Sail into the heart of the caldera, a result of a catastrophic volcanic eruption that broke one island into four. We begin the cruise at Athinios port and set sail to Nea Kameni, the larger of the two islets in the centre of the caldera. Here you have the thrilling opportunity of hiking to the rim of the crater; dare to walk around the edge whilst taking in the views over the moon-like landscape (entrance fee not included). We continue to Palia Kameni to swim in the green sulfur waters and experience bathing in warm therapeutic mud. Set sail to Thirasia where you can swim in the crystal clear waters and visit Manolas, a cobble-stone hamlet perched high above with spectacular views over the caldera, Santorini and beyond. Our cruise then takes us to the northernmost tip of Santorini to Oia, the jewel of the island. Whitewashed buildings and bright blue domes sparkling in the sunlight form a picture postcard view you won’t forget. There will be a brief stop for those who chose the option to have free time in Oia to disembark before continuing the cruise back to Athinios port. Option - Tour with Free time in Oia - Total tour duration 10 hours Continue your tour with a visit to the renowned village of Oia. Once you have disembarked, you can take the steps or take a donkey ride (not included) to the village. Enjoy free time to admire the magnificent panoramic views and the spectacular sunset. After the sun sets, make your way back to the port where you can enjoy a relaxing cruise back to Athinios port.
