Two famous tropical islands lie just off the coast of Fajardo, but they offer completely opposite experiences. Compare wild nature reserve serenity against luxury resort beach club amenities.
When travelers look east from the clifftops of Fajardo, two distinct landmasses dominate the turquoise horizon. To the northeast lies Cayo Icacos, the largest uninhabited island of the Reserva Natural Arrecifes de La Cordillera. To the southeast lies Isla Palominos (Palomino Island), a 102-acre private tropical retreat leased to the iconic El Conquistador Resort.
While casual visitors frequently lump both destinations together as "Fajardo day trips," choosing the wrong island can completely derail your day. If you arrive at Cayo Icacos expecting a beach bar with frozen piña coladas and restroom facilities, you will be bitterly disappointed by its raw wilderness. Conversely, if you sail to Palomino seeking an untouched castaway sandbar, you may be overwhelmed by jet skis, restaurant pavilions, and hotel crowds.

If your primary motivation is exploring underwater coral reefs and swimming alongside marine wildlife, Cayo Icacos is the undisputed winner. Because Cayo Icacos lies within the 29,653-acre Reserva Natural Arrecifes de La Cordillera, commercial fishing is strictly prohibited and boat anchoring on living coral is outlawed.
The southern reef platform of Icacos (DRNA Zone C) harbors over 83 species of tropical reef fish, massive brain corals, towering sea fans, and endangered elkhorn corals in 18 to 25 feet of crystal-clear water. Snorkelers routinely encounter green sea turtles, spotted eagle rays, and docile nurse sharks right in the shallows. Read our comprehensive Arrecife Icacos snorkeling guide for seasonal visibility conditions.
By contrast, the usable beach shallows of Palomino Island have sustained decades of intense recreational motorized watercraft traffic, resulting in shallower seagrass flats with fewer large coral heads and lower fish density.
Where Palomino Island excels is pure vacation convenience. If you are traveling with elderly grandparents, infants who need air-conditioned nursery breaks, or guests who refuse to spend five hours without access to a clean flush toilet, Palomino provides an effortless experience.
El Conquistador operates high-speed private catamarans that shuttle hotel guests directly from the resort's marina to Palomino's deep-water concrete pier in 12 minutes. Once on the island, guests walk along shaded concrete boardwalks to open-air restaurants serving craft burgers, tropical cocktails, and fresh ceviche. Umbrella and padded chaise lounge rentals are readily available.
However, for independent travelers, you cannot simply walk onto the Palomino resort ferry. You must either be a registered hotel guest at El Conquistador or book a private charter that anchors in the public water buffer off Palomino's southern sand spit.
