Sailing in the waters of Santorini caldera is breathtaking. The gigantic scale of the unique setting, the majesty of the high cliffs surrounds this ancient crater that was flooded in 2000 years before Christ, is one of the highlights of the cruise. The colourful whites, greys, reds of the volcanic rocks, the blue of the Aegean Sea and the immaculate perched villages form a unique and marvellous spectacle.
