Private Islands Near Puerto Rico: The Complete Boat Guide
By Boating Puerto Rico Team · June 2026 · 8 min read
Puerto Rico sits at the center of a remarkable archipelago. Scattered across the turquoise waters of the eastern Caribbean within two hours of Fajardo are more than a dozen uninhabited or sparsely inhabited islands, cays, and islets — most with no road access, no public ferry, and no facilities of any kind. They are, in the most practical sense, private islands available only to those who arrive by boat.
These are not tourist destinations in the conventional sense. There are no hotels, no restaurants, no admission gates. When you anchor off one of these cays, step onto the sand, and look back to see nothing but open water in every direction, the island is yours — at least for the afternoon. Private yacht charter from Marina Puerto del Rey in Fajardo is the only realistic way most visitors will ever set foot on them.
This guide covers the best uninhabited and secluded islands reachable by private boat from Fajardo, what makes each one worth visiting, and what to do when you get there.
The Islands at a Glance
The cays described below fall into two geographic clusters: the near islands (15 to 20 minutes from Fajardo) that are ideal for half-day charters, and the Culebra archipelago (1.5 to 2 hours away) that rewards a full day or overnight trip with some of the most extraordinary marine environments in the Caribbean.
The Near Islands: 15 to 30 Minutes from Fajardo
Icacos Cay (Cayo Icacos)
Most Popular
Distance from Fajardo~15 minutes
AccessPrivate boat only
Best ForSwimming, snorkeling, floating
Icacos is a narrow sandbar rising from the Caribbean about two miles northeast of Fajardo. It is uninhabited, has no facilities, and can only be reached by private vessel. The water surrounding Icacos is the classic image of the Caribbean: turquoise, crystal-clear, calm, and warm, with shallow sandy bottom extending 30 to 50 meters from shore. Snorkeling the reef on the eastern side reveals parrotfish, angelfish, nurse sharks, and if you are fortunate, sea turtles. On the western side, the shallow flat is perfect for the floating mat, paddleboarding, and simply wading in the water with a cold drink. Icacos is the single most-visited destination on all Boating Puerto Rico charters, and deservedly so.
Palomino Island
Half-Day Favorite
Distance from Fajardo~20 minutes
AccessPrivate boat (resort ferry for resort guests)
Best ForBeach, snorkeling, families
Palomino Island sits just offshore from El Conquistador Resort and has a public beach accessible only by water. Non-resort guests reach it exclusively by private vessel. The island offers a long stretch of white sand beach, calm snorkeling waters with excellent coral visibility, and a hillside with views back toward the Puerto Rico mainland. The western anchorage is ideal for floating mat activities; the reef on the eastern shore harbors some of the most accessible coral formations in the Fajardo area. Palomino is an excellent choice for families with children of any age.
Cayo Diablo
Remote & Secluded
Distance from Fajardo~25 to 35 minutes
AccessPrivate boat only
Best ForSolitude, advanced snorkeling
Further offshore and less visited than Icacos, Cayo Diablo is a wilder, more rugged cay with deeper reef diving on its windward side and a more dramatic sense of isolation. The passage to Cayo Diablo involves more open water than Icacos, making it better suited to groups comfortable on a moving vessel. The reward is a near-empty anchorage and reef systems that see far fewer snorkelers than the more popular near-island destinations. Ask your captain about conditions before committing to Cayo Diablo — on certain days, the windward approach makes anchoring challenging.
The Culebra Archipelago: 1.5 to 2 Hours from Fajardo
Culebra is Puerto Rico's most celebrated satellite island — a destination serious enough to merit its own full-day or overnight charter. But Culebra itself is only the beginning. The waters around it contain some of the most pristine uninhabited island real estate in the entire Caribbean basin.
Culebrita
Unmissable
Distance from Fajardo~1.75 hours
AccessPrivate boat only
Best ForTide pools, lighthouse, deserted beaches
Culebrita is the small uninhabited island at the eastern tip of the Culebra archipelago. It is part of the Culebra National Wildlife Refuge, meaning it is federally protected and permanently free of development. The island's most famous feature is "The Jacuzzis" — a series of natural tide pools carved into the island's rocky northeastern point by centuries of wave action. Warm, clear water circulates through the pools in a natural whirlpool effect that feels precisely as the name implies. Higher on the island stands a 19th-century lighthouse ruin with panoramic views of Culebra, Puerto Rico, and on clear days, the U.S. Virgin Islands. The beaches on Culebrita's leeward side are among the most unspoiled in the Caribbean and are accessible only by private vessel from either Fajardo or the town of Dewey in Culebra.
Cayo Norte
Wildlife Reserve
Distance from Fajardo~2 hours
AccessPrivate boat only
Best ForBirdwatching, solitude, photography
Cayo Norte is a larger uninhabited island north of Culebra's main landmass, part of the Culebra National Wildlife Refuge. It hosts nesting colonies of seabirds and brown pelicans, making it one of the best wildlife photography destinations in Puerto Rico's offshore islands. The island itself is off-limits to landing (it is a federally protected nesting site), but anchoring offshore and exploring the surrounding waters by snorkel or paddleboard reveals an ecosystem largely undisturbed by human activity. The clarity of the water around Cayo Norte — particularly on the leeward side — rivals the Maldives for visibility and tropical color.
Cayo Luis Pena
Best Snorkeling in PR
Distance from Fajardo~1.5 hours
AccessPrivate boat only (from Fajardo)
Best ForWorld-class snorkeling and diving
Cayo Luis Pena is widely regarded by marine biologists and underwater photographers as the finest snorkeling destination in all of Puerto Rico — and it is not particularly close. The island sits off the western coast of Culebra and is protected as a no-take marine reserve within the Culebra National Wildlife Refuge. The reef systems surrounding Luis Pena are among the healthiest in the Caribbean, hosting dense coral formations, an extraordinary diversity of reef fish, hawksbill sea turtles in large numbers, nurse sharks resting beneath coral heads, and eagle rays cruising the mid-water column. Because it is a protected marine reserve, fishing is prohibited and motorized watercraft must maintain distance from certain zones — all of which has allowed the ecosystem to recover to near-pristine condition. Access from Fajardo is by private boat only; no public ferry serves Luis Pena. Visiting this island is widely cited by guests as the best snorkeling experience of their lives.
What to Do on Puerto Rico's Private Islands
Snorkeling
The underwater topography around Puerto Rico's offshore cays is extraordinary. Shallow patch reefs, walls, sandy flats with sea grass meadows, and coral bommies all coexist within swimming distance of most anchorages. Every Boating Puerto Rico charter includes snorkeling equipment, and your captain and mate know exactly where to anchor for the best visibility and marine life at each destination.
The Floating Mat
Deployed in calm, warm water off any of the near-island anchorages, the floating mat becomes an island within an island — a platform for reading, napping, jumping in the water, and drifting in the Caribbean with nothing on the agenda. It is, without question, one of the most popular features of any charter day.
Beach Exploration and Tide Pools
Several of these islands — Culebrita especially — reward exploration on foot. The tide pools at Culebrita's Jacuzzis take about 20 minutes to walk to from the anchorage, across a narrow trail through low coastal vegetation. The lighthouse adds another 15 minutes of climbing. On Icacos, a walk around the sandbar's perimeter takes about 30 minutes and rewards with views of the offshore reefs and the distant Puerto Rico mainland.
On-Anchor Meals
Every charter includes sandwiches, wraps, fresh fruit, and snacks. Many groups choose to anchor off a deserted beach and eat lunch aboard the vessel with the island as a backdrop — a distinctly different experience from any restaurant in Puerto Rico. The combination of sea air, warm water, cold drinks, and complete silence except for the sound of the Caribbean moving beneath the hull is something that stays with people long after the trip ends.
Reef-Safe Sunscreen Required
Most of Puerto Rico's offshore cays fall within marine protected areas where chemical sunscreens containing oxybenzone and octinoxate are legally restricted. These chemicals have been shown to bleach coral and disrupt marine ecosystems. Please bring mineral-based (zinc oxide or titanium dioxide) reef-safe sunscreen for every member of your group. This requirement exists at Icacos, all Culebra area cays, and throughout the Culebra National Wildlife Refuge.
Why Private Boat Charter Is the Only Realistic Option
This is not marketing language — it is geography. Of the islands described in this guide, not a single one is served by a public ferry, a water taxi running on a published schedule, or any regular commercial transport from the mainland. Icacos has no pier. Cayo Luis Pena has no pier. Culebrita has no pier. Cayo Norte is federally protected. Cayo Diablo sits in open water without any harbor.
The only way to visit these places — other than owning a private vessel yourself — is to charter one. And the most practical departure point for the entire eastern island chain is Marina Puerto del Rey in Fajardo, which sits directly on the Caribbean side of Puerto Rico's eastern tip, minimizing travel time and maximizing time at the destination.
A full-day charter (8 to 10 hours) from Fajardo can realistically combine two or three islands. A half-day charter (4 to 5 hours) is ideal for one island with ample time to swim, snorkel, eat, and enjoy the floating mat before returning. Overnight charters to Culebra open up the full archipelago — including Luis Pena and Culebrita in the morning when the light is best and other day boats have not yet arrived.
Captain's recommendation: For guests visiting Puerto Rico for the first time and wanting to maximize island variety, we recommend a full-day charter to Culebra that stops at Cayo Luis Pena for morning snorkeling, Culebrita for the Jacuzzis and lighthouse at midday, and Flamenco Beach or Tamarindo for the afternoon. It is a genuinely extraordinary day and represents some of the best island scenery in the entire Caribbean basin.

Are there any private or uninhabited islands near Puerto Rico?
Yes. Puerto Rico's eastern waters contain numerous uninhabited cays accessible only by private boat, including Icacos Cay (15 min from Fajardo), Palomino Island (20 min), Cayo Norte, Cayo Luis Pena, Culebrita, and Cayo Diablo. Most have no public ferry access and no permanent residents. Private charter is the only way to visit them.
How do you get to Icacos Island from Fajardo?
Icacos Cay is approximately 15 minutes by private boat from Marina Puerto del Rey in Fajardo. There is no public ferry or commercial transport to Icacos — the only access is by private vessel. Boating Puerto Rico offers half-day and full-day charters that include Icacos as a primary destination.
What is Cayo Luis Pena and how do you get there?
Cayo Luis Pena is a federally protected uninhabited island off Culebra's western coast, surrounded by the healthiest coral reefs in Puerto Rico. It is accessible only by private boat — approximately 1.5 hours from Fajardo. Snorkeling around Luis Pena is widely regarded as the best in all of Puerto Rico, with sea turtles, diverse reef fish, nurse sharks, and eagle rays commonly encountered.
Can you visit Culebrita from Fajardo?
Yes. Culebrita is 1.5 to 1.75 hours from Fajardo by private boat. The island is uninhabited, part of the Culebra National Wildlife Refuge, and features the famous Jacuzzis tide pools, a 19th-century lighthouse ruin, and pristine deserted beaches. Private charter is the only practical way to reach Culebrita from the Puerto Rico mainland.
What is the best way to visit multiple private islands in Puerto Rico in one day?
A full-day private charter (8 to 10 hours) from Fajardo is the only way to visit multiple uninhabited islands in a single day. A typical full-day Culebra route combines Luis Pena snorkeling in the morning, Culebrita's Jacuzzis at midday, and Flamenco or Tamarindo Beach in the afternoon — all aboard your own private vessel with a professional captain and crew.
