There are some mooring balls just off Oia on the northwest corner of Santorini, but they were either too close to the land for our boat (14.8 meters) or they were reserved. We ended up leaving Santorini without even setting foot on the island because we couldn't find a place to leave the boat. We were disappointed, but we sailed up to Folegandros instead and enjoyed it immensely.
