Puerto Williams
Discover Puerto Williams, the world's southernmost town in Chilean Patagonia. Home to the epic Dientes de Navarino trek, gateway to legendary Cape Horn, and rich Yaghan culture. An unparalleled adventure awaits in this remote corner of the earth.
Nestled on Navarino Island, Puerto Williams holds the distinction of being the southernmost town in the world, a title fiercely debated but widely accepted over Ushuaia when considering official population definitions. This remote Chilean outpost, located across the Beagle Channel from Argentina's Tierra del Fuego, is a true frontier destination for the intrepid traveler. It serves as the primary base for expeditions to the mythical Cape Horn and is the starting point for one of Patagonia's most challenging and rewarding treks: the Dientes de Navarino. Here, raw nature, rich indigenous history, and unparalleled solitude converge.
Traveling to Puerto Williams is an experience in itself, requiring meticulous planning due to its extreme remoteness and limited infrastructure. Expect basic but welcoming accommodations, a strong connection to the sea and the Chilean Navy, and a unique opportunity to immerse yourself in the Yaghan culture, the indigenous people who have called this harsh yet beautiful land home for millennia. For those seeking true wilderness, bragging rights, and an authentic Patagonian adventure far from the usual tourist trails, Puerto Williams is an unforgettable journey to the end of the world.

Driving Tips
- 1Forget renting a car in Puerto Williams: There are no car rental agencies available on Navarino Island. Travel within the town is primarily by foot or local taxi/colectivo.
- 2Extremely limited road network: The paved roads are confined mostly to Puerto Williams itself, with a short extension to Omora Ethnobotanical Park. All other excursions will involve boats or trekking.
- 3No cross-island driving options: While some unpaved tracks lead to remote estancias, they are not suitable for tourist vehicles, and self-driving is not a practical or recommended option for visitors.
- 4Consider a vehicle ferry from Ushuaia: If bringing a vehicle is absolutely necessary (typically for long-term residents), the only realistic option is the infrequent and expensive ferry from Ushuaia. This is not practical for short-term tourism.
- 5Embrace alternative transport: The best way to explore Navarino Island and its surroundings is by boat for accessing the Beagle Channel and Cape Horn, or on foot for the Dientes de Navarino trek and local exploration.
Local Tips
- 1Carry Chilean Pesos (CLP) in cash: While some places accept cards, many smaller businesses, especially outside town, only take cash. ATMs are limited and can sometimes be out of service.
- 2Book everything in advance: Due to its remoteness, flights, ferries, accommodation, and Dientes de Navarino trek permits (required through CONAF) must be secured well ahead of your trip.
- 3Prepare for all weather conditions: Even in summer, Puerto Williams can experience all four seasons in one day. Pack layers, waterproof and windproof gear, and sturdy hiking boots.
- 4Respect Yaghan culture: Engage respectfully with the local Yaghan community. Visiting the museum and supporting local crafts is a great way to learn about their heritage.
- 5Learn basic Spanish phrases: While some locals speak English, having a few Spanish phrases will greatly enhance your interactions and make navigating local services easier.
