14,435 feet above sea level, Langza is a small village on the road from Kaza to Komik. A population of just 137 inhabits the area, watched over by a statue of Buddha. The village belongs to the Sakyapa sect of Tibetan Buddhism and has a 1000 year old temple. Langza is best known in the valley for its richness in fossils dated back to when Spiti was submerged in the Tethys sea. Other attractions here are a trek to
