The trail opens with a thin, cold light over Kathmandu as your plane drops into Lukla and the mountains close in like a wall. You move from pine-scented valleys into high, wind-scoured ridgelines, crossing suspension bridges and mani walls while the Dudh Koshi river dares you to hurry. Villages grow quieter and the air thinner until ice and the Khumbu Glacier dominate the view at Gorak Shep.
