You step out of the vehicle before dawn and the cold hits with the clarity of thin air; a pale line of peaks already burning gold where the sun first touches them. Nevado Mateo rises like a carved ridge against the sky, a compact 5,150-meter summit that gives a full 360-degree vantage of the Cordillera Blanca inside Huascarán National Park. The route begins with an hour of ascending dirt track through high puna grass, then the group rigs up—crampons, ice axes, harnesses—before crossing firm, glaciated slopes to the summit.
