Dry Tortugas National ParkNestled 70 miles west of Key West, Florida in the serene cerulean waters of the Gulf of Mexico lies Dry Tortugas National Park, a cluster of seven pristine islands that appear like mere specks in the vast ocean.

As one of America’s most remote and least visited national parks, Dry Tortugas exudes an aura of mystery and seclusion.

The largest island, Garden Key, holds the star attraction—the 19th century Fort Jefferson, an enormous yet unfinished coastal fortress made from 16 million bricks that today remains remarkably intact.

For overlanders seeking an overlanding escape from the bustle of the mainland, a visit to Dry Tortugas National Park feels like stepping into another world entirely. The national park offers a bounty of historic sights and natural wonders to uncover.

Meander along the empty beaches, dive into the crystal clear waters to discover a dazzling marine ecosystem, wander the fort’s maze-like walls, or simply find a spot to sit back and soak up the laidback island vibes.

This comprehensive overlander guide provides all the information you need to plan your next adventure in this hidden coastal paradise. Come ready to be enchanted by Dry Tortugas National Park!

Getting to Dry Tortugas National Park

Seaplane at Dry Tortugas National ParkDry Tortugas National Park is a remote island located approximately 70-miles (113 km) west of Key West, Florida.

Since the 100-square mile park is only made up of islands, there is no land access by car.

Reaching this isolated park requires careful planning to arrange transportation by boat or seaplane.

Overlanders have four main options to access Dry Tortugas:

  1. Personal Boat: Arriving by private vessel requires obtaining proper permits in advance from the park service for anchoring, mooring, and disembarking on the islands.
  2. Charters & Permitted Guides: Hiring an authorized charter tour operator provides guided fishing, diving, snorkeling and wildlife viewing excursions on powered or sailing vessels. This hassle-free option handles all the details.
  3. Yankee Freedom Ferry The Yankee Freedom III ferry offers high-speed catamaran trips to Garden Key from Key West. Reservations for the Yankee Freedom Ferry can be made through https://www.drytortugas.com/. The ferry service can accommodate day trips or overnight camping adventures in the park.
  4. Key West Seaplane Charters Flying to Dry Tortugas on a seaplane charter provides unique aerial views of the islands, Fort Jefferson monument and extraordinary surrounding seascapes. Reservations for the Key West Seaplane Charters can be made through https://keywestseaplanecharters.com/. Half day, full day and custom tours are available.

With strategic transportation planning, overlanders can gain access to enjoy the breathtaking beauty and fascinating history of remote Dry Tortugas National Park.

Exploring Dry Tortugas National Park

Before you enter the park, however, make sure you’re aware that there is a $15 per person entrance fee to enter the park. If you plan to visit other national parks throughout the year, I suggest you purchase the America the Beautiful annual pass. It’s a much better bargain!

Setting Foot in Paradise

Arriving by sea or air, you’ll step onto the park’s pristine sugar-sand beaches and be surrounded by a crystal blue seascape. Breathe in the tropical air and listen to waves gently lapping the shore, with not a trace of development in sight.

Don your snorkel to float over colorful corals and turtle grass or stroll the beachcombing for seashells and ocean-polished glass. This is nature at its most untouched and serene.

Fort Jefferson: A Historical Marvel

Fort Jefferson at Dry Tortugas National ParkThe park’s centerpiece, Fort Jefferson, is an engineering marvel that seems to rise straight from the sea. As one of the largest 19th century coastal fortifications in America, this brick citadel protected vital shipping channels for decades.

Walk the fort’s maze-like halls, climb narrow stairways to reach the top of its 45-foot walls, and imagine the lives of soldiers who once occupied its quarters. Gaze out at the expansive ocean views that surround this island stronghold lost in time.

Snorkeling and Diving Delights

For snorkelers and divers, the park’s protected reefs are the main draw. Just offshore, nurse sharks dart through spur and groove coral formations as green sea turtles munch on seagrass.

Swim through the ribbon-like Golden Staircase covered in colorful sponges or dive The Moat to explore the fort’s submerged foundations. Currents whisk you over massive brain corals, sea fans, and fields of garden eels. The variety of marine life in this underwater playground is astonishing.

Beach Bliss and Beyond

Snorkeling at Dry Tortugas National ParkPack a picnic lunch to enjoy on the sandy expanse of South Beach, or try beachcombing along East Key’s shoreline where seashells wash up in abundance. Cast a fishing line from the pier beneath Fort Jefferson and reel in snapper for dinner.

Abundant Wildlife

Birdwatchers rejoice! Dry Tortugas is a hotspot for viewing soaring brown pelicans, migratory warblers, and the aerial acrobatics of magnificent frigatebirds.

Join a turtle walk to see loggerheads nesting on the beaches or glimpse shy Cuba anoles scurrying through island foliage. Even underwater, spotted eagle rays and barracudas make frequent appearances. The diversity of island and marine life delights nature enthusiasts.

Exploring Loggerhead Key

Visiting Loggerhead Key provides a quieter, more remote island experience. Follow sandy trails around the edge, snorkel vibrant reefs, or tour the 1857 lighthouse for panoramic views. While inland access is restricted, the island’s shores offer exceptional kayaking, swimming, and nature watching.

With endless natural beauty and fascinating history, Dry Tortugas National Park promises overlanders an unforgettable tropical island adventure.
