Icacos Island (Cayo Icacos) is an uninhabited cay in the La Cordillera Nature Reserve off the coast of Fajardo, Puerto Rico. There are no hotels, no restaurants, no bathrooms and no ferry — the only way to get there is by private or shared boat, and that boat becomes your shade, your kitchen and your bathroom for the day. This guide covers what Icacos actually is, how to get there, what to do once you're on the sand, and how to choose a trip that fits your group.
What Icacos Island actually is
Icacos is the largest of a string of small cays that sit between Fajardo and Culebra. It is protected as part of the La Cordillera Nature Reserve, which means no development, no vendors and no permanent structures. What you get instead is a long white-sand beach, a shallow sandbar that stretches out into turquoise water, and reef patches close enough to swim to.
Three things people are surprised by:
- There is almost no shade. The vegetation is low scrub. Your boat, a hat and reef-safe sunscreen are your shade plan.
- There are no bathrooms. Boats operating here have a marine head on board. Ask before you book — ours do.
- You can't get there on your own. No ferry, no water taxi. Every visitor arrives on a charter or a tour boat from Fajardo.
None of this is a downside. It's the reason Icacos looks the way it does.
How to get to Icacos Island
You get to Icacos by boat from Fajardo, on the east coast of Puerto Rico. Most trips depart from the marinas along the Fajardo waterfront; ours leave from Marina Puerto Chico.
There are two ways to do it:
Shared tour. A large catamaran with dozens of guests, a fixed schedule and a fixed itinerary. Cheaper per person, and a good fit if you're one or two people who don't mind a crowd.
Private charter. Your own boat, your own captain, your own group. You choose when you leave, how long you stay on the sandbar, and whether you swing by Palomino on the way back. This is what we book.
Where our trips leave from, where to park and how long the drive is from your hotel is all on the Plan Your Day page.
What to do on Icacos
The sandbar. The reason Icacos is on every list. Knee-deep water, white sand under your feet, boat anchored a few yards away. This is where everyone's photos come from.
Snorkeling. Reef patches sit a short swim from the beach. Expect tropical fish, coral heads and, on a good day, a sea turtle or a ray passing through. Gear is on board — you don't need to bring your own.
The beach. Long, empty and quiet on weekdays. Bring a towel, walk to the far end, and you'll usually have it to yourself.
Floating. Honest answer: a lot of people go to Icacos, get in the water, and don't do much else. That's a good plan.
When to go
Time of day. Mornings are usually calmer and less crowded. Shared catamarans arrive mid-morning; a private boat that leaves early gets the sandbar before them.
Day of the week. Weekends bring local boaters. Weekdays are noticeably quieter.
Time of year. High season runs December through April. Summer is hot and still. June through November is hurricane season — trips run all year, but the captain has the final word on conditions, and if the sea says no, we reschedule first and refund if no date works.
We don't promise weather. Nobody honest does. What we promise is a straight answer the morning of your trip.
What to bring
Our trips include lunch, beer, soft drinks, snorkel gear and a Bluetooth speaker — you connect your phone and play your own music.
Bring:
- Reef-safe sunscreen and a hat — the sun on the sandbar is direct
- A towel and a dry bag or zip bag for your phone
- Water shoes if you have sensitive feet
- Motion-sickness tablets if you're prone to it — take one an hour before departure, with food
- A light cover-up for the ride back
- Cash for the captain's tip, if you'd like to leave one
Leave at home: glass, anything you'd be upset to get wet, and expectations of cell service — signal on Icacos is spotty.
Icacos or Palomino?
They're neighbors and most private trips can visit both. Icacos is the sandbar and the empty beach. Palomino is a resort island with a livelier beach and calmer, more protected water on its lee side. If the sea is rough on the Icacos side, your captain may suggest Palomino instead — that's a safety call, and it's a good one. Read more on our Palomino Island page.

Icacos Island FAQ
Is Icacos Island worth it?
Yes, if you want an empty beach, a sandbar and clear water without buildings or crowds. It's not the place for restaurants, shade or a day of amenities — that's Palomino or a resort. People who know what they're getting almost always love it.
How do you get to Icacos Island?
By boat from Fajardo. There's no ferry or water taxi. You book either a shared catamaran tour or a private charter; both depart from the Fajardo marinas.
Is there shade on Icacos?
Very little. The island is low scrub and sand. Plan on your boat, a hat and sunscreen for shade.
Are there bathrooms on Icacos Island?
No. There are no facilities on the island. Boats that operate here have a marine head on board — ask before you book.
Can kids go to Icacos?
Yes. The sandbar is shallow and calm, which is why families like it. Life jackets in kids' sizes are on board; tell us ages when you book.
Do I need to know how to swim?
No. Life jackets are provided and the sandbar is knee-deep. Non-swimmers can float and wade comfortably.
What if it rains in San Juan the morning of my trip?
Rain in San Juan doesn't mean rain in Fajardo — the east coast often has different weather. Your captain makes the call based on sea conditions at the marina, not the forecast for the metro area. If the trip runs, it runs.
What happens if the captain cancels for weather?
We reschedule first. If no date works for you, you get a full refund. There's no arguing with the captain on this one — the sea decides.
Can I bring my own food and drinks?
Lunch, beer and soft drinks are included on our trips. You're welcome to bring extras; no glass on board.
Is there cell service on Icacos?
Spotty. You'll often get a signal on the boat and lose it on the beach. Download your playlist before you leave the marina.
Is a tip expected?
Tips aren't included and aren't required. If your captain and crew made your day, it's appreciated, and cash is easiest.
