Halki is a lovely, tranquil place, much preferred by people who need some piece and quiet during their holidays. On such a small island, there is no need for public transport. Moreover, only a few private vehicles are spotted in the whole region and after a certain hour using a car in Nimporio is prohibited. The most usual way to explore Halki is on foot. Also, there is a small boat that carries out short trips to nearby, isolated coasts.
However, in case you feel that it will be difficult for you to move around with your luggage upon your arrival, you can contact your hotel in advance and get informed if a pick up service is provided.
