For those seeking a full exploration, the Manali–Kaza circuit is the ultimate Spiti trek. Starting amidst lush greenery, trekkers gradually ascend into barren highlands and icy passes. The journey bridges two worlds — the verdant valleys of Kullu and the stark desert of Spiti. Along the way, visit the remote villages, cross Kunzum Pass, and end by gazing at the stars from Kaza. This trek captures the essence of transition — from life’s chaos to peaceful stillness.
