The Dientes de Navarino trek is one of the southernmost treks in the world, departing from the town of Puerto Williams on Navarino Island in Chilean Tierra del Fuego. It's renowned for its rugged beauty, remoteness, and the spectacular, tooth-like peaks that give the trail its name - "Dientes" means "teeth" in Spanish.

The hike is a circular route that takes you through untouched Magellanic forests, over mountain passes, past beautiful lakes, and gives you stunning panoramic views of the Beagle Channel and Cape Horn.

The trek involves multiple steep ascents and descents, and the trail often involves hiking over rocky, uneven terrain. Additionally, the region's weather can be extreme and change rapidly, with strong winds, rain, and even snow possible, even in the summer months.
