Dry Tortugas National Park
Florida
Dry Tortugas National Park, located about 68 miles west of Key West, Florida, is a unique blend of natural and historical treasures. The park encompasses seven small coral islands, with the centerpiece being Fort Jefferson, the largest brick masonry structure in the Western Hemisphere, built with over 16 million bricks. These islands are part of the westernmost Florida Keys and are renowned for their undisturbed coral reefs, diverse sea life, and significant bird breeding grounds. Visitors can explore the massive but unfinished coastal fortress, snorkel in crystal-clear waters teeming with marine life, and enjoy activities like camping at the Garden Key campground, kayaking, and birdwatching. The park's ecosystem remains largely pristine due to its remote location and limited accessibility by boat or seaplane. Dry Tortugas is also part of the Everglades & Dry Tortugas Biosphere Reserve, highlighting its ecological importance. The islands themselves are dynamic, with shifting landmasses shaped by tides and hurricanes, offering a rare glimpse into a largely untouched tropical environment combined with rich historical artifacts.
ヒント: The best time to visit Dry Tortugas National Park is during the dry season, typically from November to April, when weather conditions are most favorable. Visitors should consider booking boat or seaplane trips well in advance due to limited access. Camping is available but restricted to eight primitive sites on Garden Key, so reservations are recommended. Bring snorkeling gear to explore vibrant coral reefs, and be prepared for limited facilities by packing essentials. Use designated mooring buoys if arriving by boat, and respect protected marine areas where fishing and anchoring are restricted.

歴史
Construction of Fort Jefferson began in 1846 as a coastal fortress intended to protect the strategic shipping channels in the Gulf of Mexico.
The fort remained unfinished but became one of the largest brick masonry structures in the Western Hemisphere.
During the Civil War, it served as a Union military prison.
Over time, the surrounding islands have changed shape and size due to natural forces like hurricanes and shifting water levels.
In 1935, the Dry Tortugas were designated a national monument, and later in 1992, they became a national park.
The area was recognized by UNESCO in 1976 as part of the Everglades & Dry Tortugas Biosphere Reserve due to its ecological significance.
