Taxis are an excellent option for visitors who do not wish to drive during their stay in Santorini and are the only non-driving option after midnight which is when the busses stop running.  Taxis in Santorini are supposed to have fixed fares, but visitors should discuss rates with drivers before accepting rides.  This is particularly true for when visitors hire taxis for day-long tours of the area.  Visitors should also note that if they call for taxi pick-up outside of the main area of Fira, there will be an additional charge for the distance it takes the driver to drive to Fira.The taxi service phone call center is 2286022555. However Taxis are not cheap in Santorini. There are also buses which are cheaper but without an accurate schedule.

A moto or scooter rental cost less [13-17]euro/day but it seems to be dangerous for new or unexperienced drivers because of traffic and serpantine and narow roads  . If you do rent one make sure you get a helmet and wear it.

The roads in Santorini are sometimes not well-maintained and it is important to be very alert when driving, especially when driving a moped.  Additionally, there are strict parking laws in Santorini.  Cars which are parked illegally are not only fined but also have their license plates removed.  If license plates are removed from rental cars, visitors must go to the local police station to get them before returning the car.
