One of the ultimate adventures you can experience in Santorini is to join a volcano tour. The famous volcano of Santorini is the greatest attraction of the island that has provided evidence of up to 12 large eruptions over the past 200,000 years, while there have been a number of smaller occurrences over the years with the most recent explosion occurring in 1950. The best way to explore the volcano and actually hike on it is through a Santorini Cruise that will actually take you to the volcano, as well as to the small island of Thirassia. The yacht-sailing boat trips also include swimming in the thermal waters of the volcano’s hot springs. Cruise options include: hike the volcano; swim in the hot springs (you can always stay on the boat if you wish); visit Thirassia and explore its villages; stop at Red Beach and White Beach to swim and snorkel; eat lunch or dinner on board and watch the sunset below Oia.
