You’re standing on the deck of a catamaran, the wind is whipping your hair into a bird's nest, and the salt spray is basically exfoliating your face whether you like it or not. Ahead, there’s nothing but a thin, blindingly white line on the horizon. That’s Klein Curacao. It’s a tiny, uninhabited speck of rock and sand about 15 miles off the southeast coast of the main island. Most people think a Klein Curacao boat trip is just a standard beach day with an open bar. It’s not. If you go in with that mindset, you’re going to be either wildly disappointed or spectacularly sunburnt.
Honestly, the boat ride is the first thing that catches people off guard. The Caribbean Sea looks calm from the shore of Mambo Beach, but once you hit the open water heading east-southeast, you’re fighting the currents. It’s choppy. Sometimes it’s "I should have taken that Dramamine" choppy. You’ll see tourists clutching the railings like their lives depend on it while the crew casually flips burgers on a charcoal grill at the back of the boat. It’s a trip of extremes.
Why the Klein Curacao Boat Trip is Actually a Test of Endurance
The journey takes anywhere from 45 minutes to two hours depending on what you’re riding. If you book a powerboat like those operated by Powerboat Caribbean, you’re going to bounce. Hard. It’s a thrill, sure, but your glutes will feel it the next day. On the flip side, the larger catamarans—think BlueFinn Charters or Miss Ann Boat Trips—offer a more stable, "sip a punch and relax" vibe, but they take longer to fight the wind.
The wind is the real boss here. Because the island is flat—the highest point is barely a few meters above sea level—there’s nothing to break the trade winds. You’ll arrive at this pristine, postcard-perfect beach, but the moment you step off the boat, you realize the sun is relentless. There are a few palapas (straw umbrellas), but they get claimed faster than a lounge chair at a Vegas pool. If your boat doesn’t have a beach house or a dedicated shaded area, you’re basically an ant under a magnifying glass for six hours.
The Lighthouse and the Ghostly Shipwrecks
Most people come for the water, which is a shade of blue that feels like it’s been Photoshopped in real life. But the real soul of the island is inland. You’ve got to walk to the pink lighthouse. It’s iconic, crumbling, and slightly eerie. Built in 1850 and then rebuilt after a devastating hurricane, it stands as a sentinel over a landscape that looks more like Mars than the Caribbean.

Keep walking past the lighthouse to the windward side of the island. This is where the ocean gets angry. This is where the Maria Bianca Guidesman, a massive oil tanker, met its end in the 1980s. Today, it’s a rusting, orange skeleton being slowly eaten by the salt and the waves. It’s a stark contrast to the turquoise serenity of the leeward side where your boat is anchored. There’s a smaller, more recent shipwreck nearby—a luxury yacht that lost its engines and washed up. It serves as a grim reminder that the waters around here don’t play nice.
Survival Tips the Tour Operators Don't Always Mention
Let’s talk logistics. You need to pack differently for a Klein Curacao boat trip than you would for a trip to Grote Knip or Cas Abao.
- Footwear is non-negotiable. The sand is soft near the water, but the interior of the island is sharp volcanic rock and dried coral. If you try to walk to the shipwrecks in flimsy flip-flops, you’re asking for a punctured sole or a twisted ankle. Bring sturdy water shoes or even sneakers you don't mind getting salty.
- The "Reef Safe" Lie. Many people buy "reef safe" sunscreen that actually contains boatloads of chemicals. Look for non-nano zinc oxide. The reef at Klein Curacao is one of the healthiest in the Dutch Caribbean, and the sea turtles—which are everywhere, by the way—don't need your oxybenzone in their lungs.
- Hydration vs. The Open Bar. Most trips include an open bar. It’s tempting to start the rum punches at 10:00 AM. Don't. Between the salt air, the intense UV index (which often hits 11+ here), and the motion of the boat, you will dehydrate faster than a prune. Drink two waters for every alcoholic beverage. Your head will thank you when you’re heading back to Willemstad at 4:00 PM.
The snorkeling is, frankly, world-class. You don't even have to go far. Just off the drop-off, the sea floor plunges into the deep blue, and that’s where the big stuff hangs out. You’ll almost certainly see green sea turtles grazing on the seagrass. They’re used to humans, but don't be that person who tries to touch them. It’s illegal, it’s stressful for the animal, and honestly, it’s just tacky.
Choosing Your Vessel: Catamaran vs. Motorboat
This is where people usually mess up their booking. You have to decide what kind of person you are.

If you want the "luxury" experience, you go with a company that has a permanent structure on the island. Bounty Adventures and Miss Ann have beach houses with actual toilets, showers, and buffet setups. This is huge. If you’re on a smaller boat with no shore facilities, you’re peeing in the ocean and eating a lukewarm sandwich on the sand. For some, that’s the adventure. For others, it’s a nightmare.
Then there’s the "Mermaid." The Mermaid Boat Trips vessel is a large, sturdy motor cruiser. It’s not "sleek" like a catamaran, but it cuts through the waves instead of riding over them. They have the most established infrastructure on the island, including a massive shade porch. If you have kids or older family members, this is usually the smartest play.
The Cost of Paradise
Expect to pay between $110 and $160 per person. It sounds steep for a day trip. However, when you factor in the fuel (which is astronomical in Curacao), the breakfast, the BBQ lunch, the gear, and the open bar, the margins for these operators aren't as wide as you’d think. You're paying for the access. You can’t get there any other way unless you have a private yacht or a very brave friend with a Boston Whaler.
The Reality of Sea Sickness
I’ve seen it happen a dozen times. Someone shows up in a designer bikini, ready for the "Gram," and thirty minutes into the channel crossing, they’re green. The trip to Klein Curacao is an upwind battle. The boat will pitch and roll.

If you’re prone to motion sickness, take your medication an hour before you board. Once you feel sick, it’s too late. The return trip, however, is a dream. You’re going downwind, surfing the swells, and usually, that’s when the party starts. The music gets louder, the drinks flow faster, and the mood lightens as the sun begins to dip.
Is it worth it?
People ask if it’s worth losing an entire day of a Curacao vacation to see a tiny island. The answer depends on your tolerance for nature. If you want a manicured beach with a DJ and sushi service, stay at Jan Thiel. Klein Curacao is raw. It’s a place where you can feel the isolation of the Caribbean. There’s something deeply humbling about standing at the foot of that decaying lighthouse, hearing nothing but the wind and the crashing waves of the Atlantic side, realizing that you’re just a tiny speck on a tiny speck in the middle of a very big ocean.
Actionable Steps for Your Klein Curacao Trip
- Book at least a week in advance. The popular boats like BlueFinn and Mermaid fill up fast, especially during the high season (December through April) and Dutch school holidays.
- Check the wind forecast. Use an app like Windguru or Windy. If the swells are predicted to be over 2.5 meters, and you have a weak stomach, maybe reschedule.
- Pack a "Dry Bag." Even on the big boats, things get wet. A small 10L dry bag for your phone, camera, and a dry shirt is a lifesaver.
- Go to the lighthouse early. Don't wait until after lunch when the heat is at its peak. Head there as soon as you get off the boat to beat the temperature and the crowds.
- Look for the dolphins. They love to play in the wake of the boats crossing the channel. Keep your eyes peeled on the way over; they often appear when you least expect it.
The island doesn't offer much in the way of "activities" beyond what you bring with you. It’s about the silence, the water, and the weird, haunting history of the place. It’s the longest beach in Curacao, and because it’s so remote, it remains the cleanest. Just leave it that way. Take your trash back to the boat. The island has enough shipwrecks; it doesn't need your plastic bottles.
