Santorini is a spectacular sight, especially when approached from the sea. Steep cliffs rise dramatically from deep azure waters, with the capital Fira located 1,000 feet above, accessible only by donkey, cable car, or on foot. The views from the top are unforgettable, with stark white-washed buildings scattered along the clifftop. Santorini has a history of volcanic activity, and some say that here in the ruins at Akrotiri lie the remnants of the lost civilization of Atlantis.
