Loggerhead Key is the largest and most remote island in the Dry Tortugas, known for its untouched beauty and rich ecological history. With its iconic black-and-white lighthouse rising above white-sand shores and turquoise shallows, the island feels like a Caribbean oasis hidden 70 miles off Key West.

​

Named for the abundant loggerhead sea turtles that nest here, Loggerhead Key has long been a sanctuary for wildlife. Its surrounding reefs are some of the healthiest and clearest in North America—vibrant coral gardens, tropical fish, and shallow snorkeling sites perfect for all experience levels.

​

The island was once home to the historic Carnegie Laboratory for Marine Biology, a pioneering research station in the early 1900s. Today, visitors can explore its scenic beaches, swim in crystalline waters, and enjoy unparalleled solitude available only by private charter.

A stop at Loggerhead Key offers guests an intimate and serene experience—no crowds, no noise, just pure natural beauty in one of the most extraordinary marine environments in the world.
