The Yankee Freedom Ferry is the official ferry to Dry Tortugas National Park, departing daily from Key West. This high-speed catamaran takes visitors on a 70-mile journey across the Gulf of Mexico to explore historic Fort Jefferson and the crystal-clear waters of this remote island paradise. The trip includes breakfast, lunch, snorkeling gear, and entrance to the park. Along the way, passengers may spot dolphins, sea turtles, and other marine life. It’s the most convenient and scenic way to experience one of America’s most isolated—and breathtaking—national parks.

The Yankee Freedom Ferry departs from the Key West Ferry Terminal at 100 Grinnell Street. The terminal features a check-in counter, restrooms, and a waiting area right by the waterfront. Passengers are advised to arrive early—boarding starts around 7:00 a.m. Parking is not free, but convenient, shaded parking is available across the street at the City of Key West Parking Garage (300 Grinnell Street) for about $32–$40 per day. Be sure to pay in advance and place your receipt on your dashboard. The terminal is also within walking distance of downtown Key West.

Fort Jefferson is a massive coastal fortress located on Garden Key in Dry Tortugas National Park. Built in the mid-1800s, it’s one of the largest masonry structures in the Americas, made from over 16 million bricks. Originally intended to protect shipping routes, the fort was never completed or fully armed. Today, visitors can walk its towering walls, explore the powder magazines and prison cells, and learn about its Civil War-era history. Surrounded by crystal-clear waters and coral reefs, Fort Jefferson is both a remarkable feat of engineering and a strikingly remote piece of American history.

The Garden Key Lighthouse, perched atop Fort Jefferson, has guided mariners through the remote Dry Tortugas since 1826. The original brick tower was replaced in 1876 with the current iron structure, which still stands today. Though no longer active, the lighthouse remains a striking landmark and a reminder of the island’s maritime past. Visible from much of Garden Key, it offers a picturesque backdrop to the fort and surrounding turquoise waters, capturing the spirit of isolation and resilience that defines Dry Tortugas National Park.

Bush Key is a small, uninhabited island just east of Garden Key in Dry Tortugas National Park. Accessible by foot via a sandbar during certain times of the year, the island is closed seasonally to protect nesting seabirds—especially sooty terns and brown noddies. With its white sand beaches and protected status, Bush Key offers a rare glimpse into a thriving, untouched seabird sanctuary. While visitors can't always set foot on the island, its natural beauty and bird activity are easily admired from nearby Garden Key or along the connecting sand spit.

The moat wall at Fort Jefferson is a scenic walkway and popular snorkeling spot offering stunning views of the surrounding turquoise waters. However, due to structural damage from recent hurricanes, the moat wall is currently closed for repairs and expected to remain closed through fall 2026. When open, visitors should exercise caution—there are no railings, and the surface can be uneven and slippery. Wear sturdy shoes, supervise children closely, and avoid walking during wet or windy conditions to stay safe while enjoying this unique historic feature.

North Swim Beach is a small sandy shoreline on Garden Key in Dry Tortugas National Park, just steps from Fort Jefferson. It’s a popular spot for swimming, snorkeling, and relaxing in calm, clear waters surrounded by coral reefs. The beach offers easy access from the fort and is ideal for families and visitors seeking a peaceful place to enjoy the island’s natural beauty. As with all areas in the park, visitors should respect fragile marine life and follow safety guidelines, including watching for changing tides and currents.

South Swim Beach is a tranquil sandy spot on the southern side of Garden Key, Dry Tortugas National Park. Known for its calm, crystal-clear waters and vibrant coral reefs, it’s perfect for swimming and snorkeling. The beach offers beautiful views of the open sea and is less crowded than the north side, making it a peaceful retreat for visitors. Like all park beaches, guests should respect the fragile ecosystem, stay aware of currents, and follow safety precautions while enjoying the sun and water.
