The island has a public bus service, with buses costing ⬠1.60, ⬠1.80 and ⬠2.20. Buses run between every 30 minutes to every other hour. Timetables are available at website (http://www.ktel-santorini.gr/). The buses occasionally miss trips, and some drivers are less than friendly. Travellers should know that there is also a shuttle bus service (http://www.santorinitrans...) operating to and from the airport and port but requires pre-booking. In addition, there are "hop on hop off" private bus services, (http://www.privatesantori...). Boats also run between major coastal towns on the island.
Cars can be rented from about ⬠45 a day. An international driving permit is recommended. Without one, many car rental places will rent cars, but travel guides have mentioned tourists having insurance problems in case of accident. Scooters and 4-wheelers quads or all-terrain-vehicles are available to rent starting at about â¬15 or â¬30 per day, respectively. A drivers license is required to rent these 4-wheelers. Be aware that most of the people in Santorini are tourists. As a result, road conditions are extremely unsafe, with many people driving by the laws and conventions of nearly every country in the world.
A popular method of getting around is to rent ATVs, though the "all-terrain" part is a misnomer, as most ATV riders are tourists riding on the paved road. ATVs share the road with other drivers and are usually all over the island. The island is small enough to travel around on an ATV, and is a cost-effective way to self-explore the further reaches of Santorini. ATV rental shops are all around the island, so it's best to ask your hotel owner/concierge on the closest/most trusted vendor. You will need your local driver's license to ride one of these, and a helmet is recommended.
Some hotels advise booking a taxi in advance, as there are not enough available taxis on the island during high season. As is the rule in the Cyclades, taxi fares are typically shared between multiple passengers, so don't be surprised if your cabbie picks up more passengers during your trip.
It takes about 50 minutes to drive the island from end to end from Vlichada to Ia.
On foot
Recommended routes by foot include the amazing walk from Fira to Oia note that this walk is less nice in reverse, it can take less than three hours but can be difficult, for up and downhill climbs, the rocky surface at times, and the proximity to unprotected cliffs that drop sharply into the caldera along the caldera, as well as the paths over Perissa Rock connecting Perissa, Kamari, and Pyrgos. The walk between Perissa and Kamari is fairly short via Ancient Thira, while the walk to Pyrgos is somewhat longer, passing through the highest point on the island.
