Hi
I think you will get more response if you mention what kind of a holiday are you looking for.
A quiet holiday away in the hills, one with adventure activities or a happening one with lots of hustle bustle.
And who's traveling. Elders, kids, etc.
Auli will be nice and quiet, Manali happening and lively.
There would be a whole lot of other options across the Himalayan region, right from Kashmir to Arunachal.
Srinagar, Pahalgam, Gulmarg in Kashmir. Even Ladakh.
Chamba region, Lahul/Spiti in Himachal.
Auli and similar in Uttarakhand.
Chitwan in Nepal.
Pelling in Sikkim.
Bhutan.
Tawang in Arunachal.
There are lots of professionally managed adventure activities in most of these regions.
Recently came across this exciting video of Sural Bhatori in Himachal.
