Santorini
Make sure to be on deck to witness sailing into one of the Aegean’s most spectacular sights: the volcanic caldera that is Santorini’s bay. Rising from the sea, the earth transforms into a wall of stone that looms in striating hues of ochres, grays and pinks. Dotted with the island’s iconic blue-domed churches, the whitewashed village of Fira hovers in the cliffs, bustling with shops, tavernas and a fine museum while clinging to the caldera’s rim.
