Post monsoon is just perfect time to visit places like Kasol in Parvati Valley. Its all lush green during September and October. Kasol is a small hamlet and few nearby places like Malana, Chalal and Tosh still maintains that old Himalayan charm. The best way to enjoy the scenic beauty is on foot and stay in local homestays. Enjoy evenings at a cafe like Moon Dance, Jim Morrison, Sunshine, etc. Travel in a responsible manner, just respect the nature and the locals!
No! everything is pretty fine with the place. Just be sure with the hotels/homestays you are pre-booking in Kasol. Look for some stay options in Kasol here: https://www.tripoto.com/hotels
