The best time for a trek in Ladakh is July to September . Srinagar is connected to Leh by Zojila Pass. Also start from Kishtwar over the Sersank and Pota La and from Zanskar crossing the Charcharal. The season is also marked by higher water volume in the Indus enabling rafting excrusions from Leh down to Nimo near its junction with Zanskar River.
Acclimatisation is essential.
Day visits from from Leh can be taken to the Buddhist Monastries dotting the Indus Valley. Leh bazzar it-self harks back to the oldest trade routes to Tibet. Four main routes pass up to 5000 m converge here from Lahoul in the Chenab valley, Kishtwar, Suru Valley and Leh. Khardungla at 18,3000 ft for the Nubra valley and Taglangala at 17,500 ft on the Manali road. The former is Karakoram gate-way to the vast confluence of the Shok and Nubra rivers, Saser kargil peak and its associated lofty ranges.
