Silversea officially opened The Cormorant at 55 South on November 5, 2026, a 150-room hotel in Puerto Williams, Chile, the southernmost city on Earth. It is the first hotel Silversea and its parent company, Royal Caribbean Group, have ever built, and it is now the starting point for every Silversea Antarctica Fly Cruise expedition. I have not stayed there yet. This is what the opening actually changes, what the hotel is, and how the new journey to Antarctica works.
What is The Cormorant at 55 South?
The Cormorant at 55 South is a 150-room luxury hotel in Puerto Williams, Chile, at 55 degrees south latitude, built by Silversea as the land-based gateway for its Antarctica Fly Cruise program. It opened on November 5, 2026, with a ribbon-cutting ceremony attended by Silversea executives, Chilean national and regional authorities, and members of the local community. Silversea calls it the southernmost hotel on Earth, and Puerto Williams is the southernmost city on Earth.
The hotel is not a standalone booking in the usual sense. Every guest on a Silversea Antarctica Fly Cruise expedition now arrives in Puerto Williams on a Silversea-branded charter flight, stays at The Cormorant, and then continues to Antarctica. The stay is part of the expedition package, not a room you book on its own. Silversea has not published a standalone nightly rate for the hotel, and the property is not sold as an independent hotel stay. If you want to sleep there, you book a Fly Cruise.
That matters because it answers the most common question about the property directly: no, you cannot simply book a weekend at the southernmost hotel on Earth. You get there by booking an Antarctica expedition that starts in Puerto Williams.
Where is Puerto Williams, and why does it matter?
Puerto Williams sits on Navarino Island in Chilean Patagonia, on the southern shore of the Beagle Channel. It is the southernmost city on Earth, further south than Ushuaia, Argentina, the town most Antarctica operators use as their departure point. Puerto Williams sits further south along the Beagle Channel than Ushuaia, which gives Silversea a shorter, more direct launch point into the Drake Passage.
The Drake Passage is the notoriously rough, 600-mile-wide waterway separating the tip of South America from Antarctica. Silversea’s Fly Cruise program exists to skip it. Instead of spending two days crossing the Drake by ship, guests fly from Santiago to Puerto Williams, stay at The Cormorant, and then take a charter flight across the Drake to King George Island in Antarctica’s South Shetland Islands, where their expedition ship is waiting.
Silversea is the only cruise line running Antarctica operations out of Puerto Williams. Until now, its Fly Cruise passengers stayed in non-Silversea hotels in Punta Arenas, Chile, ahead of the charter flight to King George Island. That arrangement scattered guests across various hotels and left the line scrambling for extra rooms whenever bad weather delayed or grounded flights to Antarctica. The Cormorant fixes that problem by putting every Fly Cruise guest under one roof, minutes from the charter flight, with room to wait out bad weather in comfort.
How the Antarctica Fly Cruise works now
The journey now runs in five stages, and the hotel is the hinge in the middle of it.
First, guests fly non-stop from Silversea’s private terminal in Santiago to Puerto Williams on a Silversea-branded charter flight. Second, they stay at The Cormorant before the voyage. Third, they take a charter flight from Puerto Williams across the Drake Passage to King George Island, where they board their expedition ship. Fourth, they sail the Antarctic Peninsula, and on longer itineraries South Georgia and the Falkland Islands. Fifth, they return to Puerto Williams, spend another night at the hotel, and fly back to Santiago.
That is one night at The Cormorant before the expedition and one night after it, two hotel nights built into every Fly Cruise. The pre-voyage night is not dead time. While at the hotel, guests try on or swap their Silversea-provided Antarctica polar gear, complete the biosecurity checks required before visiting the continent, clean any personal equipment they plan to take ashore, and attend an initial Antarctica briefing. Those are jobs that used to happen on the ship. Now they happen on land, before boarding, which means the expedition itself starts sooner.
The opening coincides with Silversea’s largest Antarctic season to date. Through March 2027, three expedition ships, Silver Endeavour, Silver Wind, and Silver Cloud, will operate 40 voyages, including 29 Antarctica Fly Cruise voyages, each featuring a stay at The Cormorant at 55 South. The season’s itineraries range from 6 to 21 nights and extend beyond the Antarctic Peninsula to South Georgia and the Falkland Islands.

Inside the hotel: rooms, dining, and design
The Cormorant was initially conceived in 2018 as a turnaround hub for Antarctica. Eight years later, it has become something its own president describes as more beautiful than anyone envisioned. The low-slung hotel is designed to blend into its environment, with soaring ceilings, concrete floors, natural wood, stone, and earthy textiles punctuated by pops of orange, yellow, and green that echo the surrounding terrain. Floor-to-ceiling glass keeps the view in frame, whether it is forest, sea, or the snow-scratched Dientes de Navarino peaks and the Andes across the border in Argentina.
The design moves guests from water and darkness toward warmth, wood, and fire, according to Silversea. That is literal as well as thematic: the hotel has a massive indoor firepit surrounded by lounges and easy chairs, and an outdoor terrace for taking in the Patagonian landscape. The Fireplace, the hotel’s gathering space, offers plush seating and expansive windows overlooking the landscape, inspired by the regional tradition of fire as a place for hospitality and storytelling.
Rooms are simply designed, each with a view of mountain or sea, in local wood, natural textiles, and green upholstery. Every room has a Nespresso machine and a small bar fridge stocked with water and craft beer from a brewery in Punta Arenas. The hotel was built using modular construction: each of the 150 rooms was built in Mendoza, Argentina, and transported across the Andes and Patagonia to its place at 55 degrees south.
Dining is built around the region. Latitude 55, the hotel’s restaurant, is rooted in Chilean flavors, regional ingredients, and local culinary traditions, including the asado. Menus start with what grows, grazes, and swims in the region, and dinner is served family-style, with large platters at the center of the table. The asado barbecue, slow-cooked over an open fire in the hotel grounds, is served on the first night of any stay.
Bar Sur is the hotel’s social center. It serves teas and small bites by day and Chilean wines and spirits in the evening, with a wine list that tours Chile from north to south. Calafate, a deep indigo native berry, anchors the cocktails alongside Chilean Pisco, the national spirit, in flavors that are tart, herbal, and warm, with a hint of smoke that echoes the asado fire. The bar team leads a guided Pisco journey, and the hotel’s sommelier leads wine tastings.
Art is part of the building, not decoration added to it. Three large-scale works by Chilean artists anchor the interiors: Navarino, a steel sculpture by Paola Vezzani suspended in the main lobby; Dientes de Navarino, a bar mural by Cata Flaño; and La Memoria de las Piedras, an installation of 70 handcrafted ceramic stones by Javier Canales. The Uncharted Boutique sells Chilean handicrafts and last-minute polar gear.
What to do around the hotel
The Cormorant is a base for Patagonia, not just a waiting room for Antarctica. Guests can kayak the sheltered waters of the Beagle Channel, hike the shoreline trails of Seno Lauta, and explore the landscape on horseback, with chances to spot cormorants, dolphin gulls, and upland geese along the way. A shuttle bus takes guests into Puerto Williams itself.
The hotel is currently open from October through March, the Antarctic season, a six-month operating window. Silversea has said it is considering opening year-round, for travelers visiting southern Chile who want a soft landing after their adventures. That would turn the property from a seasonal expedition gateway into a destination in its own right, and it is the detail to watch if you are interested in Patagonia without an Antarctica cruise attached.

The Cormorant by the numbers: what the opening week coverage actually shows
This is the original data in this article: the math I compiled from the opening-week sources, and the coverage audit of how the story was reported between November 5 and November 7, 2026.
The quotable summary: 29 of Silversea’s 40 Antarctica voyages this season, 72.5 percent, are Fly Cruise departures that include a stay at The Cormorant, and every one of those guests now spends 2 nights at the hotel, 1 before and 1 after the expedition.
Here is the breakdown:
- 72.5 percent of the season is Fly Cruise. 29 Antarctica Fly Cruise voyages out of 40 total voyages through March 2027. That is 29 divided by 40, or 72.5 percent. Fly-cruise itineraries now dominate Silversea’s Antarctica program, and the hotel is the reason the line can run that many of them.
- 2 hotel nights per Fly Cruise guest. One night before the expedition and one night after, according to The Points Guy’s on-site report. Across 29 Fly Cruise voyages, that is 58 voyage-nights of hotel demand built into a single season, before any year-round operation.
- 150 rooms, built 1,000-plus miles from where they stand. Every one of the 150 rooms was built in Mendoza, Argentina, and transported across the Andes and Patagonia to Puerto Williams. Modular construction was the only practical way to build a hotel of this size in the southernmost city on Earth.
- 8 years from idea to opening. Conceived in 2018 as a turnaround hub, opened November 5, 2026. The project took 8 years, and the result is a destination in its own right rather than the functional hub first imagined.
- 18 years of expedition history behind it. Silversea pioneered luxury expedition cruising in 2008. The Cormorant extends that leadership from ship to shore, 18 years after the line’s first expedition sailings.
- 6 to 21 nights. The season’s itineraries range from 6-night Peninsula trips to 21-night voyages reaching South Georgia and the Falkland Islands, a 15-night spread between the shortest and longest options.
- 600 miles of water skipped. The Drake Passage is 600 miles wide. The Fly Cruise replaces a two-day ship crossing with a charter flight from Puerto Williams to King George Island.
- 3 ships, 3 artworks, 70 stones. Silver Endeavour, Silver Wind, and Silver Cloud run the season. Three large-scale Chilean artworks anchor the hotel, including La Memoria de las Piedras, an installation of 70 handcrafted ceramic stones.
- 6-month season, for now. October through March is the current operating window. Year-round operation is under consideration but not confirmed.
Coverage audit, November 5 to 7, 2026: I counted 6 independent outlets reporting the opening in the first 48 hours. Silversea’s own release went out on PR Newswire on November 6 at 16:32 UTC. The Points Guy published an on-site report the same day at 20:42 UTC, after attending the unveiling as one of a handful of travel media outlets given an early look. Travel Codex published November 6 at 17:33 UTC. CruiseLine reported the opening on November 6. RHF News published November 6. The Luxury Lifestyle Magazine published its inside look on November 7. That is 6 outlets in 2 days, including 1 on-site report, which is a strong opening-week signal for a property that cannot be booked on its own.
Why this opening matters for Antarctica travel
The Cormorant changes the Antarctica Fly Cruise in three concrete ways.
First, it removes the weakest link in the fly-cruise journey. Punta Arenas hotels were never designed around expedition departures, and bad weather in the far south is a matter of when, not if. A purpose-built hotel minutes from the charter flight, with 150 rooms held for one operator’s guests, means weather delays become a comfortable extra night instead of a scramble for rooms across town.
Second, it moves expedition preparation off the ship. Polar gear fitting, biosecurity checks, equipment cleaning, and the first briefing all happen at the hotel now. That gives guests more of their ship time in Antarctica itself, and it gives first-time expedition travelers a gentler start than boarding a ship and beginning briefings the same day.
Third, it makes Puerto Williams the center of Silversea’s Antarctica operation. Previously only sailings that crossed the Drake Passage left from Puerto Williams. Now the line will base all its Antarctica expeditions out of Puerto Williams. That is a strategic shift, not a hotel opening alone, and it is why the property matters beyond its 150 rooms.
There is a wider signal here too. Royal Caribbean Group, Silversea’s parent, now owns its first land-based hotel, built in partnership with a consortium of Chilean investors. The group operates 71 ships sailing to more than 1,000 destinations across all seven continents, and it is expanding into land-based vacation experiences, including its Perfect Day and Royal Beach Club private destinations, with Celebrity River Cruises entering river cruising in 2027. The Cormorant is the group’s first hotel, and it is a test of whether a cruise company can run a land-based property to the same standard as its ships.

How to book, and what it costs
There is no standalone rate to quote, and I am not going to invent one. Silversea has not published a nightly rate for The Cormorant at 55 South, and the hotel is not sold as an independent stay. The way to sleep there is to book a Silversea Antarctica Fly Cruise expedition, which includes the pre- and post-voyage nights at the hotel in the fare.
Fly Cruise itineraries run 6 to 21 nights, and the season runs through March 2027. Fares vary by ship, cabin, and itinerary length, and Silversea prices its Antarctica expeditions as all-inclusive fares covering the charter flights, the hotel nights, and the expedition itself. Check the fare for your specific sailing on Silversea’s site, and confirm what is included before you book, because the hotel nights, the Santiago charter, and the King George Island flight are part of the package, not add-ons.
If you are planning around the hotel specifically, the practical questions to ask when you book are: which of the three ships you will sail on, how many nights your itinerary runs, whether your sailing is one of the 29 Fly Cruise departures, and what happens to your hotel stay if weather delays the charter flight. The Cormorant was built to absorb exactly that delay, and that is its real value.
