A new hotel claim is coming to the bottom of the map. In Puerto Williams — the Chilean navy town on Isla Navarino that holds the title of world's southernmost city — Silversea is opening The Cormorant at 55 South in October 2026, and it will be the southernmost hotel on the planet. With 150 rooms, it dwarfs the handful of small lodges currently in town.

Here's the catch: you can't just book a night. The hotel is reserved for passengers on Silversea's Antarctica Fly Cruises sailing aboard the ice-class expedition ships Silver Endeavour, Silver Wind and Silver Cloud. The stay is folded into the cruise fare, covering your nights before and after the voyage.

Building it was an operation in itself. The hotel was prefabricated in modules in Mendoza, Argentina — furnished down to the wall art — then shipped south on a journey taking more than a week. A locally based architect designed it to sit quietly among the trees above the Beagle Channel, with floor-to-ceiling windows looking out to sea or forest.

On the food and drink front, restaurant Latitude 55 will lean on local Patagonian ingredients, while Bar Sur pours Chilean wine and runs cocktail classes featuring pisco. Between cruises, guests can join guided hikes, horseback riding and kayaking, or go birdwatching for the cormorants that gave the hotel its name — with whales and dolphins possible in the channel. There's also a Fireplace Lounge for doing nothing much, and an on-site boutique, Uncharted, selling work by Chilean artists.

One practical perk: Antarctica packing is notoriously awkward, so Silversea supplies the expedition kit — parka, waterproof boots and pants — and guests will be fitted for it at the hotel rather than squeezed onto the ship.

The bigger selling point is what the fly-cruise format skips: the Drake Passage. That 600-mile stretch between South America and the Antarctic Peninsula is one of the roughest crossings in the world, and flying over it turns a two-day rollercoaster into a flight of about one hour and 45 minutes from South America to King George Island, where guests board the ship. That means more time on the ice and less time gripping a bunk rail. Eventually the flight base is expected to move to Puerto Williams itself, which will make the whole operation even smoother.

For anyone who has priced an Antarctica trip, the maths matter here: the hotel nights are included in the cruise cost rather than bolted on, and the pre- and post-cruise logistics are handled in one place. It's aimed squarely at travellers who want a high-end, low-friction route to the White Continent — and who'd rather not gamble on Drake Passage weather. If Puerto Williams has been on your list as a tick-box of the far south, this gives it a reason to be more than a stopover.
