The first eight days of this expedition are acclimatisation, and they are built around Leh. The summit is 6,405 m; you begin at 3,500 m.
Two nights in Leh before anything else
Leh, at about 3,500 m, is where visitors are asked to rest at least 48 hours before going higher. We keep to that. Day 1 is arrival and rest. Day 2 is a hike of 4 to 5 hours, about 13 km, to a ridge above Leh, Chamrang Ri, and back to the hotel to sleep. Climb high, sleep low.
Rumbak, Stok La and back to Leh
On day 3 you drive to Zinchan and walk about 9 km to Rumbak (4,050 m), a homestay night. Day 4 crosses Stok La at 4,900 m and comes down to sleep in Leh at 3,500 m. This is the first real test of the climb: close to 5,000 m, with a bed at 3,500 m to recover in.
A free day, then the Markha side
Day 5 is a free day in Leh: monasteries such as Thiksey and Hemis, or a drive to Lamayuru, whichever suits you. It is rest, and it is part of the plan, not a gap in it.
On day 6 we leave Leh, drive to Chokdo, and walk 5 to 7 hours to Lartsa at 4,800 m, with camping from here on. Day 7 crosses the Kongmaru La into Nimaling, 5 to 7 hours and about 8 km. Both nights are at 4,800 m. The pass lifts you to 5,000 m or more again, now with Stok La behind you.
Then 5,000 m and above
Base camp on day 8 is at 5,000 m, and day 9 is a quiet, active-rest day with technical training. Day 10 climbs to 5,450 m and returns, day 11 sleeps there, and day 12 climbs to 5,950 m and returns to 5,450 m before the move to Summit Camp. The summit day is the 14th day, after thirteen days of gradual gain.
No schedule removes the effects of altitude, and we say so plainly. What the plan does is give your body repeated chances to adapt and your leader repeated chances to see how you are doing. If you are slow on a given day, we adjust the plan, and we turn back when that is right.
