The Islands That Don't Want You There (And the One Loophole That Lets You In)

Some islands are closed to you by law, by gods, by venom, or by a tribe with bows who would very much like you to leave. I went looking for the ones you cannot visit — and found the surprising legal loophole that gets you onto the hardest of them.

The captain cut the engine about 400 meters off the island and said, very calmly, “We do not get closer than this.” I asked why. He pointed at the trees, golden in the morning light, gorgeous, and said: “One per square meter. Sometimes more.” He meant the snakes. He meant that the island in front of me, the prettiest thing on the horizon, was so full of venom that the Brazilian Navy had made it a crime to set foot there.

I have spent an embarrassing amount of time chasing islands that actively, legally, sometimes lethally do not want me. Here’s what I learned — and the one loophole that genuinely works.

Forty minutes off the coast of Sao Paulo state sits Ilha da Queimada Grande, which everyone calls Snake Island, because it is an island of snakes. Specifically the golden lancehead, a pit viper found nowhere else on Earth, whose venom is potent enough to — and I’m quoting a herpetologist, not being dramatic — melt human flesh. Estimates of the population vary wildly, but it’s dense enough that the Brazilian government has banned all visits outright.

The only people who legally land are a handful of scientists and the navy crews who service the automated lighthouse, and even they go in with a doctor and antivenom. The famous local legend says the last lighthouse keeper and his family died when snakes came in through the windows. It’s probably embellished. I chose not to investigate from closer range.

You can, however, take a boat out from the mainland to circle it at a legal distance, which is exactly what I did. From the water it’s just a green hill in a blue sea. The horror is entirely invisible, which is somehow worse.

Far harder, and far more important to respect, is North Sentinel in the Andaman Islands, India. It’s home to the Sentinelese, one of the last peoples on Earth living in voluntary isolation, with no peaceful contact with the outside world. They have made their position extraordinarily clear over the years — they fire arrows at boats and aircraft that approach — and India, rightly, enforces a strict exclusion zone around the entire island. Approaching is illegal, and it is enforced.

This is the one on every “forbidden islands” list, and I want to be blunt about it: the rule here isn’t a quirk to be beaten. The Sentinelese have no immunity to common outside diseases, so a single visitor could be a catastrophe. The correct way to “visit” North Sentinel is to not. I include it because the most interesting thing about the world’s forbidden places is that some of them are forbidden out of pure respect, and the only honorable move is to leave them be.

Off the south coast of Iceland is Surtsey, an island that did not exist before 1963. It erupted out of the sea in a volcanic birth that lasted years, and from the moment it cooled, scientists made a once-in-history decision: leave it completely untouched, so they could watch how life colonizes brand-new land from absolute zero — first seeds drifting in, then mosses, then the first nesting birds, then plants those birds brought.

So Surtsey is closed not because it’s dangerous but because human footprints would contaminate the cleanest natural experiment on the planet. A single rogue tomato plant once sprouted from a researcher’s improperly handled lunch and was solemnly uprooted. Only a tiny number of scientists ever land. You can see it from sightseeing flights and boat tours along Iceland’s south coast — a stark black dome rising from the Atlantic, off-limits and pristine.

Now the loophole. Most “forbidden” islands stay forbidden. But Niihau, the “Forbidden Isle” of Hawaii, is the rare one with a real, usable side door.

Niihau is privately owned — bought by the Sinclair-Robinson family in 1864 — and the owners have kept it deliberately closed to outsiders for over 150 years to protect the roughly 100 Native Hawaiian residents and their traditional way of life. No tourists, no through-traffic, no casual visits. For generations, “you cannot go to Niihau” was simply a fact.

The loophole: the owning family runs a small number of strictly limited, expensive activities that legally put you on or just off the island. There are permitted half-day hunting safaris (for feral sheep and boar) and helicopter tours that touch down on remote, uninhabited beaches far from the village — so you can technically set foot on the Forbidden Isle without ever entering the residents’ lives. It is not cheap and it is not a beach holiday. But it is a genuine, legal way onto an island that has told the world “no” since before the American Civil War ended.

That’s the pattern worth understanding. The islands closed by venom (Queimada Grande) or by isolation (North Sentinel) or by science (Surtsey) have no door. The ones closed by ownership sometimes do — because a private owner can also choose, on their own terms, to let a careful few in.

Base in Sao Paulo for the Snake Island boat circuit, in Kauai for the Niihau loophole, and on Iceland’s south coast (around Vik or Heimaey in the Westman Islands) for Surtsey flights and boat views. For North Sentinel, the responsible itinerary is the rest of the Andamans — Havelock and Neil islands are spectacular and welcoming — while leaving the Sentinelese entirely alone.

The thrill of these places isn’t conquest. It’s the strange dignity of a piece of land that has the standing to say no — to a government, a navy, a billionaire, or you. Most of the time the right answer is to respect the no. And just occasionally, on one private island in the Pacific, there’s a door — and you’re allowed to knock.

Which forbidden island can I actually, legally visit?

Niihau in Hawaii is the realistic one — the owning family runs sanctioned helicopter tours and hunting safaris from Kauai that legally land you on uninhabited parts of the island. Snake Island and Surtsey can only be viewed from offshore boats or flights, and North Sentinel must not be approached at all, by law and out of respect for the Sentinelese.
