KTEL Buses (Suburban) There are two KTEL services in Crete: the KTEL of Chania-Rethymno and the KTEL of Heraklion-Lassithi. KTEL buses are green. There are daily and regular schedules between the four main towns of Crete (Chania, Rethymnon, Heraklion and Agios Nikolaos). Also from the main towns, there are regular buses to the largest villages and main tourist places of the prefecture. For example, from Chania Town there are regular buses to Kissamos, passing from all the tourist places on the northern coast of Chania.
