What the official portal currently lists
For tourism-purpose visits, the official portal describes a one-day to-and-fro permit. It lists valid ID proof, a valid Pollution Under Check certificate, and the vehicle registration date as mandatory information.
The portal currently lists a daily limit of 800 petrol vehicles and 400 diesel vehicles, with online windows at 10:00 and 16:00. It also says permits can only be applied for the next two days and that a printout is compulsory.
