2/3 Day trek around Diwali


Armchair Traveller :(
Guys please suggest options for an easy to moderate, 2-3 day trek around Diwali. Preferably in Himachal due to better connectivity. Uttranchal and Maharashtra are fine too.

As an option to this I was thinking of visiting Kasol and then doing trips to Tosh, Chalal, Pulga etc villages. I hear its a decent walk/hike and views are great. My concerns are 1) Is it safe for women & 2) How do I book in advance as Diwali Holidays may create rush.

Another option someone suggested was Kheerganga trek. How will that be around Diwali?
