For travelers who enjoy using public
transport to go around, Rapid Penang buses are perhaps the best choice.
This is because: 1) Penang taxis generally don't use meters. 2) Other bus companies are not as efficient as Rapid Penang.
There are three main interchange stations for the buses in island.
1. Komtar Bus Terminal
2. Bukit Jambul Bus Station
3. Ferry Bus Station
In general, if you do
not know where to take your preferred bus, just hop into any bus and
stop at Komtar. Then, take you preferred bus in Komtar because ALL buses
pass Komtar.
