The road network of Kalymnos is quite good with asphalt roads and safe paths. If you want to rent a car or motorbike for your private tours, you will find a few rental agencies on the waterfront of Pothia and in the most tourist spots of the island.
Taxis are also available in Kalymnos. They stand at the central square of Pothia and at the port. From the small port of Myrties, daily excursion boats go to the secluded island of Telendos.
