See the highlights of Santorini on an 5 hours shore excursion, and explore the island from its half-submerged volcanic caldera to the summit of its highest mountain! With a private guide at your side, learn about Santorini's volcanic history while visiting the caldera and Perissa, a black-sand beach. Then, travel through the mountains to a monastery and sample local produce made by the resident monks. Try wine at a volcanic vineyard and winery, and then round off your day with free time in picturesque Oia village before returning to port.
