A place to call home
Reach Folegandros either by regular ferry from Piraeus, or by high-speed boat during the summer months. The trip lasts about 6,5 hours by ferry and approximately 4 hours by speed boat. There is also daily connection between Santorini and Folegandros and other islands too. Folegandros has no banks but 4 ATMs. There is no hospital but a local Medical clinic, and a pharmacy.
Since the island has only a couple of buses and one taxi, a car hire will be a convenient way of exploring the island which will give you the freedom you wish.
