The Cayo Icacos reef
The reef sits about 100 meters off the cay's beach in shallow, calm water. It is healthy and accessible, which makes Icacos a reliable snorkel stop on a day trip.

Rays gliding over the sandy patches
The occasional green turtle in the seagrass
Coral heads and reef structure in clear daylight
Gear and guides
Most catamaran and boat tours include mask, snorkel, and fins plus a guided stop. Bring your own mask if you have one for a better fit, and a defog solution.
Best tours for snorkel time
Snorkel focused boat tours and small group catamarans give more reef time than party boats. If snorkeling is the priority, pick a tour that names a guided reef stop.
Go on a calm, sunny day for the best visibility, use reef safe sunscreen, and snorkel in the morning before afternoon winds pick up.
