The small tourist infrastructure of Sikinos is concentrated in its port Alopronia. The capital, Horio-Kastro, is perched in the mountains on the other side of the island, 4 km from the port. We have not visited Sikinos yet and the photos of this page were borrowed from Wikipedia.
Sikinos is easily accessible and is located on the ferry line from Milos to Santorini via Folegandros and Ios.
