San Rafael Lagoon

San Rafael Lagoon is a proglacial and measures approximately 15 kilometers long (north to south) and 10 kilometers wide (east to west) and has up to 200 meters of depth.

San Rafael Lagoon is a proglacial lake linked to the sea by the River Témpanos. It measures approximately 15 kilometres long (north to south) and 10 kilometres wide (east to west), and has up to 200 meters of depth. Despite the great inflow of freshwater from the glacier and the numerous streams, its waters are salty due to the effect of the tide.

It is one of the most important tourist attractions of the Aysén region and of Patagonia; the huge San Rafael Glacier has a front that measures 2 kilometres wide (north to south) and a length of approximately 20 kilometres. The glacier wall is over 50 metres high and, from there, huge pieces of ice detach and fall right into the lagoon. It is the glacier that reaches sea level closest to the equator, in the southern hemisphere.

The glacier has become a study object for climate change monitoring, given that its slopes reveal the presence of ice erosion through thousands of years.

San Rafael Lagoon and its glacier are located in Campos de Hielo Norte, which in turn is located entirely within Laguna San Rafael National Park, where CONAF is in charge of keeping a small office and infrastructure within the park, near the camping area.

In this national park, it is also possible to sight some of the terrestrial and marine wildlife of the region, among the outstanding birds, we find: the huala duck (Podiceps major navasi,) the black-necked swan (Cygnus melancoryphus) and the cormorant (Phalacrocorax atriceps.) In the sea, one can usually sight: the dolphin (Cephalorhynchus eutropia,) the South American sea lion (Otaria flavescens,) the chunchungo or marine otter (Lontra felina) and the southern elephant seal or elefante marino, in Spanish, (Mirounga leonina).

In 1979, this park was declared a World Biosphere Reserve by UNESCO.
