Most tender boats drop at Fira’s old port, where vehicle pickup isn’t possible; you must take the cable car to the meeting point and arrive at least 60 minutes before departure.
The springs are warm but require an approximately 100m open-water swim from the anchored boat; anyone uncomfortable with open-water swimming should remain on board or join the other calmer cove stops.
A BBQ featuring shrimp, chicken and sausages plus Greek salads, desserts and an open bar with wine, beer and two cocktails per person are included.
