Rhodes is pretty much as far east as you can get before you leave Europe. Most people fly there.
Rhodes is not that big a place, almost 80 km from north to south and almost 40 km from east to west. 115,000 people live there full time and must cope with a huge, fluctuating tourist population.
Most of Rhodes´ roads are paved and once you get out of the main towns there are many sinuous and varied local roads winding through the island’s mountainous landscape. Like most Greek roads the surfaces are irregular and poorly maintained. Road signs are only sporadic and you must cope with trying to read Greek script.
There are four main highways in Rhodes. The Greek National Road 95 runs mainly inland north to south and connects Rhodes City with Lindos. The Tsairi-Airport National Avenue runs inland east to west and connects the east coast with the west and the airport. Rhodes to Kallithea Province Avenue runs through the east coast north to south and connects Rhodes City with Faliraki Resort. Finally, the Rhodes-Kamiros Province Avenue runs through the west coast north to south and connects Rhodes City with Diagoras Airport and Kamiros. A ring road around Rhodes is planned.
As it is unlikely you will bring your own car to Rhodes, you can rent one. One dealer, www.rodoscars.gr offers a Peugeot 108 soft top, a Suzuki Celerio, a Mercedes Vito VIP, a VW Passat, an Audi A4 cabrio, an Audi A1 and a Skoda Roomster along with a Porsche Boxster.
If you wanted to try the Rhodes´ roads, you could consider taking a car ferry from Piraeus to Rhodes. You can figure on that taking a lot of time. Salamis Ferries operated a service connecting Piraeus to Rhodes to Limassol and on to Port Said in Egypt. This service has been suspended. If you are prepared to drive in Turkey, you can go to Marmaris and take a ferry from there which lasts only a few hours.
