Park Comparison
Biscayne vs Dry Tortugas
Two iconic parks, different strengths. Here's how they stack up.
Updated
The Quick Take
Biscayne
Biscayne is the rare national park where Miami's skyline floats on the horizon while you snorkel over the only living coral reef in the continental United States. Within 270 square miles of mostly water, you can paddle mangroves, dive shipwrecks, and camp on Boca Chita's lighthouse island, all 15 miles from a major airport. The trade-off is that you experience this park almost entirely from a boat. If you don't get on the water, you've barely visited; renting a kayak or booking a snorkel charter is essentially mandatory.
Dry Tortugas
Dry Tortugas is what happens when a national park is so logistically inconvenient that it filters out everyone but the committed. Seven coral islands sit 70 miles west of Key West, anchored by Fort Jefferson, a never-finished 19th-century brick fortress with a 50-acre footprint. Reaching it requires a 2.5-hour ferry, a seaplane, or your own boat. The trade-off is exactly that journey: 85,000 visitors per year, eight campsites, no cell service, and a Bortle Class 1 sky make this both pristine and inflexible.
At a Glance
The Crowd Picture
Both parks draw millions, but the crowd experience is different.
Biscayne
Biscayne drew 512,000 visitors in 2024, but most stay around the visitor center and book day-trip boat tours. February through May packs the reefs and Boca Chita's harbor; reserve charters weeks ahead in winter. October sees crowds drop to under 4,500 weekly during hurricane season's tail. Elliott Key's island campground stays quieter than expected even at peak because reaching it requires your own boat or a private charter, which screens out casual visitors automatically.
Dry Tortugas
Dry Tortugas saw only 85,000 visitors in 2024, the second-quietest national park in the contiguous US. The Yankee Freedom ferry caps daily arrivals at around 250 people, who land at Fort Jefferson, eat lunch, snorkel for two hours, and depart. After 3 p.m., when the day-trippers leave, the eight overnight campers essentially have the entire 100-square-mile park to themselves. October is the calmest month at the gate.

Trails & Activities
Both parks are trail-rich, but they cater to different trip styles.
Biscayne
Biscayne is barely a trail park. Six trails total 8 miles, mostly because the park is 95% water. The 2-mile Elliott Key Trail crosses tropical hammock from end to end, the Boca Chita Lighthouse Trail loops a half mile around a 1920s lighthouse, and the rest are best understood as paddle routes or guided snorkel trails through coral. Hiking shoes belong at home; mask, fins, and a kayak are the actual access tools. This is a park you swim, not walk.
Dry Tortugas
Dry Tortugas has even less trail than Biscayne: 2.5 miles, all easy. The Fort Jefferson Trail circles the moat in 1.5 miles, the Garden Key Beach Trail covers a half mile of sand, and the snorkel reef trail extends a mile out into the surrounding water. Once you've walked the fort walls and taken the ranger tour, the rest of the day belongs to swimming, snorkeling, and watching frigatebirds work the thermals overhead. Hiking is not why anyone makes the crossing.
Camping
Biscayne National Park offers significantly more camping options.
