Best Places to Visit in Pakistan This December? Need Suggestions!

I’m planning to take some office leave next month and really want to spend it exploring some beautiful areas in Pakistan. Since December is a colder month, I’m looking for places that are either great for winter views or still comfortable to travel in.

What would you recommend as the best area to visit in December?
I’m open to anything—mountains, historic places, or just peaceful spots to relax.

Where should I go for the best experience? Would appreciate any suggestions based on weather, scenery, and overall vibe!
