Loggerhead Key

The waters around the Dry Tortugas have long been treacherous, studded with reefs and shoals that wrecked many ships, and the tall Loggerhead Key lighthouse was built to warn mariners away. Rising high above the low island, the historic lighthouse has operated for well over a century and remains a striking landmark visible for miles across the sea.

Loggerhead Key itself is a low, sandy island covered in hardy vegetation, home to nesting sea turtles and seabirds, with quiet beaches and clear water lapping its shores. Its remoteness and small size give it a peaceful, end-of-the-world feel, a contrast to the busier Garden Key with its fort.

Loggerhead Key is prized for snorkeling, with healthy reefs offshore and, nearby, the Windjammer wreck, the remains of a sailing ship that sank on the reef, now an artificial reef swarming with fish and easily explored in shallow water. The clear, protected waters make for excellent underwater viewing.

Getting to Loggerhead Key takes extra effort, since the regular ferry serves Garden Key, not Loggerhead. Visitors reach it by private boat or, for the very experienced and prepared, by kayak across open water, so it sees far fewer people. There are no services on the island, so bring everything you need, check conditions carefully, and be prepared for a remote, self-sufficient adventure.

Loggerhead Key is the largest island in Dry Tortugas National Park, Florida, located a few miles west of Fort Jefferson. It is best known for its tall, historic 19th-century lighthouse, which has guided ships past the area's dangerous reefs and shoals for over 150 years. The low, sandy island is covered in hardy vegetation and ringed by clear water and quiet beaches, and it is home to nesting sea turtles and seabirds. Loggerhead Key is prized for its excellent snorkeling, including the nearby Windjammer shipwreck site. Reached only by private boat or kayak rather than the regular ferry, it is far less visited than Garden Key, offering solitude, history, and some of the clearest water in the park to those who make the extra effort to get there.

The Windjammer wreck is the popular name for the remains of a sailing ship, historically the Avanti, that sank on a reef near Loggerhead Key in Dry Tortugas National Park in the early 1900s. Today the ship's iron skeleton lies in relatively shallow water, where it has become an artificial reef, encrusted with coral and swarming with fish. This makes it a favorite snorkeling and diving site, since visitors can explore the wreck's structure and the abundant marine life around it in clear water. The Windjammer is part of the park's Maritime Heritage Trail, which interprets shipwrecks in the Dry Tortugas. Because it lies near Loggerhead Key, away from the main ferry stop at Garden Key, reaching it usually requires a private boat, and conditions must be suitable for safe snorkeling or diving.

Reaching Loggerhead Key takes more effort than visiting the main attraction at Garden Key, because the regular ferry from Key West serves Garden Key and Fort Jefferson, not Loggerhead. To get to Loggerhead Key, you generally need a private boat, or, for very experienced and well-prepared paddlers, a kayak crossing of the open water between the islands, which should not be underestimated. As a result, Loggerhead sees far fewer visitors and offers greater solitude. The island has no services, docks for large vessels, or facilities beyond the lighthouse structures, so anyone visiting must be completely self-sufficient, bringing all their own water, food, gear, and safety equipment, and must carefully check weather and sea conditions, since crossings can become rough. For those able to reach it, the reward is a remote, beautiful island with a historic lighthouse and superb snorkeling.

A lighthouse was built on Loggerhead Key because the waters of the Dry Tortugas were notoriously dangerous for ships. The area is surrounded by reefs, shoals, and shallow banks that wrecked many vessels over the years, and although Garden Key already had a light, it was not tall or powerful enough to adequately warn mariners away from all the hazards. The much taller Loggerhead Key lighthouse was constructed in the 1850s to provide a stronger, more effective warning, its height allowing its light to be seen from far greater distances across the sea. It has guided ships safely past the reefs for well over a century and remains an important navigational landmark. The lighthouse stands as a reminder of the maritime dangers of this remote region and the many shipwrecks that gave the surrounding waters their treacherous reputation.
