Dry Tortugas National Park
Dry Tortugas National Park Review
This park, 70 miles off the shores of Key West, consists of seven small islands. Tour the fort; then lay out your blanket on the sunny beach for a picnic before you head out to snorkel on the protected reef. Many people like to camp here ($3 per person per night, eight sites plus group site and overflow area; first come, first served), but note that there's no freshwater supply and you must carry off whatever you bring onto the island.
The typical visitor from Key West, however, makes it no farther than the waters of Garden Key. Home to 19th-century Fort Jefferson, it is the destination for seaplane and fast ferry tours out of Key West. With 2½ to 6½ hours to spend on the island, visitors have time to tour the mammoth fort-come-prison and then cool off with mask and snorkel along the fort's moat wall.
History buffs might remember long-deactivated Fort Jefferson, the largest brick building in the western hemisphere, as the prison that held Dr. Samuel Mudd, who unwittingly set John Wilkes Booth's leg after the assassination of Abraham Lincoln. Three other men were also held there for complicity in the assassination. Original construction on the fort began in 1846 and continued for 30 years, but was never completed because the invention of the rifled cannon made it obsolete. That's when it became a Civil War prison and later a wildlife refuge. In 1935 President Franklin Roosevelt declared it a national monument for its historic and natural value.
The brick fort acts as a gigantic, almost 16-acre reef. Around its moat walls, coral grows and schools of snapper, grouper, and wrasses hang out. To reach the offshore coral heads requires about 15 minutes of swimming over sea-grass beds. The reef formations blaze with the color and majesty of brain coral, swaying sea fans, and flitting tropical fish. It takes a bit of energy to swim the distance, but the water depth pretty much measures under 7 feet all the way, allowing for sandy spots to stop and rest. (Standing in sea-grass meadows and on coral is detrimental to marine life.)
Serious snorkelers and divers head out farther offshore to epic formations, including Palmata Patch, one of the few surviving concentrations of elkhorn coral in the Keys. Day-trippers congregate on the sandy beach to relax in the sun and enjoy picnics. Overnight tent campers have use of restroom facilities and achieve a total getaway from noise, lights, and civilization in general. Remember that no matter how you get here, the park's $5 admission fee must be paid in cash.
The park has set up with signage a self-guided tour that takes about 45 minutes. You should budget more time if you're into photography, because the scenic shots are hard to pass up. Ranger-guided tours are also available at certain times. Check in at the visitor center for a schedule. The small office also shows an orientation video, sells books and other educational materials, and, most importantly, provides a blast of air-conditioning on hot days.
Birders in the know bring binoculars to watch some 100,000 nesting sooty terns at their only U.S. nesting site, Bush Key, adjacent to Garden Key. Noddy terns also nest in the spring. During winter migrations, birds fill the airspace so thickly they literally fall from the sky to make their pit stops, birders say. Nearly 300 species have been spotted in the park's seven islands, including frigatebirds, boobies, cormorants, and broad-winged hawks. Bush Key is closed to foot traffic during nesting season, January through September.
