To travel between the locations, a car or taxi would be the most efficient mode of transportation. Renting a car costs around $30-40 per day, and a taxi ride from Akrotiri to Oia costs around $35-40. Keep in mind that parking can be difficult in crowded areas, so prepare for extra time.
If you have more time, visit the ancient city of Thira and the wineries for wine tasting. Alternatively, if you have less time, skip Perissa Black Sand Beach and spend more time in Fira Town exploring the museums and art galleries.
Santorini (JTR) National Airport is located in the southeastern part of the island, 6 km from Kamari Village and 8 km from Fira. It serves domestic and international flights from major airlines. Taxis and buses are available at the airport to get you to your destination.
