For over thirty years, almost all commercial Antarctic expedition cruises departed from Ushuaia, Argentina. However, as the popularity of polar exploration skyrocketed, Ushuaia's narrow port infrastructure became heavily congested, with dozens of large cruise liners and expedition vessels competing for dock space, fuel lines, luggage clearance, and tender landings.
In a masterstroke of luxury logistics, Silversea boldly charted its own course: establishing Puerto Williams, Chile as the exclusive southern hub for its Antarctic fleet, and constructing The Cormorant at 55 South, a dedicated 150-room luxury hotel reserved entirely for Silversea guests.
Why Puerto Williams Surpasses Ushuaia
Located on Navarino Island on the southern bank of the Beagle Channel, Puerto Williams is officially recognized by international geographical bodies as the southernmost incorporated town on Earth, sitting south of Ushuaia. For Silversea guests, this location provides five decisive advantages:
5 Unmatched Advantages of Puerto Williams
- Zero Port Congestion: While Ushuaia's harbor can host up to eight massive vessels simultaneously with thousands of passengers crowding customs checkpoints, Puerto Williams is an exclusive, private departure point. Only Silversea expedition vessels operate here, ensuring immediate, serene boarding.
- Closer Proximity to Antarctica: Positioned further south than Ushuaia, ships departing Puerto Williams enter the Drake Passage faster, shaving valuable nautical miles and sailing hours off the crossing.
- Private Chartered Santiago Flights: Silversea guests fly on dedicated private charter flights directly from Santiago to Guardiamarina Zañartu Airport (WPU) in Puerto Williams, eliminating crowded commercial airline transfers in Buenos Aires.
- Seamless Chilean Customs Clearance: Because both Santiago and Puerto Williams are within Chile, guests experience a single domestic transit without complex cross-border visa or immigration delays before embarkation.
- Pristine Sub-Antarctic Wilderness: Puerto Williams is nestled within the UNESCO Cape Horn Biosphere Reserve, surrounded by ancient Magellanic sub-polar forests and the jagged peaks of the Dientes de Navarino mountains.

Inside The Cormorant at 55 South: Silversea’s 150-Room Hotel
Developed through a landmark partnership between Silversea and local Chilean architectural innovators, The Cormorant at 55 South represents the single most significant hospitality investment ever completed in southern Patagonia. Designed specifically to harmonize with the fragile Sub-Antarctic ecosystem, the property delivers an effortless bridge between long-haul flights and the polar ice.
Architectural Elegance & Patagonian Craftsmanship
The architecture draws inspiration from traditional Patagonian ranching estancias and the maritime heritage of the Yaghan people who originally inhabited Navarino Island. Floor-to-ceiling glass walls capture the ever-changing light over the Beagle Channel, while sustainable local timber, native stone masonry, and rich wool textiles create an inviting sanctuary.
World-Class Patagonian Dining
The hotel's expansive restaurant showcases fresh regional delicacies: Magellanic king crab (Centolla), Patagonian lamb roasted over open wood embers, and freshly harvested calafate berries, paired with premier Chilean vintages from the Colchagua and Maipo Valleys.
Panoramic Beagle Channel Lounge
Relax by roaring stone fireplaces with bespoke craft cocktails, Pisco Sours, and warm artisanal beverages while gazing out through 20-foot glass windows at snow-capped peaks across the Beagle Channel.
Relaxation & Acclimatization Center
Recharge after international flights with private sauna facilities, thermal relaxation areas, and curated walking paths meandering through pristine Patagonian moss forests before your polar embarkation.
White-Glove Luggage Integration
Silversea's hospitality staff offloads your luggage directly from the charter aircraft into the hotel. When it is time to board the ship, your bags are placed directly into your suite by your dedicated butler.
