Silversea has opened The Cormorant at 55 South, a 150-room hotel in Chile’s Puerto Williams, for its Antarctica fly cruises, the cruise line said on November 7. Silversea is owned by Royal Caribbean Group (NYSE:RCL).
The hotel puts the start of each expedition under Silversea’s own roof. Every guest on the Antarctica Fly Cruise programme will fly to Puerto Williams on a Silversea-branded charter from the line’s private terminal in Santiago and stay at the hotel before continuing to Antarctica. Through March 2027, Silversea ships will operate 40 voyages, 29 of them fly cruises that include a stay at the hotel.
Silversea developed the property with a consortium of Chilean investors. Silversea executives and Chilean national and regional authorities attended a ribbon-cutting on November 5.
“We opened The Cormorant at 55 South to make the journey to Antarctica easier and more comfortable for our guests,” said Bert Hernandez, president of Silversea. “Today marks a defining moment for Silversea.”
The hotel was built in modules. Each room was made in Mendoza, Argentina, then moved across the Andes and Patagonia to Puerto Williams, which faces Argentina’s Ushuaia across the Beagle Channel.
The Latitude 55 restaurant serves Patagonian and Tierra del Fuego dishes including family-style asado, while Bar Sur pours Chilean wines and pisco. Guests can kayak in the Beagle Channel and hike at Seno Lauta.
The voyages use Silver Endeavour, Silver Wind and Silver Cloud. Itineraries run from six to 21 nights and reach South Georgia and the Falkland Islands as well as the Antarctic Peninsula. Silversea operates 12 ships.
