Kuari Pass Trek 5 days

Hi,

My girlfriend and I are travelling through the North in May-June. We are going to do a trek in the Uttarakhand region. In particular, we are seriously considering the Kuari Pass trek as it looks awesome.

However, after reading a bit about Acute Mountain Sickness and the risks associated with ascending too quickly, we went back to have a look at the Kuari Pass trek. Please see our proposed itinerary below, as provided by a Garhwal Himalayan Explorer (trekking agency). It would appear that we drive from Joshimath to Auli and start the hike from there at over 3000m. We then proceed to hike up to 4200m. Are we given enough time to acclimatise? I've read in other places that we should spend a few days in the same place just to acclimatise, however in this hike it seems we just push straight through.

If anyone has any suggestions for a better 5-day hike in the same region, please let us know!

Height of Kuari Pass is less than 4200 and I dont think you need to acclimatize for that apart from your regular trek day.
Even in case you do feel some sickness, you can quickly come down to Khulara camp site which is much lower and should alleviate the sickness.
Having said that, if you have any medical condition, you should definitely consult with your doctor.
Dont look for other trek, its a beautiful trek, short and easy.
