Auli is an awesome placr to visit that place have an awesone view which you will enjoy and its trek is also nice! But some where group of 40 member will be a problem so make it all neccesary arrangement
Hi Madhan, Auli is quite chilly (-8 to 4 Celsius) and snowy in December. If your team members are up for some snow and cold then it is a beautiful place in the winters. Otherwise, the best time to visit Auli is from May to October. December is ski season so your team members can participate in that. Besides skiing there isn't much else to do there in December.
If you want to experience snowfall then its the right time. You can enjoy trekking in snow meadows. Skiing in Auli is best of all. Chair cable car is another attraction. Dont forget to try authentic garhwali cuisine . Kachmauli and singhori are must try dishes. https://www.funstay.in/homestay-in-auli-himachal-pradesh-india You can check out the following link as they provide amazing stay midst of beautiful meadows.
