Here you can have an idea of how to getting around Kalymnos.

Kalymnos Airport is located about 3 km from the Pothia. Here  land only domestic flights that connect daily Kalymnos with Athens. In the capital  town is  the main port  where dock most of the ferries from the other islands,  Myrties harbor, however, offer connections to Telendos, Leros, Patmos and Lipsi. In Vathi harbor are moored private and excursion boats

Pothia is located in the south part of the island and from there branches off the three main roads connect  all the villages and beaches. Distances are little and getting around is very simple while the roads are in good condition with little traffic. Although the bus service connects all locations are infrequent and not very efficient, so it is advisable to rent a car or a scooter.
