Most people think the "End of the World" is Ushuaia. It isn't. If you look at a map of the jagged tip of South America, your eye probably stops at Tierra del Fuego, but there is a wild, forgotten shard of rock sitting further east across the Le Maire Strait. That is Isla de los Estados. It’s a place where the Atlantic and Pacific oceans don't just meet—they collide in a violent, foaming mess of riptides and unpredictable surges.
I’m telling you, this isn't a vacation spot for the faint of heart. Honestly, it’s barely a vacation spot at all.
Access is so restricted that most Argentines will never set foot there in their entire lives. It is a National Nature Reserve, strictly managed by the Argentine Navy, and honestly, the weather is so atrocious that the island seems to want to kick you off the moment you arrive. We are talking about over 250 days of rain a year. Thick, suffocating peat bogs. Mountains that look like broken teeth. It’s beautiful, sure, but it's a "stay away" kind of beautiful.
Why Isla de los Estados is the actual inspiration for Jules Verne
You’ve probably heard of the book The Lighthouse at the End of the World. Jules Verne wasn't just making stuff up. He was fascinated by the San Juan de Salvamento lighthouse, which was built on the eastern tip of Isla de los Estados in 1884.
Back then, the island was a graveyard.
If you were a sailor in the 19th century, this place was your literal nightmare. The currents in the Le Maire Strait can reach speeds that make modern engines struggle, so imagine trying to navigate it in a wooden sailing ship during a gale. Hundreds of ships ended up smashed against the cliffs. The Argentine government realized they had to put a light there, but the original structure was basically a small octagonal wooden shack with a few kerosene lamps. It didn't pulse like a modern lighthouse; it just glowed.
The navy eventually abandoned it because it was too hard to maintain in the relentless wind. They replaced it with the Año Nuevo lighthouse on a nearby islet. But the legend stuck. In the late 90s, a group of French enthusiasts actually went back and rebuilt the original "Verne" lighthouse. It’s there now—a lonely wooden ghost looking out over the water. It feels hauntingly isolated.
The landscape will try to eat your boots
If you expect white sandy beaches, you’re in the wrong hemisphere. Isla de los Estados is a continuation of the Andes mountain range, just submerged and then popping back up out of the sea.

The terrain is a mix of Nothofagus forests—those gnarled, wind-swept southern beeches—and deep, treacherous peat bogs. If you’ve never walked on a peat bog, it’s like walking on a giant, water-soaked sponge that’s trying to steal your shoes. One step is firm; the next, you're waist-deep in freezing mud.
The mosses are vibrant. Electric greens and deep oranges. Because the island was never heavily settled or farmed, the ecosystem is incredibly "pure," but it's also fragile. You’ll find Magellanic penguins, rockhopper penguins, and a massive colony of South American fur seals. The sea lions here are huge. They look like boulders until they start barking at you.
Interestingly, there’s a weird invasive species problem.
Goats and deer.
In the mid-1800s, sailors released them so shipwrecked crews would have something to eat. Now, the goats have completely changed the vegetation in certain areas. It’s a classic case of humans trying to be helpful and accidentally messing up a localized biome. Scientists are still debating the best way to manage them without causing further damage to the soil.
The dark history of Puerto Cook
Life on Isla de los Estados wasn't just hard for sailors; it was a literal prison for others. Between 1899 and 1902, the island housed a military prison at Puerto Cook.
It was a brutal, miserable existence.

Imagine being stuck on a freezing, damp island with no heat, minimal food, and no way to escape. The Strait of Le Maire was a more effective wall than any stone fortress. There was a famous mutiny in 1902 because the conditions were so inhumane. Eventually, the prison was moved to Ushuaia because even the guards couldn't stand the psychological toll of the island’s isolation. When you visit the ruins today—and "ruins" is a generous word for the rotting foundations and the tiny, lonely cemetery—you can still feel that heavy, oppressive atmosphere.
It’s one of those places where the wind sounds like people whispering. Sorta creepy, honestly.
How do you actually get there?
You can't just buy a ferry ticket. You’ve basically got two options:
- Expensive Expedition Cruises: Some high-end ships heading to Antarctica or doing "deep Patagonia" circuits will stop here for a day if the weather permits. Note the "if." I've known people who paid $15k for a cruise and never got to land because the swells were too high for the Zodiacs.
- Private Sailboats: You can hire a charter out of Ushuaia. This is the "real" way to see it, but you need a skipper with guts and a very sturdy hull. You’ll need a permit from the Argentine Navy (Armada Argentina). They keep a tiny permanent station at Puerto Parry with about four guys who rotate every 45 days. They are the only human inhabitants.
If you make it to Puerto Parry, the navy guys are usually stoked to see a new face. They live in a small fjord surrounded by mountains that drop straight into the sea. It’s stunning, but the isolation is intense. They rely on a naval vessel to bring them supplies once a month. If the weather is bad, the ship is late. Simple as that.
Misconceptions about the weather
People hear "Sub-Antarctic" and think it’s always snowing. Actually, the temperature is relatively stable, usually hovering between 0°C and 10°C (32°F to 50°F). The problem isn't the cold; it's the wet. It is a damp, bone-chilling cold that gets under your skin and stays there.
Humidity is basically 100% all the time.
The wind—the "Westerlies"—is constant. It roars across the Southern Ocean with nothing to stop it until it hits this island. It shapes everything. The trees grow sideways. The birds fly low. Even the water in the fjords looks like it's being whipped into a frenzy.

The biological importance of the Kelp Forests
While everyone looks at the mountains, the real action is underwater. The kelp forests around Isla de los Estados are some of the most pristine on the planet. Macrocystis pyrifera, or giant kelp, creates these massive underwater cathedrals.
These forests are vital for carbon sequestration.
They also protect the coastline from the massive energy of the Antarctic waves. Because there is zero industrial runoff and almost no human presence, the water is incredibly clear, though dark because of the tannins from the peat. Scientists from organizations like National Geographic's Pristine Seas have studied these waters because they represent what the rest of the ocean looked like before we messed it up.
Practical Insights for the Aspiring Explorer
If you are genuinely serious about seeing this place, you have to be prepared for total self-sufficiency. There are no shops. No cell service. No emergency rooms.
- Gear is everything: You need professional-grade Gore-Tex. Not "walking the dog in the rain" Gore-Tex, but "standing under a cold shower for six hours" Gore-Tex.
- The Permit Process: Start your paperwork months in advance if you're going via a private vessel. The Argentine Navy doesn't move fast.
- Seasickness: Even if you think you have iron guts, the Le Maire Strait will test you. Bring the strong stuff—Scopolamine patches or high-dose Meclizine.
- Timing: Go between December and February. Outside of that window, the daylight hours vanish and the storms become frequent enough to keep you trapped in a cove for weeks.
Isla de los Estados isn't a trophy to be won. It’s a place that humbles you. It reminds you that there are still parts of this world where humans aren't the ones in charge.
Actionable Next Steps
If the raw, wild nature of the South Atlantic calls to you, start by researching expedition operators that specifically list "San Juan de Salvamento" or "Staten Island" (the old English name) on their itinerary. Check for vessels with "IAATO" membership to ensure they follow environmental protocols.
Alternatively, if you're a sailor, look into the South Atlantic Circuit guides. Contact the Prefectura Naval Argentina in Ushuaia to understand the current requirements for the "Despacho" (clearance) to the island. You will need a satellite phone, an EPIRB, and enough fuel to fight 6-knot head-currents.
Don't just go for the photo of the lighthouse. Go to experience the silence. It’s one of the few places left where you can actually hear the planet breathe.
