If you have booked for Sabarimala virtual queue tickets ( Digital Q ticket ), you have to necessarily book a KSRTC ticket for travel from Nilakkal to Pampa.
Nilakkal would be the base station for piligrims during this pilgrimage season due to insufficient facilities available in Pampa after flood.
Private vehicles will not be allowed between Nilakkal and Pampa. Only KSRTC will be allowed in this route
You can avail KSRTC online booking from the link provided
