A rental car is the practical way to reach the villages, gorges and both coasts of the Rethymno district, since bus service to the interior and the south coast is sparse. Rethymno town has many agencies, a mix of long-established local family firms and international chains, and most will deliver to your hotel, the port, or pick you up at Chania or Heraklion airport. Long-running local names include Arkadi (operating since 1980), Auto Moto Sport (since 1993) and Greenways. Book ahead for July and August when demand and prices peak, bring a credit card for the deposit, and note that non-EU licences may need an International Driving Permit.
