As of now, you cannot take public transport to get to Himachal Pradesh. Your only option would be to either take your personal vehicle or rent one. The movement of interstate buses still remains suspended until further notice. However, according to some sources, the operation of interstate buses will begin after 1st October. There would be another cabinet meeting held during the last week of September or the first week of October to decide on the interstate movement of buses. The priority would be to run buses to Haridwar and Chandigarh when the interstate operations begin.
