Yes, there's an opening between pillar just beside the parking barrier. any bike can easily pass through.

to get to the parking entrance once you reach the top after passing Ria Apartments, keep to your left. immediately after police station there's a left junction. dont miss it as it is a sharp left turn.

head further down, u will see staff dorm on both your left and right (the left one is named RSC something with a guardhouse)
past the dorms keep to your right immediately andyou will see this upward road leading into the parking.
