Make your way to the port of Piraeus, Athens. From here catch a boat directly to the island of Santorini in the Cyclades. From the port at Santorini you will be able to take either a boat, a taxi or a bus to the town of Oia, which is at the northern tip of the island. In Oia you will need to make your way down to the sea. The easiest way to do this is to go down the steep steps which start at the point where everyone gathers to watch the sunset. There are donkeys here to help you. You can not miss this spot and if the sun is not setting when you arrive just ask a local where this spot is. At the bottom of these steps follow the path to the left which skirts the bottom of the cliffs. Before long you will see an island of rock 10 metres or so out to sea. You will recognise the jump platform shown in the photo. Swim to the island where there are steps up to the platform. Jump!
