Actually the whole Himachal is best. But even though u can go for Tirthsn valley, Solang valley, Barot valley otherwise u can also roam in Dharmashala where beautiful cafes specially in macklodganj are there, either u can also go for remote villages.
October is the best time to visit Himachal pradesh. The chill in the wind gives you a hint of what follows in snowy winters in Tirthan valley. Places like Jibhi, gushaini gives you plenty of natural serenity with Tirthan river flowing by the side and mesmerising views of waterfalls and deodar trees. You can also visit Lug valley if you love trekking.
Hi Tanay! Himachal is full of serence landscapes, so its difficult to pin point a single destination! But you could try travelling to Jibhi and surrounding areas. You could also cover Tirthan Valley. Tosh Village is another underrated and fairly unexplored place. You could also try the Parashar Trek. It would definitely be cold, but if you're a trekker, you wouldn't regret it!
