Niʻihau: The Island You See From the Water

On your own, you cannot: outsiders may not land on Niʻihau or visit its one village, Puʻuwai, and the boat trips stay in the water. You cannot stay overnight or get around the island by yourself. The only visitors who set foot on the island come on the owners' half-day helicopter tours or their guided hunts, which land on uninhabited beaches, and published accounts say these involve no contact with residents. Lehua, the islet off the north shore where the snorkel boats stop, is a restricted seabird sanctuary where nobody may go above the high-water mark.

Because it is private land, closed to most outsiders by its owners since 1915. Elizabeth Sinclair bought the island from King Kamehameha V in 1864, and her descendants, the Robinson family, own it today. The nickname “the Forbidden Island” dates from the 1952 polio epidemic, when, as one owner told ABC News, it was forbidden to come out “unless you had a doctor's certificate, and there was a two-week quarantine”. The Hawaiʻi Tourism Authority's style guide says Niʻihau should not be promoted as a destination, because it is strictly by invitation of the private owners.

Yes: 84 people in 18 households at the 2020 Census. That is down from 170 in 2010, 160 in 2000 and 230 in 1990; the owners' website still says about 200, which is out of date. The island's only village is Puʻuwai. The community speaks Hawaiian as its primary language, and 84.5% of the 2020 residents were Native Hawaiian alone or in combination.

The part visible to outsiders is two businesses the owners run from Kauaʻi: helicopter tours and guided hunts. Niʻihau Safaris holds exclusive hunting rights, for free-roaming Polynesian boar and feral sheep among other animals, with parties capped at five; Niʻihau Helicopters flies half-day trips that land on the island's beaches. The sources this page relies on say nothing more about the island's finances.

None of the sources this page uses describes a way to be invited; the Hawaiʻi Tourism Authority calls the island strictly by invitation of its private owners. ABC News reported that for generations the only people allowed on Niʻihau were Robinson relatives and the Niʻihauans of Puʻuwai. What is open to visitors is limited: the owners' helicopter tours and hunts, which land on uninhabited beaches, and boat trips from Kauaʻi that snorkel near Lehua without landing.

Usually Niʻihau and Kahoʻolawe, the two main islands visitors cannot simply visit. Niʻihau is privately owned and closed to most outsiders; its nickname, the Forbidden Island, dates from a polio quarantine in 1952. Kahoʻolawe is closed for different reasons, which the Kahoʻolawe guide explains.

Not before 11 October 2026: Holo Holo Charters cancelled all its tours through 10 October, and the calendar on this page shows dates from 11 October. Lowell damaged Port Allen harbor; the launch ramp reopened on 2 October while the slips and moorings stayed closed, and Holo Holo said its restart depended on State direction about the ramp. Free cancellation runs to 7 days before, so check the calendar again before that point. Even in normal times the captain sets the route on the day, and reviewers describe the Niʻihau stop being dropped for weather.

No. It snorkels in the water near Lehua, the crescent islet off Niʻihau's north shore, and nobody goes ashore. Lehua covers 284 acres; it is a State seabird sanctuary managed by DLNR and owned by the U.S. Coast Guard, access is restricted to areas below the high-water mark, and commercial activity on it is prohibited. Another operator, Blue Dolphin Charters, says on its own page that there is no landing on Niʻihau's coast.

A seven-hour cruise with breakfast, lunch, snorkel gear and instruction. Holo Holo serves a continental breakfast, a deli-style buffet lunch and soft drinks all day, with beer and wine only after snorkeling, and provides ocean-friendly sunscreen; tips are extra. It cost $339 when we checked (4.7 from 160 reviews). Check in at the Port Allen Marina Center, 4353 Waialo Road in ʻEleʻele, and park in the gravel lot past the center. Bring ID for age checks, swimwear, a towel and a jacket. Children under 5, pregnant guests and anyone with back problems or recent surgery, or prone to seasickness, should not book; there are no refunds for seasickness, mobility aids are not allowed on board, full-face snorkel masks are banned, and snorkeling within 24 hours of arriving on a flight longer than 5 hours is not advised.

The owners run one, Niʻihau Helicopters, but whether it is flying after Hurricane Lowell is unconfirmed. Its half-day trips leave Kaumakani on Kauaʻi's west side in a twin-engine Agusta 109A, fly over the island and land on a beach chosen by the wind for swimming, snorkeling and beachcombing, with lunch included. Its website shows no date or current status, and Lowell's eyewall brushed Niʻihau on 8 September. It is not sold online, so check with the operator directly.

The Robinson family, descendants of Elizabeth Sinclair, who bought the island from King Kamehameha V in 1864. Secondary sources put the price at $10,000 in gold. A Kamehameha Schools data book counts the family's holdings at about 46,000 acres on Niʻihau and about 56,000 on Kauaʻi. Brothers Bruce and Keith Robinson are widely named as the current owners.
