En route, at several camping sites, one can see splendid streams, grazing pastures, and sharp cliffs. There are several interesting stories relating to this trek. Legend has it that the Pin Parbati Trek was the route taken by the Pandavas when they were leaving for their agyaatvaas (voluntary exile). They had left India for Tibet, through Spiti. The trek takes one further to the Mantalai Lake, where one can camp overnight on the banks of the Parbati River. From here, the trek trails to Pin Parbati valley, to reach the other side of the pass. One gets to cross famous camping spots like Chinapatta Maidan, Mud, Sangam, Dankar and the incredible Kaza region.
After exploring the life and culture at Kaza, the age-old monasteries and Gomp, the drive is down to Keylong at 4551 m. Keylong is the district headquarters of Lahaul and Spiti. The trek reaches the culmination point here and from Keylong, the trekker may embark on a seven km drive to Manali.
The Curzon Trail-Kuari Pass trek in Uttarakhand in the Garhwal Himalayas is another breathtaking trek option. The Kauri Pass is truly a once-in- lifetime experience. The area here is primarily wild as the higher reaches of the river valley have not yet been fully explored. As the British Viceroy Lord Curzon had made the trek to Kuari Pass in 1905, it has come to be known as Curzon's trail The main attraction of Curzon's trail is the majestic view of the twin peaks of Nanda Devi, Kamet, Dronagiri, and Hathi-Ghodi Parvat. It is a popular trek with westerners. Lord Curzon had reached Kuari Pass from Ghat via Ramni. Today, many trekkers prefer to undertake the trek in the reverse direction. They climb the ridge above Tapovan and reach Gailgarh to meet the trail coming from Gorson. One can also reach Kuari Pass from Auli Bugyal through Borson top. Along this snowy trek are forests of rhododendrons, oak and deodar. Himalayan flora and fauna abound here. At Tapovan, there is a massive sulphur spring, the waters of which are believed to contain excellent medicinal properties.
En route, one can get a splendid view of various uncharted lakes, especially the Gauna Lake. The route is through various remote villages in the wilderness where the modernized world has not yet made its foray. The Khal pass is approached through a narrow goat track at an elevation of 3,71 1 metre in the heart of Chamoli district. The glorious view of the imposing eastern peaks of Garhwal Himalayas is enchanting. The peaks appear so close with their glistening snowcaps that one feels they are just an arm's length. The most exciting part of this 12-day trek is the breathtaking view of Mt. Nanda Devi, a sentinel of myriad hues.
