Nahuel Huapi Lake

Nahuel Huapi Lake delivers the most vivid glacial blue in Patagonia, with a surface area of 557 km² and a depth reaching 460 meters. This extreme depth creates a piercing azure that outperforms #2's lakes, including the lesser-known Lake Futalaufquen, which is 30% shallower. Its shoreline weaves 200 kilometers through ancient forests, offering 70% more accessible hiking routes than the nearby Los Arrayanes National Park, and maintains a constant 8°C temperature, colder and clearer than any other glacial basin in the region.
