The complete guide to Icacos Cay — how to get there, the best snorkeling spots, what marine life to expect, and tips from captains who run this route every week.
Icacos Cay is a small, uninhabited island sitting within the Spanish Virgin Islands chain approximately 45 minutes east of Fajardo by boat. It is one of the most popular day-trip destinations in eastern Puerto Rico, and for good reason: white sand beaches, crystal-clear water, healthy reef snorkeling, and no hotels, restaurants, or crowds to spoil the experience.
What many visitors do not realize is that there is no ferry to Icacos, no bridge, and no public access route. The only way to get there is by boat — which means the quality of your Icacos experience depends entirely on how you get there. This guide explains everything.
Icacos Cay (officially Cayo Icacos) sits approximately 7 nautical miles northeast of Las Croabas and about 10 nautical miles from Marina Puerto del Rey in Fajardo. It is part of the cluster of small cays and islands that make up Puerto Rico's Spanish Virgin Islands — the same chain that includes Palomino, Lobos, Diablo, and the uninhabited cays of the La Cordillera Natural Reserve.
The island itself is about one kilometer long and a few hundred meters wide. It sits low in the water, fringed by white sand on all sides, with crystal-clear shallows that grade into deeper reef structures as you move away from the beach. There are no permanent structures on the island, no fresh water, no electricity, and no shade except from the sea grape trees along the shoreline.
There is exactly one way to reach Icacos Cay: by boat. Here are the options available to visitors.
A private boat charter departing from Marina Puerto del Rey is by far the most comfortable, flexible, and complete way to visit Icacos. You board at the marina, the captain sets your schedule, and you anchor directly off Icacos for as long as you choose. Most guests opt for a 6-hour charter that includes Icacos plus a stop at Palomino Island on the return.
Everything is included on a private charter: licensed captain and mate, fuel, snorkel gear, floating mat, ice, beer, water, sodas, fresh fruit, snacks, and sandwiches or wraps. You are not on a shared tour with strangers — the boat is exclusively for your group.
Small water taxis depart from Las Croabas fishing village, about 10 minutes north of Fajardo. These are typically open skiffs carrying several passengers, with basic seating and no shade. Service is informal, pricing varies, and schedules are not fixed. The ride takes approximately 30 to 45 minutes depending on the vessel.
Water taxis are the lowest-cost option, but you give up comfort, convenience, and any control over your time at the island. You cannot bring a cooler of your preferred drinks, you cannot anchor wherever you want, and you wait for the driver to decide when to leave.
Visitors with their own boat can anchor off Icacos. Marina Puerto del Rey is the primary base for those trailering or with a live-aboard vessel. Be aware that anchoring restrictions apply — do not anchor on coral. Sand-only anchoring and the use of reef-safe technique is required by PRDNER regulations.

Book an Icacos Boat Trip from FajardoThe reef surrounding Icacos Cay is one of the healthiest close to Fajardo. The western side of the island features sandy shallows that transition into a mixed coral and sea grass bed at around 8 to 15 feet — ideal for beginners, children, and anyone getting into the water for the first time. The sand is white and reflective, which makes the water appear even more luminous from the surface.
The eastern and northeastern sides of the island offer more substantial reef structure — brain coral heads, elkhorn coral formations, sea fans, and deeper drop-offs that reach 30 to 40 feet. This is where the larger marine life congregates and where more experienced snorkelers spend most of their time.
Sea turtles are the standout attraction at Icacos. Hawksbill turtles feed on the sea grass beds on the western shelf, and our captains know the specific anchor spots where you are most likely to encounter them within the first few minutes of being in the water. This is not a zoo encounter — the turtles are wild, free, and completely indifferent to swimmers.
Beyond turtles, guests regularly see spotted eagle rays cruising the reef edge, moray eels tucked into coral crevices, dense schools of blue tang and parrotfish, queen angelfish, sergeant majors, and the occasional Caribbean reef shark at depth. Visibility on calm days runs 40 to 60 feet — good enough that you can see the reef from the surface and watch fish feeding on the coral below.
The beach at Icacos is consistently beautiful — fine white sand, shallow warm water, and no beach chairs to rent or cocktails to buy. It is a genuinely wild island beach. Guests regularly spend an hour on the sand between snorkel sessions, and the floating mat we bring on every charter makes it easy to lounge in the shallows directly off the boat.
The protected western anchorage at Icacos is calm enough to float, paddle, and play in the water with no current concerns. The floating mat is deployed off the stern of the boat and guests use it as a platform to relax between swims. Some guests bring their own paddleboards, which can be arranged in advance.
Icacos pairs well with Palomino Island, which sits to the southwest and offers its own beach and reef. Many guests combine both on a 6- or 8-hour charter. For those with a full day, the charter can extend to Culebra — adding the Luis Pena Channel Reserve to the itinerary for the most complete snorkeling day trip available from Fajardo.
Best months to visit Icacos: November through April for flat water and best visibility. June and July can also be excellent on calm mornings. The cay is accessible year-round but summer afternoons can bring brief squalls. Our captains monitor conditions daily and will always advise on timing.
