The main public bus service is by Rapid Penang and it covers an extensive area both on the island and mainland. It also operates a Free CAT (Central Area Transit) bus service within George Town. KOMTAR Terminal is the central transfer terminal for buses that covers the whole of Penang Island. Simply ask around or look out for signboards to find out which bus route serves you best. Upon boarding the Rapid Penang bus, inform the driver of your destination, pay the amount required and receive a ticket for your trip. Remember to prepare exact change as no change will be given back as all buses do not carry change for safety reasons.
