To reach Crete from Greece and vice versa is very easy and fast booking online on OK-Ferry for a low-cost crossing with departures from/to Pireo-Heraklion.
Today the port of Pireo (Piraeus in English) is only used for passenger transport. It is the port of Athens and from there you can take a ferry to all the Greek Islands. The first section is close to a metro stop (line 1). The second part is that of the tourist boats, very popular with young Greeks during the evening due to the presence of many restaurants and cafes. Also in the marina, which is connected by a bus, moor the yachts of famous Greek shipowners.
Heraklion or Iraklion is the largest city of Crete. Here is the biggest naval port of the island. Here stood the ancient Roman city of Iraklia, the port of Knossos, which, after the Arab occupation of the island in 824, was one of the busiest ports in the Mediterranean.
In 1061 the Byzantine emperor Nikiforos Fokas conquered the city that will remain under Byzantine rule until 1210, when it becomes Venetian as Handax or Candia.
Under the Venetians began the construction of the castle that dominates the city today, and during the Turkish occupation the city resumed its old name of Hiraklion or Megalo Kastro (Great Castle).
