferry.” The terminal is located at the end of a long, paved road with ample parking. Parking is free and includes designated spaces for RVs and trailers. Arrive at least 90 minutes before your scheduled departure. This allows time to check in, use restrooms, purchase last-minute supplies, and board without rushing.

Do not attempt to arrive less than 60 minutes before departure. The check-in process includes verifying your reservation, collecting boarding passes, and receiving a safety briefing. Late arrivals are not permitted to board. The ferry departs promptly at the scheduled time, and no exceptions are made.

Step 4: Prepare for the Ferry Ride

The ferry ride to Cumberland Island lasts approximately 45 minutes. The vessel is a modern, climate-controlled catamaran with indoor and outdoor seating. Restrooms are available on board. Bring water, snacks, and a light jacket—the wind off the Atlantic can be brisk, even on warm days. There are no concessions on the ferry, so plan accordingly.

Passengers are not permitted to bring alcohol, glass containers, or large coolers. Small, soft-sided coolers (under 12 quarts) containing non-alcoholic beverages and snacks are allowed. Pets are strictly prohibited on the ferry and the island, with the exception of service animals registered in advance with the NPS.

During the crossing, park rangers often provide brief commentary on the island’s ecology, history, and wildlife. Listen closely—this is your first introduction to the unique environment you’re about to explore. Keep your eyes open for dolphins, ospreys, and the occasional sea turtle near the ferry’s wake.

Step 5: Navigate the Island Upon Arrival

Upon docking at the main pier on Cumberland Island, you’ll be greeted by a park ranger who will distribute maps and answer any immediate questions. The island spans 36,000 acres, and there are no paved roads or public transportation. All exploration is done on foot, by bicycle, or via private vehicle (if you’ve arranged a shuttle in advance).

For most visitors, walking is the best way to experience the island. The main trailhead is a short walk from the pier. The Dungeness Ruins, the most popular destination, is a 2.5-mile round-trip walk along a shaded, sandy path. Other notable sites include the Plum Orchard Mansion, the Sea Island Cotton Farm ruins, and the remote beaches of the northern end of the island.

Bring a physical map (downloadable from nps.gov/cuis) or a GPS-enabled device with offline maps. Cell service is nonexistent on the island. Water is not available at most trailheads, so carry at least one liter per person per hour of hiking. The island’s climate is humid and hot in summer, so plan your hikes for early morning or late afternoon to avoid peak temperatures.

Step 6: Choose Your Return Ferry Time

Ferry return times are fixed and non-negotiable. The last departure from Cumberland Island is at 4:00 p.m. daily. If you take the morning ferry, you’ll have approximately 7–8 hours on the island. If you take the afternoon ferry, you’ll have only 4–5 hours. Plan your activities accordingly.

There are no facilities on the island for storing luggage or leaving belongings unattended. Pack only what you can carry. If you’re staying overnight (see Step 7), you’ll need to coordinate with the park service to leave your gear at the ranger station or campsite.

Be at the pier at least 45 minutes before your scheduled return. Boarding begins 30 minutes prior to departure. The ferry will not wait for latecomers. Missing your return ferry means you’ll be stranded on the island until the next day’s departure—something that can only be arranged in extreme emergencies and at significant additional cost.

Step 7: Consider Overnight Stays

For those seeking a deeper connection with the island, overnight camping or lodging at the historic Greyfield Inn is available. Camping requires a separate permit from the NPS and can be reserved up to six months in advance. There are four designated campgrounds on the island, each with pit toilets and picnic tables. No electricity, running water, or showers are available. Campfires are prohibited; only portable stoves are allowed.

The Greyfield Inn, a restored 19th-century mansion, offers luxury accommodations for up to 32 guests. Rooms are rustic-chic, meals are included, and guided walks are provided. Reservations open annually on January 1 and fill within hours. If you’re serious about staying overnight, book immediately upon release.

Day-trippers are not permitted to stay past the last ferry. Overnight guests must coordinate their ferry arrival and departure times with their lodging. The ferry schedule is synchronized with both camping and inn reservations.

Best Practices

Minimize Your Environmental Impact

Cumberland Island is a designated National Seashore for a reason. Its ecosystems are fragile and easily disrupted. Follow Leave No Trace principles rigorously: pack out everything you bring in, including food wrappers, biodegradable items, and even fruit peels. Never feed wildlife—wild horses, deer, and alligators are not pets. Keep a safe distance from all animals, especially the island’s famous feral horses. They may appear tame, but they are wild and unpredictable.

Stay on marked trails to prevent erosion and protect native vegetation. Off-trail hiking is permitted only in designated areas and requires a permit. Avoid stepping on dune grasses—they stabilize the shoreline and prevent beach loss. If you’re photographing birds or wildlife, use a zoom lens rather than approaching closer.

Plan for Weather and Climate

The coastal climate of Cumberland Island is humid subtropical. Summers are hot and wet, with afternoon thunderstorms common. Spring and fall offer the most pleasant conditions, with temperatures ranging from 65°F to 80°F. Winter is mild but windy, with temperatures occasionally dipping into the 40s. Always check the forecast for St. Marys, not Jacksonville, as conditions can differ significantly across the water.

Bring sun protection: broad-spectrum sunscreen, a wide-brimmed hat, and UV-blocking sunglasses. Mosquitoes and ticks are prevalent, especially in wooded areas. Use EPA-approved insect repellent containing DEET or picaridin. Tuck pants into socks when hiking through tall grasses to reduce tick exposure.

Bring the Right Gear

Essential items include:

• At least 2 liters of water per person
• High-energy snacks (trail mix, energy bars, dried fruit)
• Sturdy, broken-in hiking shoes or boots (sandals are not recommended)
• Lightweight, breathable clothing in layers
• Waterproof rain jacket or poncho
• Reusable water bottle and collapsible cup
• Binoculars for wildlife viewing
• Camera with extra batteries
• First-aid kit with blister treatment
• Headlamp or flashlight with extra batteries
• Portable power bank for your phone

Do not bring:

• Alcohol
• Glass containers
• Large coolers or ice chests
• Fireworks or open flames
• Drone devices
• Non-service animals

Respect Cultural and Historical Sites

The island contains numerous historic structures, including the Carnegie family’s summer home, the ruins of Dungeness, and remnants of 19th-century cotton plantations. These sites are protected under federal law. Do not touch, climb on, or remove any artifacts. Even small items like buttons, bricks, or shell fragments are part of the island’s archaeological record. Take only photographs and leave only footprints.

Interpretive signs are placed at key locations. Read them to understand the context of what you’re seeing. Rangers are available for guided walks—sign up early, as space is limited.

Travel with a Group or Buddy System

While solo travel is permitted, the island’s isolation and lack of communication infrastructure make it safer to travel with at least one other person. Inform someone outside your group of your itinerary and expected return time. If you become lost or injured, having a companion increases your chances of safety and rescue.

Always carry a whistle. In an emergency, three blasts are the universal distress signal. If you’re hiking far from the main trails, carry a personal locator beacon (PLB) or satellite messenger. Cell phones are useless here.

Real Examples

Example 1: The Photography Trip

Emily, a professional photographer from Jacksonville, planned a two-day trip to Cumberland Island to capture the island’s wild horses and sunrise over the Atlantic. She booked her ferry tickets three months in advance and reserved a spot on the 8:00 a.m. departure. She packed a lightweight tripod, two camera bodies, extra batteries, and a drone (which she did not fly, per NPS regulations). She hiked to the Dungeness Ruins by 9:30 a.m., where the morning light illuminated the crumbling brick arches. By noon, she was on the northern beach, photographing a pod of dolphins feeding near the shore. She returned on the 4:00 p.m. ferry with over 500 high-quality images. Her success came from meticulous planning and respecting the island’s rules.

Example 2: The Family Day Trip

The Martinez family from Jacksonville—parents and two children ages 7 and 10—visited Cumberland Island for the first time. They booked the 8:00 a.m. ferry and packed light: water, granola bars, sunscreen, and a small first-aid kit. They rented a tandem bicycle at the pier (available for $15/half-day) and rode the 1.5-mile loop to the Dungeness Ruins. The kids loved spotting crabs and learning about the island’s history from the ranger-led talk. They returned on the 4:00 p.m. ferry, exhausted but exhilarated. They later said it was the most memorable family outing they’d ever had.

Example 3: The Solo Hiker

James, a retired teacher from Jacksonville, hiked the 12-mile round-trip to the northern beaches of Cumberland Island. He left at 8:30 a.m., carried 3 liters of water, and brought a PLB device. He camped overnight at the Sea Island campground and woke to the sound of waves and distant horse calls. He hiked back to the pier by 2:30 p.m. and boarded the 4:00 p.m. ferry. He documented his journey in a journal and later wrote a blog post that helped others understand the solitude and beauty of the island. His trip was successful because he prepared for solitude and knew his limits.

Example 4: The Missed Ferry

A group of four friends from Jacksonville arrived at the ferry terminal at 1:45 p.m. for a 2:00 p.m. departure. They had not booked tickets online and assumed they could buy them on-site. They were turned away. The next available ferry was three days later. They spent the afternoon in St. Marys, visiting the local museum and seafood market—unplanned, but still enjoyable. Their lesson: never assume availability. Book early, always.
