Top Snorkeling Spots in Islamorada
1. Alligator Reef Lighthouse – A Must-Visit Snorkeling Site
Alligator Reef is one of the most well-known snorkeling destinations in the Florida Keys. Located about four miles offshore, this vibrant coral reef is home to over 500 species of marine life. Expect to see schools of parrotfish, angelfish, barracudas, and nurse sharks, as well as some of the healthiest coral formations in the region.
The lighthouse itself is a historic landmark, standing over the remains of the USS Alligator, a shipwreck from the 1800s. With visibility often exceeding 50 feet, this reef offers some of the clearest waters for snorkeling in the area.
2. Cheeca Rocks – A Beginner-Friendly Coral Garden
If you’re looking for shallow-water snorkeling in Islamorada, Cheeca Rocks is an excellent choice. Situated just offshore, this reef is a protected marine sanctuary, meaning you’ll find an abundance of marine life in a calm, controlled environment.
At depths ranging from 5 to 20 feet, this spot is perfect for families and beginner snorkelers. Keep an eye out for colorful sponges, sea fans, and reef fish, as well as the occasional southern stingray gliding across the sandy bottom.
3. Hens and Chickens Reef – A Lesser-Known Snorkeling Gem
For those seeking a less crowded snorkeling experience, Hens and Chickens Reef is a fantastic choice. This reef is known for its unique coral formations, which resemble a cluster of hen and chick shapes (hence the name).
Here, you’ll find brain corals, sea turtles, moray eels, and even the occasional reef shark. Because it’s located slightly farther offshore, the waters are exceptionally clear, making it a favorite among underwater photographers and marine life enthusiasts.
4. Indian Key Historic State Park – Snorkeling with a Touch of History
Unlike the offshore reefs, Indian Key offers a unique mix of shallow-water snorkeling and historical exploration. Located just a short kayak trip from Islamorada, this uninhabited island was once a bustling 19th-century wrecking village. Today, snorkelers can explore seagrass beds and remnants of old shipwrecks, spotting conchs, sea cucumbers, and juvenile fish hiding among the rocks.
Because it’s part of a state park, Indian Key also provides opportunities for hiking and learning about Florida Keys history, making it a well-rounded destination for nature lovers.
The Best Time for Snorkeling in Islamorada

A few tips for planning your snorkeling trip:
