Following on from our whistlestop tour of the smaller villages we decide to take a boat trip to visit the volcano that formed the Santorini that we see today.
So we hop on a traditional boat (along with hundreds of other eager beavers) ready to set sail from the harbour and onto see the two volcanic islands of Old Burnt and New Burnt.
Santorini is essentially what remains after an enormous volcanic eruption that destroyed the earliest settlements on a formerly single island, and created the current geological caldera.
A giant central, rectangular lagoon, which measures about 7.5 by 4.3 miles is surrounded by 300 metre high, steep cliffs on three sides.
On the fourth side, the lagoon is separated from the sea by another much smaller island called Therasia.
The trip takes in the island of Nea Kameni,(New Burnt) with its active volcano followed by a stop at the island of Palea Kameni (Old Burnt) with its hot springs.
First up we explore the wild landscape of New Burnt with its various volcanic rocks and craters, where smoke still billows out with strong smell of sulfur. Eyes peeled for pictures of rocks . . .
