To the south of the Cockburn Channel, you’ll sail by Alberto de Agostini National Park. This is where the Andes, the world’s longest above-ground mountain range, comes to an end in its southernmost extension, the Cordillera Darwin. Chile‘s third-largest park has a landscape of soaring peaks and deep fjords, though a large part of why it was added to UNESCO’s list of Biosphere Reserves is harder to spot from a ship. The biosphere that includes it and nearby Cape Horn National Park is home to 5 percent of the world’s bryophytes, that is, those plants without vascular systems, including mosses and liverworts.
