The hidden national parks of the Florida Keys

Exploring the Hidden National Parks of the Florida Keys: Dry Tortugas vs Biscayne (Complete Guide 2025)

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. What makes these parks truly special is not just their stunning beauty, but their relative isolation from the tourist crowds that dominate other Florida attractions.

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. Whether you're a history buff, a snorkeling enthusiast, or simply seeking solitude in nature, these hidden gems of the National Park System deserve a spot on your Florida Keys itinerary.

In this comprehensive guide, we'll compare these two remarkable parks, help you decide which one (or both!) to visit, and provide all the practical information you need to plan an unforgettable trip to the hidden national parks of the Florida Keys.

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—a fraction of the millions who visit more famous parks like Yellowstone or Yosemite. 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 designed to protect this strategic deepwater anchorage.

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. The crystal-clear waters surrounding the fort offer visibility often exceeding 100 feet, making it a world-class destination for snorkeling and diving.

The park's isolation has also made it a crucial habitat for seabirds. During spring migration, the islands become a critical resting spot for neotropical migrant birds traveling between South America and North America. Birdwatchers can observe magnificent frigatebirds, sooty terns, brown noddies, and masked boobies, among many other species.

Despite its remote location—or perhaps because of it—Dry Tortugas offers an experience of untouched natural beauty and historical immersion that few other national parks can match.

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 (initially as a national monument) 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, starting from the southern tip of Key Biscayne and extending southward to include numerous small keys and reefs.

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. This diversity creates a biological wonderland where over 600 native fish species, numerous bird species, and even threatened animals like the West Indian manatee and American crocodile find sanctuary.

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. These shipwrecks, ranging from a 19th-century wooden sailing vessel to a steel-hulled steamship, offer snorkelers and divers a fascinating glimpse into the area's rich maritime past.

The park also includes several keys (small islands) with their own attractions. Boca Chita Key features a historic lighthouse built in the 1930s by Mark Honeywell, while Elliott Key, the park's largest island, offers hiking trails through tropical hardwood hammocks. Adams Key provides a glimpse into the area's past as a popular recreation spot during Prohibition.

Despite its proximity to Miami—one of America's largest metropolitan areas—Biscayne National Park remains relatively uncrowded, with about 500,000 visitors annually. This makes it a peaceful escape where visitors can experience the natural beauty of the Florida Keys without the crowds typically found in more accessible tourist destinations.

Dry Tortugas vs Biscayne: A Comparison

When deciding which of these hidden Florida Keys national parks to visit, it helps to understand their key differences and similarities. Here's a comprehensive comparison to help you choose the park that best matches your interests and travel style:

Time Needed	Full day minimum (overnight ideal)	Half-day to multiple days
Best For	History buffs, serious snorkelers, solitude seekers, photographers	Casual snorkelers, kayakers, shipwreck enthusiasts, wildlife watchers

Which park should you choose?

Choose Dry Tortugas if:

You're fascinated by historical forts and military architecture
You want truly pristine snorkeling conditions with exceptional visibility
You're seeking a more remote, adventurous experience
You're interested in camping in a truly unique location
You're an avid bird watcher, especially during spring migration
You don't mind spending more for a once-in-a-lifetime experience

Choose Biscayne if:

You're on a tighter budget
You have limited time in the Miami/Keys area

You prefer kayaking through mangroves over open water activities
You want more flexibility in your visit duration and activities

Insider Tip: Can you visit both parks in one trip? Yes, but it requires careful planning. The parks are about 160 miles apart, which means at least 3-4 hours of driving plus a ferry or seaplane journey to Dry Tortugas. A reasonable itinerary would include: Day 1: Explore Biscayne National Park; Day 2: Travel to Key West; Day 3: Day trip to Dry Tortugas; Day 4: Additional day in Dry Tortugas if camping overnight.

How to Get to Dry Tortugas

Reaching Dry Tortugas National Park requires advance planning due to its remote location 70 miles west of Key West. There are only two transportation options available to visitors:

Frequently Asked Questions

Q: Can I visit both parks in one day?
A: While technically possible, it's not recommended. The parks are about 160 miles apart, and Dry Tortugas requires at least a full day. It's better to dedicate at least one full day to each park.

Q: Is it worth visiting these parks if I don't snorkel?
A: Yes! Dry Tortugas offers fascinating history at Fort Jefferson, bird watching, and beautiful views. Biscayne offers island exploration, kayaking, and scenic boat tours. However, snorkeling does enhance the experience at both parks.

Q: What's the best way to avoid seasickness on the Dry Tortugas ferry?
A: Take motion sickness medication at least 30 minutes before departure, stay on the outside deck in fresh air, keep your eyes on the horizon, and avoid alcohol the night before. Consider the seaplane option if you're very prone to seasickness.

Q: Are there restrooms at these parks?
A: Dry Tortugas has composting toilets on Garden Key. Biscayne has restrooms at the mainland visitor center and on Elliott Key, but not on Boca Chita Key or other islands.

Q: Is there cell phone service?
A: Cell service is very limited or non-existent at Dry Tortugas. Biscayne has spotty coverage near the mainland but limited service on the water and islands.

Insider Tip: Download offline maps, guides, and any necessary information before your trip. Take screenshots of reservations and important details. Let someone know your itinerary, especially if camping overnight.

Conclusion

The hidden national parks of the Florida Keys—Dry Tortugas and Biscayne—offer experiences that stand in stark contrast to the typical Florida vacation. While millions of visitors flock to the state's theme parks and popular beaches, these natural treasures remain relatively undiscovered, preserving their pristine beauty and sense of adventure.

Dry Tortugas captivates with its perfect blend of history and nature—a massive 19th-century fort rising from crystal-clear turquoise waters, surrounded by vibrant coral reefs teeming with marine life. The park's remote location, accessible only by boat or seaplane, ensures that those who make the journey are rewarded with uncrowded snorkeling, spectacular bird watching, and stargazing unmarred by light pollution.

Biscayne, though closer to Miami's urban sprawl, remains a world apart—a primarily underwater park protecting a rich tapestry of mangrove shorelines, emerald islands, and coral reefs. Its unique Maritime Heritage Trail offers snorkelers the chance to explore shipwrecks spanning centuries of maritime history, while its islands provide glimpses into the area's past through historic structures and natural landscapes.

What makes these parks truly special is not just their natural beauty, but the sense of discovery they inspire. In an increasingly crowded and connected world, they offer rare opportunities to experience the Florida Keys as they once were—wild, pristine, and full of wonder.

Whether you choose to explore the imposing walls of Fort Jefferson, snorkel among colorful fish in clear waters, paddle through mangrove tunnels, or simply relax on a remote island beach, these parks provide experiences that will stay with you long after your visit.

As you plan your journey to these hidden gems, remember that their preservation depends on responsible visitation. Follow Leave No Trace principles, respect wildlife and historical structures, and consider how your actions impact these fragile ecosystems.

The effort required to reach these parks—whether by ferry, seaplane, or boat—is part of what keeps them special. That extra step beyond the typical tourist path leads to rewards that can't be found elsewhere: solitude among natural beauty, connection with history, and the satisfaction of experiencing some of America's least-visited but most extraordinary national parks.
