Hidden National Parks in Florida You've Never Heard Of (But Need to Visit)
When most travelers think of the Florida Keys, images of Key West's vibrant nightlife, scenic drives along the Overseas Highway, and fresh seafood immediately come to mind. However, hidden within this tropical paradise are two of America's most underrated national parks: Dry Tortugas and Biscayne. These natural treasures offer experiences you simply won't find anywhere else in the United States.
While millions flock to Everglades National Park each year, its aquatic siblings remain relatively undiscovered. Dry Tortugas, located 70 miles west of Key West, and Biscayne, just south of Miami, are predominantly underwater parks that protect some of Florida's most pristine marine ecosystems.
From exploring a massive 19th-century fort surrounded by crystal-clear waters to snorkeling among shipwrecks on an underwater archaeological trail, these parks offer adventures that combine history, nature, and aquatic exploration in ways you won't experience elsewhere.
Florida's hidden parks are perfect for crowd-free visits — if you're looking for more strategies to escape the tourist masses, check out our guide on Love National Parks But Hate Crowds? — packed with proven tactics for any season.
Dry Tortugas National Park - An Isolated Gem
Dry Tortugas National Park is truly one of America's most unique and remote national parks. Comprising seven small islands and the surrounding waters, this park is located approximately 70 miles west of Key West in the Gulf of Mexico. The park's name comes from the abundant sea turtles ("tortugas" in Spanish) discovered by explorer Ponce de León in 1513, with "dry" added to warn sailors of the lack of fresh water.
What makes Dry Tortugas extraordinary is its remarkable isolation. As one of the most remote national parks in the United States, it receives only about 60,000 visitors annually. This isolation has preserved both its historical structures and marine environment in exceptional condition.
The centerpiece of the park is the massive Fort Jefferson, one of the largest coastal forts ever built. Construction began in 1846 but was never fully completed despite over 30 years of work. The fort's 16 million bricks form an imposing hexagonal structure that once housed soldiers, prisoners (including Dr. Samuel Mudd, imprisoned for treating John Wilkes Booth), and massive cannons.
Beyond its historical significance, Dry Tortugas is a paradise for marine life. The park protects 100 square miles of some of the most pristine coral reefs and seagrass communities in the Florida Keys, with visibility often exceeding 100 feet.
Biscayne National Park - The Aquatic Paradise
Just a short drive from the urban sprawl of Miami lies Biscayne National Park, one of America's most unusual national treasures. Unlike most national parks known for their mountains, forests, or canyons, Biscayne is 95% underwater. This 173,000-acre park protects a rare combination of aquamarine waters, emerald islands, and fish-bejeweled coral reefs.
Established in 1968 and designated as a national park in 1980, Biscayne was created to protect the northern section of the Florida Reef, the third-largest coral reef system in the world. The park encompasses the northernmost section of the Florida Keys.
What truly distinguishes Biscayne is its underwater landscape. The park protects four distinct ecosystems: the shoreline mangrove swamp, the southern portion of Biscayne Bay, the northernmost islands of the Florida Keys, and the beginning of the Florida Reef.
One of Biscayne's most unique features is the Maritime Heritage Trail, an underwater archaeological trail that connects six shipwrecks spanning nearly a century of maritime history.
