Isla Fresia is an island situated near the northeastern shore of Lago Puyehue in the Los Lagos Region of Chile, surrounded by the Andes and more than five snow-capped volcanoes rising above dense temperate native forest.

The island rises roughly 200 meters above the lake's surface and covers more than 400 hectares of unfenced terrain, a mix of native forest, meadows, and shrubland.

First settled by Austrian immigrants in the late 1930s, Isla Fresia has a predominantly temperate climate.

Lago Puyehue itself spans 157 square kilometers with a length of 23 kilometers and a depth of 135 meters, offering calm waters and mountain scenery that make the area a draw for visitors to the region.
