The largest penguin colonies in southern Chile, Los Pingüinos Natural Monument is home to more than 120,000 Magellanic penguins. Located on the small Magdalena Island, just one square kilometer and topped by a pretty red lighthouse, it lies 35 km northeast of Punta Arenas. In September or October each year, the birds migrate back here and find their mate. By the end of March the penguins have returned to sea again.
