A little known fact about Santorini is that there are roughly around 30 taxis on the entire island. After an initial struggle in 32°C sunshine to find one such elusive taxi we arrived at the island's main square overlooking a dazzling azure lagoon. There are two tiny volcanic islands in its centre: Nei Kameni and Palea Kameni.
It is picture postcard perfect. Little white houses with bright blue rooftops dot the cliffs on the water's edge. As we peer down, there is just one question on our minds: how do you get down there? The answer: you walk.
The lagoon and its surrounding coastline is better known as the Santorini caldera. It is the only caldera in the world that is sunken (for those not familiar with geographical features, a caldera is a crater-like aftermath from a volcano).
In a haze of whitewash we meander down the tiny sloping pathways towards the romantic village of Imerovigli. It is one of three main settlements dotting the rim of the caldera, the other two being Fira, the capital, and Oia pronounced 'E-ah'.
