Set sail from the port and head to the active volcano of Nea Kameni. Hike to the top to see the inactive craters and the active one, and enjoy stunning views of Santorini's caldera.
Next, continue to the island of Palaia Kameni, where the hot springs are located. Anchor a few meters outside the small bay of Agios Nikolaos, and swim a short distance to reach the famous mud baths of Palaia Kameni, where the water temperature is 20-25°C.
Then, sail to the island of Thirasia and enjoy 2 hours of free time. Explore the island, swim in the crystal waters of Korfos, eat at the local taverns, and take unique pictures from the island bay with a nice view of Santorini.
After the island of Thirasia, start your return to the port by sailing near the volcanic cliffs of Oia and the caldera, a perfect opportunity to take pictures of the unique scenery.
