Ko Jum is a relatively small island and most of the population gets around on small 100-125cc motorbikes, which can be rented easily. There is also a local taxi service, comprising a motorbike and sidecar! The roads between the villages are narrow, unsealed, and frequently pot-holed and wet, and can be very challenging for inexperienced riders. There is now a concrete road surface in the three villages and on the stretch between Ban Ting Rai and Ban Koh Jum. A taxi ride from the Ko Jum ferry port to most places on Ko Jum South is 50 baht as of May 2012. You can also be driven around if you want to see the island's main places for 400 baht as of May 2012.
