Guardia Marina Zañartu Airport (WPU) serves Puerto Williams, recognized as the southernmost town in the world, located on Navarino Island in Chile's Magallanes Region. The airport acts as a key gateway for adventurers heading to the remote waters of the Beagle Channel, Cape Horn, and even Antarctic expeditions. Named in honor of a Chilean naval officer, it remains a small but strategically important facility bridging the sparsely populated Tierra del Fuego archipelago with the rest of mainland Chile.
💡 Local Tip
Pack a good windproof layer in your carry-on regardless of the season—Puerto Williams is notorious for fierce sub-Antarctic winds that can shift quickly from calm to gale-force, even within minutes of arriving at the small open-air terminal.
🚖 Getting There
Taxis and pre-arranged transfers are the most reliable way to reach the airport from Puerto Williams, as public transport options are limited. Travelers should confirm flight schedules in advance, as weather conditions in the Beagle Channel region can cause delays or cancellations. During winter months, visitors should be prepared for reduced daylight hours and rapidly changing weather that may affect ground transportation availability.
