Tso Moriri to Tso Kar
Ladakh&rsquos high-altitude lakes are among the special delights awaiting the visitor. A trek between two of its lovely lakes, Tsomoriri and Tsokar, is a good way to throw adventure into the package but, as with all adventure activities in Ladakh, this is not a fly-in, fly-out kind of trek &mdash you&rsquoll need to be able to spare about 10 days, because doing this trek involves first spending at least a day in Leh, acclimatising to the higher altitude, followed by a 215km drive to Tsomoriri. Ideally, try to spend another day or so at the small village of Korzok on Tsomoriri&rsquos shore before you begin your walk to Tsokar and this trek can be both easy and comfortable. Route Tsomoriri-Gyamashama-Rajungkaru-Nuruchan-Tsokar duration 4 days. Grade - moderate. Contact Dreamland Tours (01982-250784, www.dreamladakh.com
Kuari Pass
The Kuari Pass trek, popularly known as the Curzon Trail after Lord Curzon&rsquos trek to this region in 1905, is one of the loveliest and most popular treks in the Garhwal Himalaya. The trail takes you through villages, rolling bugyals (meadows), dense forests of oak, pine and rhododendron, and to mountain lakes like Gohnatal. The main attraction is fantastic views of Nanda Devi and peaks such as Trishul, Kamet and Chaukhamba from different points en route. Altitudes on the trail range from 1,219m to 4,267m &mdash giving you a chance to see a whole variety of Himalayan birds (the most special of which is the Himalayan monal). It&rsquos worth climbing up to the highest point on the trek, the Kuari Pass, in time to see sunrise over the peaks. It&rsquos also possible to make a detour to Roopkund, the &lsquomystery lake&rsquo. People have been visiting it out of curiosity after a local forester discovered more than 300 skeletons in the lake in 1942.
