Langza is the only place in the Himalayas where one can drive to from the plains 12 months a year. That is because there is no pass that one needs to cross while driving from Shimla. There are two approach roads - from Shimla and Manali. Whereas, it is about 425 kms/18 hrs from Shimla (open 12 months), the drive from Manali (open only from June to October) is 215 kms/9 hrs.
