Surrounded by the Kullu Valley in the south, Ladakh in the north and Tibet in the east, the twin valleys of Lahaul and Spiti are nature at its wildest. The region remains cut off from the rest of the world for much of the year. It was closed to visitors, till recently, because of military and political reasons. The area encompasses glaciers, high ridges, broad valleys, pastures and has a minimum elevation exceeding 3000 m. This is a high altitude cold desert dotted with famous monasteries, villages dotted like oasis in a stark, brown and dry landscape, miles of rolling pastures, 6000 m peaks and swollen rivers which turn into mere trickles in winter.
Lahaul and Spiti are two remote Himalayan valleys of Himachal Pradesh lying on the Indo-Tibet border. Strange, exciting, primitive, these valleys are incomparable in mountain scape, in the rugged beauty of their rocky escapements and the splendor of their snow covered peaks.
Lahaul is marked by a central mass of uniformly high mountains, massive glaciers, passes, lakes and gushing rivers. The two rivers, Chandra and Bhaga, which rise on either side of the Baralacha La, flow through the narrow Chandra and Bhaga valleys. Lahaul is a land of fascinating Buddhist art and culture. Often called as the 'middle country', Spiti is a cold desert regarded as a "World within a world" and "Palace where the gods live". The monasteries of Lahaul-Spiti are rich repositories of ancient murals, thankas, woodcarving and golden images of Padmasambhava
SPITI VALLEY : Spiti is the sub division of Lahaul & Spiti district with its hqrs. at Kaza. It is called "Little Tibet" because it has almost the same terrain, vegetation & climate . Spiti also means "Middle Country". It lies between Tibet, Ladakh, Kinnaur, Lahaul & Kulu. From Shimla via Kinnaur there is a motorable road which remains open upto Kaza for 8 to 9 months. About 10kms. ahead of Pooh, satluj enters India near Shipki la & Spiti river joins it at Khab. The road then goes to Sumdo via Hangrang valley. From Sumdo Spiti valley starts. The Spiti river flows fast through deep gorges at some places. The valley is not wide but there are villages and some fields where people grow barley, buck- wheat, peas & vegetables. It has an area of 4800 sq. kms. Some inhabitants have adopted Budhism as there faith and Bhoti is the spoken language. The people are simple and honest. The main Spiti valley is split into eastern and western valleys. They are connected with Ladakh & Tibet on eastern side & Kinnaur and Kulu on western side through high passes.
Climate: Lahaul's climate is very much similar to that of Ladakh and Zanskar, which border it to the north. Beyond the reach of the monsoon, the valley sees little rain in summer, when the sun is strong and the nights are cool. Between late October and late March, heavy snow closes the passes, and seals of the region. Less rainfall in both valleys enables climbers & trekkers to enjoy a long and unbroken season in perpetual sunshine and explore the wilderness and grandeur of the inner Himalaya. This unique feature makes Lahul-Spiti as an ideal destination for tourists and trekkers in the month of July, August and September.
