By ship
Crete has many ferry connections for example:You can go from Pireaus to Heraklion with Minoan Lines (http://www.minoan.gr), to Chania with ANEK Lines or Hellenic Seaways, to Ayios Nikolaos and Sitia with LANE Lines.LANE also operates routes from Ayios Nikolaos/Sitia to Rhodes and other greek islands.In the summer, there are daily catmarans hydrofoils from Heraklion to Santorini. The trip takes about 2.5 hours. Hellenic Seaways and SeaJets offer these sailings.You can also go to Crete by ferry from the Peloponnese Gytheio and Kythira island. This ferry lands on the west part of Crete, in Kissamos port.
The main ports in Greece that ferries come into are in Heraklion, Chania, Rethymno, Sitia, and Kastelli-Kassamos.Since there are no roads along the southwest coast there is a ferry line, (http://www.sfakia-crete.c...) with connections between Paleochora, Sougia, Agia Roumeli, Loutro and Hora Sfakion Sfakia. There is also a connection with the islet of Gavdos, Europe's southernmost point Cape Tripiti.
By bus
Public transportation is fairly frequent and timetables (http://bus-service-crete-...) quite trustworthy. Bus drivers usually divert from their marked routes to enter little villages if asked to do so. Bus services along the north coast and towards the south coast are excellent, reliable, frequent and cheap.
Most of these Bus services are run by Kino Tamio Eisproxeon Leoforon, KTEL, which are groups of families which individually run their own bus companies. This, in turn, creates a much more homely environment for Cretans and tourists and these families provide excellent service and show off their great deal of pride.
Cretan buses stations are very simple for the most part except for in Heraklion which has two major Bus stations one for buses going in town and one for KTEL run buses.
By car
Be careful when driving in Crete, as Cretans haven't got used yet as of driving in a more-than-one lane road national roads were recently upgraded near Iraklion to two-lane roads and will easily drive in the middle between the lanes, trespass the double-line or flash the headlights to drive you into safety lane for them to pass. Stop signs are rarely respected by locals, and the best way to avoid accidents is to reduce speed to the point that you could easily stop the car and avoid collision whenever you approach a crossroad. Stay on the safe side legally in order to maintain your rights in case of accident. Despite the fact that most roads are slippery, Cretans usually drive agressively. You certainly wouldn't have to follow their example.
Taxi services are another great way to get around Crete because they are very cheap throughout Greece. They are a very accessible and easy way to get around large cities like Heraklion and Chania. Greek taxis all work under the Greek State and the Taxi driver must always charge by the meter price which he must turn on as soon as you get into the cab.
There are 2 taxi tariffs in Greece: Tariff 1 is day hours ranging from 5:00am to midnight and Tariff 2 is night hours ranging from midnight to 5:00am.
