The town of Kaza, Kaze or Kaja is the subdivisional headquarters of the remote Spiti Valley valley in the Lahaul and Spiti district of the state of Himachal Pradesh in the Western Himalayas of India. Spiti, which is a part of the Lahaul and Spiti district of Himachal, is a high altitude or cold desert having close similarities to the neighbouring Tibet and Ladakh regions in terms of terrain, climate and the Buddhist culture. Kaza, situated along the Spiti River river at an elevation of 3,650 metres (11,980 ft) above mean sea level, is the largest township and commercial center of the valley and also the largest district of India.
The town is divided into the old, as Kaza Khas and new as Kaza Soma sections. The new town contains the administrative buildings. The Tangyud (Tang-rGyud) Gompa dates to the early 14th century and is built like a fortified castle with massive slanted mud walls and battlements with vertical red ochre and white vertical stripes. It is on the edge of a deep canyon and overlooking the town of Kaza, 4 km from the town. Approaching it from the south one sees Kyu-ling (Skyid-gling), the stately palace of the Nono (king) on the other side of the river.[3
Kaza is overlooked by high mountain ridges on all sides. It has two access points : one from Kinnaur valley and the other from the Lahaul valley, 11 km from Ki Monastery, the famous Gelugpa establishment. The route through Kinnaur is open throughout the year, except for occasional short periods resulting from landslides or heavy snowfall. This road, starting from Shimla, follows the Sutlej river unto a little beyond Reckong Peo, thereafter turning northwards to follow the Spiti river all the way to Kaza. The other road starts from Manali and after crossing the 13,090-foot (3,990 m) high Rohtang Pass and the 14,928-foot (4,550 m) high Kunzum pass, enters the Spiti valley to reach Kaza. It remains closed during winter months due to heavy snowfall on both the passes
Kaza is known for its colorful festivals and the ancient Sakya Tangyud Monastery in a side valley, 4 km from the town. It is also popular with tourists and adventure seekers during summer months because of its central location and connections to rest of the valley and outside.
