A thin, bitter wind slides down the flanks of Iztaccihuatl as headlamps blink like a stitched constellation. On the first evening, small groups off the road at Paso de Cortés shoulder packs and climb to the Altzomoni refuge while the silhouette of Popocatépetl glares across the saddle. By night the refuge is a practical knot of breathing, boots, and steaming mugs—by 2:00 a.m. the mountain asks for steady legs and quiet focus.
