You’re floating in the turquoise water of the Lake Worth Inlet, watching a massive yacht cruise by, and you probably have no idea that just a few yards away, buried under layers of Florida sand and concrete, is a room designed to survive the end of the world.
The peanut island kennedy bunker isn't some urban legend. It’s a real, 1,500-square-foot lead-lined hole in the ground that was once the most secret "office" in the United States.
Honestly, the story of how it got there—and why it’s currently sitting in the dark, gathering dust—is a wild mix of Cold War paranoia and classic Palm Beach history. Most people think it was just a fancy basement. It wasn’t. It was a 10-day rush job built by the Navy Seabees because the President of the United States liked to spend his winters in the sun, and the government realized he was a sitting duck if the Soviet Union decided to launch.
The Secret of Detachment Hotel
Back in late 1960, the Secret Service was sweating. John F. Kennedy had just been elected, and he spent a significant amount of time at his family’s "Winter White House" estate in Palm Beach. The problem? It was December, the Cold War was hitting a fever pitch, and there was nowhere for the Commander-in-Chief to go if a nuclear strike hit the coast.
The solution was Operation Hotel.
In roughly 10 days, the Navy’s construction battalion—the Seabees—built a secret bunker on Peanut Island. They didn't tell the locals what they were doing, obviously. They just told everyone they were building a "munitions storage facility" for the nearby Coast Guard station.
The military called it Detachment Hotel.
It was designed to be reached by helicopter from the Kennedy estate in less than five minutes. Think about that for a second. In the time it takes you to make a cup of coffee, the President could be whisked across the water and dropped into a hole that could withstand a nuclear blast.

What was actually inside?
If you were expecting a luxury suite with a wet bar and silk pillows, you'd be disappointed. This was a military facility through and through.
- The Entry: You’d walk through a blast-hardened tunnel with a 90-degree turn. Why the turn? To minimize the shockwaves from an explosion.
- The Decontamination Room: It had a plywood shower. Seriously. Plywood. If you were exposed to radiation, you’d scrub down here before entering the main chamber.
- The Living Quarters: It was built to hold about 30 people for up to 30 days. It had bunk beds, a tiny kitchen, and a communications room with a direct line to the Pentagon.
- The Rocking Chair: One of the most famous items in the bunker (when it was open for tours) was a replica of JFK’s rocking chair. He had a notoriously bad back, and even in the apocalypse, the man needed his lumbar support.
Why you can't go inside right now
This is the part that bums everyone out. If you hop on a water taxi today and head to Peanut Island, you’ll see the old Coast Guard station and the mound of earth where the bunker is buried, but you’ll also see a lot of "No Trespassing" signs.
The peanut island kennedy bunker has been closed to the public since October 2017.
What happened? Basically, a massive legal and financial mess. For years, the Palm Beach Maritime Museum operated the site. They did a great job restoring it in the 90s, filling it with period-accurate gas masks, K-rations, and that famous red phone. But their lease with the Port of Palm Beach ended, and after some heated disputes over things like liquor licenses and property taxes, the museum was forced to pack up their artifacts and leave.
The bunker was stripped of its furniture. The rocking chair, the maps, the old radios—they were all moved to a smaller museum location at Currie Park in West Palm Beach.
The 2026 Status Update
As of early 2026, there is finally a light at the end of the (blast) tunnel. Palm Beach County officially took over the site and has been working on a massive restoration project.
The Florida Senate recently reviewed funding requests (like LFIR #1695 for the 2026-2027 fiscal year) to pour millions into renovating the entire Coast Guard complex and the bunker. We’re talking about a $4.5 million-plus overhaul. The goal is to turn it into a world-class historical and environmental education center.

Construction is underway, but don't expect to walk through the blast doors tomorrow. The current estimated completion date for the full renovation is June 30, 2028.
The Weird Truths Nobody Mentions
Most history books give you the "Camelot" version of the story. But if you talk to the people who worked on the restoration or studied the original blueprints, things get a little grittier.
For starters, the bunker didn't have a bathroom. Not a real one, anyway. In the event of an actual nuclear winter, the most powerful man in the world would have been using a chemical toilet—basically a bucket with a lid. It really puts the "glamour" of the presidency into perspective.
Then there’s the "Marilyn" rumor. Local legends always love to whisper about Marilyn Monroe visiting the bunker or being part of the evacuation plan. There is zero evidence for this. None. It was a cramped, sweaty, military-grade hole. Not exactly a romantic getaway.
Also, it’s worth noting that the bunker was actually built above the water table. Because Florida is basically a sponge, you can't dig too deep without hitting water. So, they built it at ground level and then piled 25 feet of dirt, lead, and concrete on top of it. It’s an artificial hill, not a deep cave.
Is it worth visiting the island anyway?
Even if the bunker is locked tight, Peanut Island itself is still a gem. It’s 79 acres of man-made land created from dredging material back in 1918.
Today, it's the go-to spot for snorkelers because the rock breakwaters attract tons of tropical fish, manatees, and occasionally small rays. You can walk the entire perimeter of the island on a paved path in about 30 minutes.

If you stand on the southern end of the island, near the abandoned Coast Guard station, you're standing on top of Cold War history. It’s a strange feeling. To your left, people are drinking beer on sandbars and playing music. Directly beneath your feet, there's a lead-lined tomb designed for the end of the world.
How to see it for yourself
If you want to see the exterior of the peanut island kennedy bunker while waiting for the grand reopening, here is the move:
- The Water Taxi: Take the ferry from the Riviera Beach Marina. It’s the easiest way to get there if you don't have your own boat.
- The Currie Park Museum: If you want to see the actual artifacts that were inside the bunker (the red phone, the rations, the chair), head to the Palm Beach Maritime Museum’s mainland location.
- The South Path: Once you land on the island, head south toward the historic Coast Guard station. Look for the large, grassy mound. That’s it. That’s the bunker.
The county is working hard to bring the "Detachment Hotel" back to life. It’s a slow process because you can't just slap a coat of paint on a radioactive-shielded structure from 1961. It needs climate control, ADA accessibility, and serious structural work to handle the thousands of tourists who want to see it.
For now, the bunker remains a silent sentinel of a time when the world was on the brink. It’s a reminder that even in paradise, the reality of global politics can literally be buried just beneath the surface.
What you should do next:
If you're a history buff, don't just wait for the 2028 reopening. Visit the Palm Beach Maritime Museum at Currie Park now to see the original "Detachment Hotel" artifacts while they are still on the mainland. If you're planning a boat trip to Peanut Island, check the Palm Beach County Parks and Recreation website for the most recent updates on construction closures, as parts of the southern end of the island can be restricted during active renovation phases.
