Lago Maihue is a stunning glacially-carved lake nestled in the Los Ríos region of southern Chile, sitting at an elevation of 169 meters (554 feet) above sea level. Stretching approximately 48 kilometers in length and up to 10 kilometers wide, it covers a surface area of 226 km² (87 square miles) within a vast watershed basin of over 15,000 km². The lake drains through the Calcurrupe River, which flows westward and eventually connects to the Río Bueno system. Surrounded by native Valdivian temperate rainforest and set against a backdrop of volcanic Andean peaks, Lago Maihue is widely regarded as one of the premier fishing destinations in southern Chile, offering world-class trout and salmon angling in a remarkably wild and scenic setting.
