Santorini is the most fascinating island in Greece, highly preferred by thousands of tourists and Athenians during the summer. The local road network is sufficiently good but it gets very busy in summer, so extra attention is required.
The central bus station is in Fira, the capital of the island, where buses depart very frequently. They cover routes to almost all places around the island and certainly to the most tourist spots. This is the chaepest way to get around in Santorini.
Taxis are many in every spot of Santorini. They are found outside the port and the airport of the island, at the central squares of Fira and Oia and also in the beach resorts. They are surely more expensive than the bus but they will take you to your destination faster. You can also book your taxi online.
Renting a car or motorbike is a great way to explore the island. There are many car rentals agencies all around Santorini, however you'd better book in advance, especially in high season, because the demand is very high.
There are daily excursion boats from the old port of Fira to the volcano, the hot springs and the small island of Thirassia. Cruises and excursion boats depart from the old port of Fira, also known as the port of Gialos, while ferries depart from the port of Athinios, 8 km south of Fira.
Donkeys have been a popular means of transport for the locals from the ancient times until our days. Due to the uneven landscape of the island, the donkeys are highly used, especially in the routes from the old port of Fira up to the town and from the port of Ammoudi up to Oia.
There is a cable car from the old port of Fira up to the town.
