The first week of the Panpatia Col trek is not a warm-up to be hurried. It is the acclimatisation, and the itinerary is built around it.
Day 2: Auli to Mana
You drive from Auli to Mana, by Badrinath, a day with 61 km on the road and time for the shrine. Mana is at 3,340 m and the night is in a hotel. After Auli, which sits at about 2,600 m, it is the first step up.
Day 3: the road head to the first camp
You drive to the Khirao road head and walk a short way to the first camp, at 2,586 m. It is a low camp and a quiet start. The altitude you gain is small, and you reach camp early.
Day 4: up the Khirao Ganga
A 4 to 5 hour climb of about 8 km takes you to a camp at 3,526 m, which is a gain of nearly 1,000 m. The trail follows the Khirao Ganga through forest and then above the tree line, past the summer settlements of local shepherds.
Day 5: to the glacier snout
It is a short day of 3 to 5 hours and 5 km, over moraine and boulders, to the snout camp at 3,897 m. Nilkantha and Parvati Parvat stand over the camp. The short day lets you sleep high without the effort of a long one.
Day 6: onto the glacier moraine
The ground gets rougher: loose scree and big boulders along the edge of the Panpatia Glacier. The day is 5 to 7 hours and about 5 km, to a camp at 4,289 m.
Day 7: a day to rest
You stay at the moraine camp. It is a rest and acclimatisation day, with a short walk, a look at the icefall and the route ahead, and a session with the gear. It is also the day the group is rested before the camps above 4,600 m.
Day 8: to Parvati Col base camp
A day of 5 to 7 hours and 5 km, over lateral moraine, puts you at 4,670 m, ready for the early start to the col.
The pattern is gain, a short day, a rest, and then the high ground. If you tell us your recent altitude experience, we can talk through how the days would suit you.
