This narrow stretch of sea, surrounded by snow-capped mountains and Patagonian forests, connects the Atlantic Ocean with the Pacific. Sailing through its waters means discovering colonies of sea lions, penguins, southern birds, and the iconic Les Eclaireurs Lighthouse, in a natural environment of untamed beauty that marks the true “End of the World.”

Bird Island, also known as Casco Island, is one of the most iconic natural sanctuaries in the Beagle Channel. Majestic imperial cormorants nest on its rocks and cliffs, their colonies bringing the landscape to life with their unmistakable black and white plumage. While sailing, it is also possible to spot giant petrels, black-browed albatrosses, skuas, and seagulls, making this corner of the end of the world a true paradise for bird lovers and photographers.

Located on a small rocky archipelago in the Beagle Channel, just 5 nautical miles from Ushuaia, Les Éclaireurs Lighthouse is one of the most photographed landmarks in Tierra del Fuego. Its name means ‘The Explorers’ in French, and it was inaugurated in 1920. It is still in operation today, fully automated.

Martillo Island, popularly known as the “Penguin Island,” is a vital natural enclave located in the majestic Beagle Channel in Tierra del Fuego. This small southern territory is world-famous for being home to one of the most important colonies of Magellanic penguins in the region. Every year, between October and April, thousands of these migratory birds choose Martillo Island for their breeding and nesting cycle. The island is not only home to the Magellanic penguin, but also serves as a viewing point for the elegant Gentoo penguin, making it a key destination for conservation and wildlife experiences in the southernmost tip of the continent.
