We have booked a morning volcano tour (sold by Greekholidays Travel and operated by Kamari tour). The tour has been canceled but nobody has informed us. We have been brought to the port by bus with no boat for us at the end. The agency has organized our way back to Fira but it was a complete lost day and a big deception to miss one of the must see of Santorini.
