A cold wind pushes across the moraine as the first pale light reveals the rim of Tilicho Lake, its surface a sheet of blue set against jagged glacier teeth. On this 21‑day itinerary travelers move from the crowded alleys of Kathmandu into the high, stony quiet of the Annapurna massif—through rhododendron forests, terraced villages, and thin‑air plateaus where the Himalaya seem to lean in.

Acclimatize in Manang
