Our route for the trek wasn't via Stok village (which is most common and shortest route to take), but the route from the right towards Stok La base, which took us approximately 7 days. The following morning we headed to Mankarmo. From 4270m, we climbed up 4900m and descended to around 4400m. Following the golden rule, "Climb high, sleep low" is exactly what we did to acclimatize.
The trek can be approached from Pin as well as Parvati Valley and both have their own different landscapes to offer. While Parvati Valley (Kullu side) has meadows, deep forest trails and waterfalls, Pin Valley leads you to a mountain desert. We were recommended to start the trek from Parvati Valley since we could expect less snowfall on the route and give us more time to acclimatize. Our first campsite was Kheerganga and and the last was Pin Valley Base Camp 2.
