The Ultimate Guide to Cayos Holandeses, San Blas Islands

Short answer: the Cayos Holandeses — the Dutch Cays, known locally as Mauki — are the outermost group of the San Blas archipelago, three to four hours of sailing from the mainland. A barrier reef shelters a wide, shallow, white-sand lagoon that sailors call the Swimming Pool. They are too far for a day trip, and that is exactly why there are no crowds.

Cayos Holandeses in San Blas is Located at the furthest edge of the archipelago, bordering the open ocean, the Holandeses Cays (known locally as Mauki) are the islands that sailors whisper about. This is the place you see in your dreams but rarely see on Instagram—because day-trippers can’t get here.

It takes 3-4 hours of sailing to reach them. But once you drop anchor in the “Swimming Pool,” you will realize: This is the best place on earth.

As captains, this is our favorite destination. It is wild, it is silent, and it is the definition of “barefoot luxury.” Here is your insider’s guide to the Crown Jewel.

The “Swimming Pool”: A Natural Wonder

The defining feature of Holandeses is its geography. A massive barrier reef protects the islands from the Atlantic Ocean waves. Behind this reef lies a vast area of shallow, white-sand bottom water that stretches for miles.

Sailors call it “The Swimming Pool.”

• The Water: It is blindingly clear. You can see the shadow of the boat on the sand 20 feet below.

• The Wildlife: Because it is connected to the deep ocean, the marine life here is spectacular. You will often wake up to see spotted eagle rays, nurse sharks (harmless and beautiful), and massive sea turtles swimming right under the trampoline.

• The Protection: Despite being far out, the reef blocks the waves, making this one of the calmest, flattest anchorages in the world. It is perfect for sleeping. San Blas with Kids

Why You Can’t Visit on a Day Trip (And Why That’s Good)

This is the secret to Holandeses’ magic: Distance.

• The Barrier: It is simply too far for the small lanchas to travel in a single day.

• The Reward: This means there are zero day-tour crowds. No loud music, no packed beaches, no “rush hour.”

• The Exclusivity: When you are here, you are usually alone (or sharing the bay with just a few other luxury sailboats). It is the closest you can get to owning a private island. San Blas Private vs. Shared Charter Sailing Experience

The Highlights of the Dutch Cays

1. “BBQ Island” (Mauki) A long, crescent-shaped island with perfect palms and soft sand.

• The Experience: This is our favorite spot for a private beach setup. We bring the paddleboards, the cooler, and the beach chairs. You spend the afternoon reading in the shade while your crew prepares fresh coconuts.

2. The “Outer Reef” Snorkeling Because Holandeses sits on the edge of the deep sea, the coral is healthier and more vibrant here than anywhere else.

• What You’ll See: Massive brain corals, purple sea fans, and schools of snapper and jacks. It is a “live” aquarium. Activities & Water Sports

3. The “Trash-Free” Paradise Because of its remote location and lack of daily tourist traffic, these islands are pristine. The beaches are cleaner, the sand is whiter, and the feeling of “wildness” is real.

The “Hunter-Gatherer” Experience

Holandeses is often where our culinary magic happens. Because we are close to deep water, local Guna fishermen often freedive here for the best catch.

• Sea-to-Table: It is very common for a fisherman to paddle up to the Nomade with lobster or giant crab caught minutes ago on the outer reef.

• The Dinner: Your private chef buys it right there on the deck, and two hours later, you are eating grilled lobster under the Milky Way. You cannot get fresher food anywhere in the world. San Blas Private Chef

Go Further. Stay Longer.

Most visitors to San Blas never see the Holandeses Cays. They stick to the coast. Don’t be “most visitors.”

Book a 6-day charter, tell your captain “Take me to the Swimming Pool,” and wake up in the true crown jewel of the Caribbean.

Frequently asked questions

How far are the Cayos Holandeses from the mainland?

Three to four hours of sailing. There is no shorter route: they sit at the outer edge of the archipelago, on the border of the open ocean.

Can you visit the Cayos Holandeses on a day trip?

No. It is too far for the small lanchas to cover in a single day, so the Dutch Cays are reached only by boats that sleep on board. That distance is the reason there are no day-tour crowds waiting for you when you arrive.

What is the Swimming Pool in the Cayos Holandeses?

The name sailors give to the shallow, white-sand water behind the barrier reef. The reef blocks the Atlantic swell, so the anchorage stays flat, and the water is clear enough to see the shadow of the boat on the sand about twenty feet below.
