Donkeys are an integral part of the island, as well as an attraction. Therefore, you should not miss the opportunity for a donkey ride, to experience a touristic but nevertheless unique experience.
They are the most popular means of transport as well as a part of folklore and local culture. Donkeys in Santorini are so trained in the narrow alleys and sloping stairs that there's really no reason for concern.
Usually, the visitors hop on them to go from Fira to the old port (Ormos Firon), as well as from Oia to its port.
The price of a donkey ride stands at €5/person and you can get your ticket at the town of Fira.
