Clearing Up Confusion: Key Biscayne Is Not Part of the Florida Keys
Many travelers mistakenly think Key Biscayne is one of the Florida Keys, but it’s actually the southernmost barrier island along Florida’s Atlantic coast, located just south of Miami. Unlike the Florida Keys, Key Biscayne is part of Miami-Dade County’s barrier islands and offers its own unique coastal experience.
Explore the Northern Upper Keys Starting at Florida City
Heading south from Florida City into the northernmost part of the Florida Keys—known as the Northern Upper Keys—you’ll find fascinating islands such as Soldier Key, Ragged Keys, Boca Chita Key, and Sands Key. These islands are called transitional keys because they are ancient exposed coral reefs, offering unique ecosystems and historical significance for explorers and nature lovers.
Discover Biscayne National Park’s True Florida Keys Islands
The Florida Keys north of Broad Creek lie within Miami-Dade County, while the rest of the Keys are part of Monroe County. These northern islands include the pristine Elliott Key, Adams Key, Rubicon Keys, Reid Key, Totten Key, and Old Rhodes Key — all part of Biscayne National Park. These protected islands boast stunning coral reefs, diverse marine life, and are ideal for snorkeling, scuba diving, and ecotourism activities.
Plan your visit to explore the Northern Florida Keys and Biscayne National Park to experience some of Florida’s most untouched natural beauty and rich marine biodiversity. Whether you’re interested in Florida Keys snorkeling tours, guided scuba diving adventures, or simply exploring historic islands, this region offers something for every traveler
Key Largo Mile Markers Guide | Driving US Highway 1 Through the Florida Keys
Key Largo, the first major island in the Florida Keys, stretches from mile marker 107 to mile marker 91 on the famous Overseas Highway (US Highway 1). When visiting the Keys, locals and visitors alike navigate using these mile markers, making them an essential part of any Florida Keys travel guide.
Starting from Florida City at mile marker 126, the main road—US Highway 1, also known as the Overseas Highway—connects all the stunning islands of the Florida Keys. The highway runs all the way down to Key West at mile marker 0, the southernmost point of the continental United States. Along your drive, green mile marker signs indicate your exact location, helping you find popular spots in Key Largo snorkeling and diving, restaurants, accommodations, and key tourist attractions.
Whether you’re planning a Key Largo vacation, a Florida Keys road trip, or seeking the best scuba diving sites in Key Largo, understanding the Florida Keys mile marker system is very useful. Mile markers help you easily navigate the islands and find popular locations. For example, Sail Fish Scuba in Key Largo is conveniently located near mile marker 103, making it easy to find for your next unforgettable underwater adventure.
Key Largo – The Diving Capital of the World | Sail Fish Scuba
Key Largo is globally recognized as the diving capital of the world, offering some of the most pristine dive sites and world-class scuba diving anywhere on the planet. Spanning over 17 miles long and nearly 7 miles wide, Key Largo boasts an extensive living coral reef system, thousands of historic shipwrecks, and the famous John Pennekamp Underwater Coral Reef State Park, home to the iconic Christ of the Abyss underwater statue.
At Sail Fish Scuba, your premier Key Largo scuba diving shop, we specialize in guided tours to explore these breathtaking dive locations. Experience diving among vibrant coral reefs, abundant marine life, and legendary wrecks. Key Largo’s dive sites offer unmatched variety for every level—from beginner scuba diving in Key Largo to advanced wreck diving adventures.
To enhance Key Largo’s reputation as a top dive destination, two US Coast Guard Cutters, the Bibb and Duane, were intentionally sunk in 1987, creating a thriving artificial reef system. These wrecks rapidly became home to massive coral growth and diverse reef fish, establishing themselves as premier spots for scuba diving tours in Key Largo.
Recognizing the power of shipwrecks in driving dive tourism, local dive shops including Sail Fish Scuba collaborated to raise over a million dollars to bring the famous USS Spiegel Grove—a former Navy vessel—to Key Largo. After years of planning, the USS Spiegel Grove shipwreck was sunk in 2002, creating one of the largest and most spectacular wreck dive sites in the Florida Keys.
Though the Spiegel didn’t sink upright initially and rested on her starboard side at 140 feet, powerful Hurricane Dennis in 2005 shifted the wreck upright, where it remains today—standing tall as an iconic centerpiece for advanced scuba divers seeking unforgettable wreck diving experiences in Key Largo.
Opps! Sorry! We got off topic there for a second. That happens when you get a diver talking about the Florida Keys scuba diving.
Now, back to our story of telling you about your question: How many islands make up the Florida Keys.
Explore Rodriguez Key and Rock Harbor Key Near Key Largo | Florida Keys Boating and Local Anchorages
Just offshore from Key Largo’s southern end, you’ll find Rodriguez Key, an uninhabited island known as a local safe harbor for many hardworking residents who live aboard their sailboats. These locals use Rodriguez Key as a peaceful anchorage spot, regularly dinghying to and from the shore. Rodriguez Key is a hidden gem for boaters exploring the Florida Keys islands near Key Largo.
Traveling south from Key Largo toward Tavernier, the next town down the Overseas Highway, you’ll pass over part of Rock Harbor Key. While often overlooked in many Florida Keys travel guides, Rock Harbor Key is an important part of the chain and lies between Key Largo and Tavernier. Many visitors simply say that Key Largo extends all the way to Tavernier without realizing these unique islands like Rodriguez and Rock Harbor Keys play a key role in the area's geography.
Whether you’re planning a Florida Keys boating adventure, a Key Largo snorkeling trip, or simply want to learn more about the lesser-known islands in the Florida Keys, understanding the location of Rodriguez Key and Rock Harbor Key adds depth to your trip planning and exploration of this beautiful tropical region.

Traveling further south, you’ll encounter a series of narrow islands that barely support the US Highway 1 (Overseas Highway) and are lined with tropical palm and coconut trees.
