3) Langhza, Komic and Hikkim. All these three places are close to each other, and do not have any buses plying between them and Kaza. Many people trek, while some hire taxis. Although, I must warn you that trekking at this altitude is quite taxing physically. Langhza is a village that is known for its pottery, and has a large statue of Buddha overlooking the village. Comic id the highest village in Spiti, and claimed to be the highest village in Asia. The post office in Hikkim is the highest in the world, and you can send postcards from here to anywhere in the world for a small price. Quite a fancy kind of souvenir!
