HOW TO ARRIVE
By plane: Rethymno is situated between the two biggest cities of Crete and has no airport. It is 78 km from Heraklion (or Iraclio, the capital of the island), and 65 km away from Chania (or Hania). In order to reach Crete (and then Rethymno) you can fly directly to the airports of Heraklion (http://www.heraklion-airport.info/) or Chania (http://www.chania-airport.com/). All major airlines as well as low cost companies and charters fly both to both airports. Especially during the summer you can find direct flights from all over Europe. Ryanair flies to Chania and Easyjet, Volotea, Airberlin, Vueling to Heraklion, both of them with direct flights from many European cities. Aegean airlines is the Greek company that also serves the island with inland and international flights. If you do not find a direct/charter flight, you can always choose to fly to Athens (https://www.aia.gr/traveler/) and then reach Crete either by air (Aegean Airlines & Ryanair fly daily to Heraklion and Chania) or
By sea: with the ferry from the port of Piraeus (ANEK and MINOAN lines travel daily to Crete, to the ports of Heraklion and Chania).
From the airport: you can come to Rethymno by taxi (you can find one directly at the airport, 1 h drive, 69-78 euros), bus (1h 15 min from the central bus station, buses depart every hour, ticket around 7 euros) or rented car (approx. 1 h drive, there are various car rental companies outside the airport). The central bus station in both cities is located in the city centre, so to arrive there from the airport you need to take a taxi (10 minutes drive, the fare around 10 euros) or a city bus (20 minutes drive, around 2 euros) and then take the bus to Rethymno.
