You can go following safety protocols but check for the weather updates, and then leave, as roads are getting blocked because of landslide, heavy rainfalls are also there.
Yes , it’s safe but you should take all precautions and safety measures. And you need to even check weather forecast because in heavy rain it’s difficult to travel on hills.
Its safe to visit if you are taking your personal car. And if you are going to manali, I highly recommend allure grand hotel. You can book a stay there it is super hygienic and a beautiful property.
