Laguna San Rafael National Park is a park located on the Pacific coast of southern Chile.The park is named for the San Rafael Lagoon formed by the retreat of the San Rafael Glacier. Created in 1959, it covers an area of 17,420 km2 (6,726 sq mi) and includes the Northern Patagonian Ice Field. A fjord more than 16 km (10 mi) long is one of the park's principal attractions.
Non-indigenous people first explored the area of Laguna San Rafael in the year 1675. The glacier of the same name was a land-terminating glacier during that time. It probably reached again the lagoon at some time between 1741 and 1766, and it has been a tidewater glacier since that date.
