Crusts of land mark the rim of Santorini’s spooky 10 km wide and 1,250 ft deep caldera. The largest, curving around the northwest, is Thirassia, part of Santorini until the two were blasted apart in 236 BC.
In one of its pumice quarries a Middle Cycladic settlement was discovered, pre-dating Akrotiri, though there are no traces of it now. The main business on Thirassia is growing tomatoes and beans on the fertile plateau; the largest village, Manolas, has tavernas and rooms to rent.
Excursion boats from Oia make trips out to the burnt isles’, Palia Kameni and Nea Kameni (born in 1720), both still volcanically active, especially the Metaxa crater on Nea Kameni, which last erupted in 1950. However, even though the local brochures promise `the strange volcano which cause you greatness’, be forewarned that some people come away disappointed. The tourist trail up the mountain is a bit difficult and stinks of sulphur. Most of the excursions take people to swim in the sulphurous mud nearby and hot volcanic waters around Palia Kameni which is said to be really healthy so try to be tolerant of the smell since it may do you good in the long run.
As you may probably know already, Santorini is one of the most popular Destination Weddings. This is very logical when you think of how idyllic and romantic this island is with its famous sunsets and the incredible caldera view, the volcano and the picturesque chapels.
