Garibaldi Glacier, Chile

Garibaldi Glacier is considered one of the most beautiful in all of Chile. Set at the head of its eponymous fjord within Alberto de Agostini National Park, this massive, retreating tidewater glacier emerges from the extensive ice field that lies within the park. It measures half a mile wide at its face and sits back more than 10 miles from where Garibaldi Fjord ends in the Beagle Channel. Unlike the moraine or glacial till carried along by most glaciers, Garibaldi has a medial moraine, which indicates the merging of two individual glaciers. It is one of several found within the fjord, which also features a series of cascading waterfalls and several small icebergs deposited by glacier calving. Alberto de Agostini National Park, Chile’s third largest, protects some 3.6 million acres and makes up the core of Cabo de Hornos Biosphere Reserve. It encompasses the extensive Cordillera Darwin mountain range, as well the southernmost forests in the world. As your Zodiac cruises near the face of Garibaldi Glacier, keep an eye out for playful seals and sea lions; Magellanic penguins and even orcas are spotted here, while Andean condors are seen overhead.
