Puerto Williams, located on Navarino Island in Chilean Patagonia, proudly holds the title of the southernmost city on Earth. Often overshadowed by larger and more commercial towns such as Ushuaia, Puerto Williams offers something different—raw wilderness, ancient indigenous culture, pristine landscapes, and a peaceful, remote lifestyle that attracts adventurers from around the world. This extensive guide explores everything you need to know about Puerto Williams, from its history to its top attractions, trekking routes, travel tips, climate patterns, and local culture.
Founded in 1953 as a Chilean naval base, Puerto Williams has evolved into a scientific, cultural, and eco-tourism hub. The city sits in a region historically inhabited by the Yahgan (Yámana) people, one of the world’s southernmost indigenous groups. Their resilience in surviving the harsh subpolar climate for thousands of years forms a critical chapter in human adaptation and anthropology.
Today, Puerto Williams is home to several research institutions focused on marine biology, climate change, and subantarctic ecosystems. Its location along the Beagle Channel makes it strategically significant not only for Chilean maritime operations but also for international scientific collaboration.
Puerto Williams rests on the northern coast of Navarino Island, across from the Argentine city of Ushuaia. The city is surrounded by dramatic landscapes featuring glaciers, towering peaks, peat bogs, dense Magellanic forests, and fjords carved by ancient ice. Its remote location makes it one of the least disturbed environments on the planet.

Though small in size, Puerto Williams boasts extraordinary attractions that immerse visitors in pure Patagonian wilderness.
The Dientes de Navarino circuit is often called the world’s southernmost trek. This 53–60 km loop offers views of jagged peaks resembling “teeth” (dientes), untouched valleys, glacial lakes, and alpine passes. It is more rugged and remote than the Torres del Paine W trek, making it perfect for seasoned hikers seeking solitude.
This park is a living laboratory where visitors learn about the unique mosses, lichens, and mini-forests of the subantarctic ecosystem. The “Tourism with a Hand Lens” initiative encourages microscopic appreciation of nature, highlighting the richness of small-scale biodiversity.
The museum documents the culture and adaptation of the Yahgan people. Exhibits include tools, photographs, and Gusinde’s field notes. It offers a fascinating look at how humans survived extreme environments long before modern technology.
Boat tours from Puerto Williams offer views of glaciers, sea lions, humpback whales, Magellanic penguins, and remote fjords that few travelers ever see. This is one of the most peaceful and least commercial wildlife viewing experiences in the world.
As tourism grows, Puerto Williams faces the challenge of balancing economic development with environmental preservation. A recent study by Chilean subantarctic research institutes shows that:
This case demonstrates how the world’s southernmost city is becoming a leader in sustainable travel, setting an example for remote communities globally.
Reaching Puerto Williams requires planning, but the journey is part of the adventure.
Air travel is the most common and reliable option, especially during winter when sea conditions become unpredictable.
