Sorry for late reply. No internet in remote places of Ladakh. Yes Jispa to sachu is easily doable in a day. Lots of tents. However go only after having diamox and acclimatization as Sarchu is at a high altitude compared to Jispa.Duster AWD is wonderful and have amazing capabilities. It can handle this route easily. Thanks for all the details, enough to boost confidence. Now I am getting tempted to accompany them up to Sarchu. I think a day trip from Jispa to Sarchu ( i.e. Jispa-Sarchu-Jispa ) should not be a problem. Am I missing something ? Can you please give some details about tented accommodations in Sarchu this year. Any mad rush ? Hope not asking too much. My best wishes are with you, enjoy your journey.
