Laguna San Rafael National Park
Aisén del General Carlos Ibañez del Campo
Laguna San Rafael National Park is a sprawling natural reserve located on Chile's southern Pacific coast in the Aisén region. Established in 1959, it encompasses over 17,000 square kilometers, including the Northern Patagonian Ice Field and towering Andean peaks such as Monte San Valentín. The park's centerpiece is the San Rafael Lagoon, formed by the retreat of the San Rafael Glacier, a tidewater glacier known for spectacular ice calving events. Visitors can explore the fjord stretching over 16 kilometers and witness massive icebergs floating in the lagoon. The park is recognized as a UNESCO World Biosphere Reserve, sheltering diverse wildlife including black-browed albatrosses, South Andean deer, marine otters, and endangered southern right whales that migrate through nearby waters. The climate is notably wet, with annual precipitation reaching up to 5,000 mm, supporting lush temperate rainforests and snowfields at higher elevations. Access to the park is primarily by boat from Puerto Montt or Puerto Chacabuco, or via a gravel road leading to Bahía Exploradores, from where boat tours to the lagoon depart. The park remains relatively remote and lightly visited, offering a pristine wilderness experience.

Historia
The area of Laguna San Rafael was first explored by non-indigenous people in 1675, at which time the San Rafael Glacier was land-terminating.
Between 1741 and 1766, the glacier advanced to reach the lagoon and has remained a tidewater glacier since.
The park was officially established in 1959 to protect its unique glacial and ecological features.
In 1979, UNESCO designated it a World Biosphere Reserve, recognizing its global ecological importance.
The park's boundaries also protect significant Andean peaks and the Northern Patagonian Ice Field, one of the largest ice masses outside the polar regions.
