The main port of Andros, Gavrio, is connected with mainland Greece through the port of Rafina. The trip takes two hours, but if you choose one of the fast ships, it will be one hour only. The daily connections are frequent and during summer and weekends there are more. There are also direct connections with other islands, regurarly with Tinos, Mykonos and Syros and less frequently with many others.
