LEVEL 1
DEORIATAL UTTARAKHAND
The trek begins at Saari village, 23 km from Ukhimath in Uttarakhand. The village is also the nearest motorable point. For people looking for short hikes in the woods over a weekend, this is an ideal trek. Saari village is four kilometres off a dirt track to Deoriatal. Start your trek in the afternoon when the sun is behind you. It is a 2.5km steep uphill climb and the hike usually takes about two hours or so. You should be in time for a glorious sunset behind the mountains. Once you reach the pristine and tranquil Deoriatal, you are greeted with beautiful panoramic vistas of Chaukamba, Kedar and Neelkanth peaks of the greater Himalayas. The lake is so still that the powdery peaks actually form a mirror-image on the waters. You can camp near the lake overnight. There are local tour guides in Saari village who can help you with tents, a cook and supplies for a fee of Rs 1,300 for six people.

The trek to Dzongri and back typically takes five days, with one day of acclimatisation at Tshokha village. The trek on the first day covers Yuksom-Saachen-Bakkhim-Tshokha (18km).

LEVEL 4
ZANSKAR, JAMMU and KASHMIR
A nine-day trek, covering 70 km and at a height of 11,123 feet, the Chadar trek (known so because it is literally walking on a sheet of thin ice on Zanskar river) is arguably the most adventurous and arduous treks in the country. The trek route begins at Chilling, 162 km from Leh. At Leh, one should acclimatise for at least two days before embarking on the journey. Chilling is the base camp and also last motorable point here. The route goes like this: Chilling-Tilit Sumdo-Singra Koma-Tibb-Nerak and back.

For most of its length between Chilling and the Zanskar valley, the river is confined within a steep canyon, and that's the trail of the trek itself. Mostly flat, the trail is extremely challenging because of its sheer scale and inhospitable conditions- the temperatures fall as low as 25 degrees Celsius. It requires prior training and ample trekking experience. There are myriad guides and trek operators to Zanskar in Leh. The prices per person range from upwards of Rs 20,000, all inclusive.

When to Go: The Chadar forms fully from the 3rd week of January. The trek can be done starting the first week of March
How to Reach: Leh is the nearest airport. It is 162 km from Chilling the base camp
