Islands and cays near Fajardo
Cayo Icacos
The largest of the Cordillera cays, Cayo Icacos is the classic Fajardo day trip: a strip of white sand and warm, clear water just offshore, uninhabited and quiet, with snorkeling right off the beach. There is no ferry and nothing built on it, which is exactly the appeal. You bring the day with you and the cay supplies the water.

What Cayo Icacos is
Cayo Icacos is the biggest island in the Cordillera, the chain of small cays scattered off Fajardo's northeastern coast. It is uninhabited and undeveloped, ringed by pale sand and shallow, exceptionally clear water. That combination, easy to reach yet completely natural, is why it tops most day-trip lists. It also sits within the protected La Cordillera nature reserve, so the same wildness that makes it beautiful comes with a responsibility to tread lightly.
How to visit
There is no public ferry to Cayo Icacos; the only way out is by boat. Most visitors go by catamaran day sail, private charter, or water taxi from the Fajardo marinas, often setting off near Las Croabas. The crossing is short, and many trips fold in other cays or a snorkeling stop along the way, so it is easy to make a full, relaxed day of it.
Snorkeling and the water
The draw in the water is the clarity. Sheltered, shallow areas and nearby reef make for easy, rewarding snorkeling, at its calmest in the summer months. For how it compares with the area's other spots, see our snorkeling guide. The neighboring private island and its tiny cay, Palomino and Palominito, are often part of the same kind of trip.
What to know before you go
- Bring everything. No facilities means water, food, sun protection, and shade are on you.
- Pack snorkel gear. There is nothing to rent on the cay itself.
- Use reef-safe sunscreen to protect the shallows and reef you came to see.
- Leave no trace. This is a protected reserve; carry out every bit of what you carry in.
