The Florida Keys are home to the world’s third largest coral reef system — the Great Florida Reef Tract. The reefs are full of stunning purple sea fans, brain coral, lettuce coral, staghorn coral and parrotfish, blue tang, angelfish, yellowtail snapper and other beautiful underwater creatures. There are plenty of tour companies in Key West — the island chain’s quirky main tourism destination — that explore the coral reef, and range from larger catamaran party boats to smaller experiences and sailing vessels. When visiting the reefs, do not touch the coral and be sure to wear reef-safe sunscreen — or else it can harmful to the already threatened coral reef system.
Many tour companies also include wildlife spotting or kayaking for a full day of fun in the sun. Be aware that the most affordable tours are also often the most crowded. Here are the best snorkeling tour options in Key West.

The 4.5-hour journey includes a relaxing sailing experience with snacks, wine, sodas and beer with morning or afternoon departures from downtown Key West. Then, visitors have an opportunity to kayak some of the mangrove-like canals to see wildlife up close before snorkeling in some of Key West’s beautiful patch reefs of the National Wildlife Refuge, which is filled with colorful fish and sponges. Guides provide an overview of kayaking and snorkeling, plus a history about the area. Viator members noted that the crew was fun and upbeat and they made the trip even more enjoyable.
Best Small Group Snorkel Eco Tour: Java Cat Sail and Snorkel
Those interested in delving deeper to learn more about the ecosystems and local flora and fauna should consider the Java Cat Sail Kayak and Snorkel Charter.

From there, you’ll drop anchor and board kayaks to search the seagrass beds for hermit crabs, jellyfish, starfish, sea cumbers and other marine critters. Then, head back to the boat for a trip to a patch reef for snorkeling with over 600 different species of sea life.
Dolphins and Snorkeling Combo: Shipwreck Snorkel and Wild Dolphin Encounter
