Rhodes has a wonderful infrastructure of bus routes throughout the island, not just to the villages but also to the main sight seeing spots around the island. Lots of regular buses and very cheap tickets make it a popular transport option.
Catching the bus is, however, still a slightly disorganised sport, which can make for an interesting adventure-or possibly misadventure, depending on how you want to look at it in the heat of the day!
The main bus stand is behind the Mandraki market in Rhodes.
