I took the ferry today from Penang Island to Butterworth and back. The trip to Butterworth is free, on the way back your fare is just RM1.20. As it was around sunset on the return journey, I have some great snaps of the sunset that I'd otherwise have missed out on.
There's nothing to do in the immediate vicinity in Butterworth once you get off the ferry, however the bus terminal here has a range of local buses that will take you to a variety of shopping malls such as Sunway carnival, the Megamall and Tesco. You can also take buses long-distance and taxis are available also. I took one of the local buses today to Sunway carnival mall and on to Tesco. Just RM2.00 to both - I love taking local public transport as it gives you a glimpse into daily life that you'd never see otherwise!More
