If ever visiting Penang island, you should definitely visit Penang hill you can take a bus there as it is much cheaper, than the taxis, but remember to have the right amount for the bus as they do not give change. The fare i can range from 1 - 5 Ringgit to find out which bus goes there go to any backpackers and ask for the bus schedule, each bus is numbered, just look on the schedule which number goes to the hill and wait at any bu stop for the number bus.
