As like other years this year season for hills traveling has been started in Himachal Pradesh. March April to Sept November Is considered as best time to visit these places. Because this year temperature has increased a lot even in start of feb so peoples have started to visit cool and green places early this year.
Often in June july few functions are celebrated at Kamrunag and Shikari mata and you will find a much crowd in these hills. Even with lack of resourcess people visit these areas with great interest.
