If you scroll through Instagram for more than five minutes looking at Puerto Rico, you’re going to see it. A rusted, hulking mass of iron sitting right in the turquoise surf, covered in neon graffiti and peeling layers of history. This is the painted tank at Flamenco Beach. Most tourists treat it like a quirky backdrop for a bikini shot. They climb on it, pose with it, and move on to their next piña colada.
But honestly? That tank is a scar.
It’s a remnant of a 60-year occupation that turned the tiny island of Culebra into a literal target. For decades, the United States Navy used this pristine stretch of white sand as a firing range. They dropped bombs. They tested ship-to-shore missiles. They left behind ghosts in the form of M4 Sherman tanks and unexploded ordnance. Today, the painted tank at Flamenco Beach stands as a weirdly beautiful middle finger to that era—a piece of military hardware reclaimed by art and salt air.
The Messy History of Culebra’s Military Past
The Navy didn't just stumble upon Culebra. They arrived in the early 1900s, but things got real in 1939. With World War II looming, the U.S. decided Culebra and its neighbor, Vieques, were the perfect spots for "The Atlantic Fleet Weapons Range."
Imagine living in a paradise and suddenly having battleships park off the coast to play target practice. That was life for the Culebrenses. By the time the 1970s rolled around, the residents had enough. They started a series of non-violent protests that were, frankly, incredibly brave. They occupied the beaches during live-fire drills. They stood in the way of the world's most powerful military.
By 1975, the Navy finally packed up and left Culebra. But they didn't take everything with them.

The painted tank at Flamenco Beach stayed behind because, quite simply, it was too heavy and rusted to bother moving. It was an M4 Sherman tank, likely used for target practice. Over time, the saltwater ate through the hull. The local community and visiting artists decided that if they couldn't get rid of the reminder of war, they would transform it.
From Camouflage to Canvas
The transformation of the tank is what makes Flamenco Beach so surreal. One year it might be painted like a giant fish. The next, it’s covered in political slogans demanding independence or peace. There is no "official" artist for the tank. It’s a rotating gallery of whoever shows up with a spray can and a vision.
The most famous iterations often feature "Paz" (Peace) written in bold letters. It’s a vibe that feels very specific to Puerto Rico—turning a tool of destruction into something vibrant and full of life. It’s also a testament to the resilience of the ecosystem. Despite the decades of bombing, Flamenco Beach remains one of the top-rated beaches in the world. The water is so clear it looks fake.
What Most People Get Wrong About Visiting
You’ve probably heard that Culebra is "untouched." That's a stretch. It’s definitely quieter than San Juan, but the painted tank at Flamenco Beach is a major draw. If you want a photo without twenty other people in the frame, you have to be smart about it.
First off, don't just take the ferry and expect a cakewalk. The ferry from Ceiba is notorious. It’s cheap, sure, but it’s also prone to delays, cancellations, and the "Mareo" (seasickness) that comes with crossing the Virgin Passage. If you can swing it, fly. Small planes from Isla Grande or Luis Muñoz Marín International Airport take about 15 minutes. It’s worth every penny for the view alone.

Once you’re on the island, you’ll need a Jeep or a golf cart. Most people opt for the golf cart. It’s fun until you’re trying to go up a steep hill with four people and a cooler full of Medalla beer.
Finding the Tanks (Yes, There’s More Than One)
Wait, did you think there was only one?
The main painted tank at Flamenco Beach is the one in the water. That’s the icon. But if you walk further down the beach, past the crowds, you’ll find another one tucked into the brush. This one feels a bit more eerie. It’s not as "pretty" as the water tank. It’s overgrown, rusting into the sand, and serves as a starker reminder of what this place actually was.
People often ask if the tanks are dangerous.
Well, they are rusted metal. Tetanus is a real thing. Sharp edges are everywhere. And while the beach itself has been cleared of "unexploded ordnance" (UXO), the local authorities still advise against wandering too deep into the fenced-off "Reserva Natural" areas. Basically, stay where people are. Don't go digging for souvenirs in the restricted brush.

Why the Tank Still Matters in 2026
You might think that after 50 years, the novelty would wear off. It hasn't. The painted tank at Flamenco Beach is more relevant now because of the ongoing conversation about Puerto Rico’s status and its relationship with the mainland U.S.
When you see a child playing on a tank, it’s a jarring image. It forces you to think about the intersection of tourism and colonialism. Puerto Rico is a destination, but it’s also a home with a complicated, often painful history. The tank is the physical manifestation of that complexity.
Environmental Recovery
Interestingly, the tank has become a sort of artificial reef. Small fish dart in and out of the rusted underside. It shows how nature eventually wins. The Navy used this place to test how to break things, but the ocean and the sun have spent the last five decades putting it back together in their own way.
The sand at Flamenco is incredibly fine and white because it’s mostly pulverized coral. It doesn't get hot, even in the midday sun. Walking past the painted tank at Flamenco Beach with your toes in that cool sand is an experience you won't get anywhere else on earth. It’s beautiful, tragic, and hopeful all at once.
Actionable Tips for Your Culebra Trip
If you’re planning to visit the painted tank at Flamenco Beach, don't just wing it. This isn't a resort beach where everything is handed to you.
- Book the Ferry Early: If you aren't flying, buy your ferry tickets weeks in advance via the Puerto Rico Ferry website. Don't show up at the Ceiba terminal hoping for a miracle.
- Bring Cash: While many places take cards or Ath Movil, Culebra is small. Some food kiosks (kioskos) near the beach entrance might be cash-only or have "broken" machines.
- Arrive Before 10 AM: The crowds from the day-trip catamarans arrive around 11:00 AM. If you want that pristine shot of the painted tank at Flamenco Beach without a sea of people, get there early.
- Pack Out Your Trash: This is a wildlife refuge. There are turtles nesting nearby. Don't be that tourist who leaves a plastic bottle on the tank.
- Sunscreen Choice: Use reef-safe sunscreen. The ecosystem here is fragile and already recovering from a lot. Don't add chemical bleaching to its list of problems.
The real way to experience this place is to stay overnight. When the last ferry leaves at 5:00 PM, the island changes. The vibe gets local. The stars come out. And the painted tank at Flamenco Beach sits quietly in the dark, a silent witness to a history that Culebra refuses to forget.
Go for the photo. Stay for the story. Respect the island. That’s how you truly see Culebra.
Practical Next Steps for Your Journey
- Check the weather and tide charts: The tank looks best and is easiest to photograph during low tide when more of the structure is exposed.
- Download offline maps: Cell service on Flamenco Beach can be spotty. Make sure you have your rental return info and accommodation address saved.
- Support the local economy: Eat at the small spots in Dewey (the main town). The "Pinchos" (meat skewers) at the beach kiosks are great, but the real culinary gems are in town.
- Look into the Culebra Foundation: If you want to learn more about the civil disobedience that led to the Navy's departure, visit the local museum (Museo de Culebra). It adds a layer of meaning to your trip that a souvenir shop can't provide.
