Just a stone’s throw south of Miami’s skyline sits a national park that flips the script on what a “park” even means — because 95% of it is water. Biscayne National Park is where mangrove forests, coral reefs, and 10,000 years of shipwrecks and pirate legends collide in the clearest, bluest water you’ll find on the East Coast. Grab a mask, hop in a kayak, or just settle into a rocking chair at the visitor center — here are 25 facts that prove Biscayne is one of America’s most underrated national treasures.

1) Biscayne National Park is 95% water — one of the only national parks where your feet barely touch land the whole visit.

2) The park protects nearly 173,000 acres, but only about 9,000 of those acres are dry land.

3) It’s home to the northernmost stretch of the Florida Keys, starting with Elliott Key.

4) Elliott Key is the park’s largest island and is technically the first “true” Florida Key made of ancient coral rock.

5) Biscayne preserves part of the Florida Reef, one of the largest coral reef systems on Earth.

6) The park’s highest point tops out at a whopping 9 feet above sea level, found on Totten Key.

7) Its lowest point is 0 feet — sea level itself at the Atlantic Ocean.

8) Biscayne became an official national park on June 28, 1980.

9) It was originally supposed to be part of Everglades National Park, but was carved out separately to ease opposition to the plan.

10) There’s no entrance fee to visit Biscayne National Park.

11) Human history here stretches back more than 10,000 years, starting with Paleo-Indian travelers.

12) The Tequesta people lived along Biscayne Bay for thousands of years before European contact.

13) Legendary pirate Black Caesar reportedly used the islands of Biscayne as a hideout in the early 1700s.

14) In the early 1960s, the CIA reportedly used Elliott Key as a training ground for Cuba-focused operations.

15) Divers and snorkelers can explore the park’s underwater Maritime Heritage Trail, home to six historic shipwrecks.

16) More than 600 species of native fish swim in Biscayne’s waters.

17) Sea turtles are regulars here — loggerhead, green, and hawksbill turtles are all commonly spotted.

18) Manatees glide through the shallows, especially in the calmer bay waters near the mangroves.

19) The endangered elkhorn coral, once one of the Caribbean’s most common reef-builders, still clings to life in the park.

20) Boca Chita Key, with its picturesque ornamental lighthouse, is the most popular island destination in the park.

21) Biscayne Bay averages only about 10 feet deep, making it a giant, gentle playground for paddlers.

22) Aside from the mainland area near the visitor center, you need a boat to reach almost anywhere in the park.

23) Guided eco-adventures — sailing, snorkeling, and paddling trips — depart right from the Dante Fascell Visitor Center.

24) The park sits within sight of downtown Miami, yet feels a world away — locals call it a hidden gem practically in the city’s backyard.

25) Biscayne is officially recognized as one of the largest marine sanctuaries in the entire National Park System.

Whether you’re chasing shipwrecks, paddling past mangroves, or just soaking up that impossibly turquoise water, Biscayne National Park proves that some of the best American wilderness isn’t hiked — it’s swum, sailed, and snorkeled. Come for the coral, stay for the pirate stories, and don’t forget the sunscreen.
