It’s been very effective and fun trip. Volcano island was explored and one live crater was seen. Swimming in the hot spring was also great experiences. The cruise crew was very friendly and helpful, in general, great trip!

Maybe a live tracking of the transportation would help. And also an identifier such as Bus Registration number to identify which bus is ours.

Full description

Set sail from Athinios Port on a traditional wooden boat and explore the natural wonders of Santorini’s volcanic landscape. With live commentary on board, you'll journey through the heart of the caldera and visit iconic spots shaped by volcanic activity.

The first stop is Nea Kameni, the island with the still-active volcano. You’ll have the chance to hike to the crater at your own pace, enjoying panoramic views and witnessing the power of nature up close. Please note that this hike is unguided, so extra care should be taken during your walk.

Next, the boat will take you to Palea Kameni, where you can enjoy a rejuvenating swim in the natural hot springs, known for their high sulfur content and healing properties. Be aware that the mineral-rich waters may stain light-colored swimwear.

The boat will stop in the bay of Thirassia for a second swimming break (weather permitting). Take a dip in the Aegean and soak in the tranquil atmosphere around this traditional island from the water.

The cruise continues with a scenic sailing tour of the Caldera, where you'll be able to admire the majestic volcanic cliffs and whitewashed villages perched above the sea. The tour concludes at Athinios Port, with an estimated return time of approximately 15:45.

This is a memorable opportunity to witness the unique geological beauty of Santorini, combining adventure, relaxation, and stunning views.
If you book the extension option the boat will also take you to a port where a comfortable bus will be waiting to transport you to the mesmerizing village of Oia. Immerse yourself in its unique charm as you enjoy 2-3 hours of free time to wander through the winding streets, soak up the breathtaking views, and witness the magical sunset that has made Oia world-famous. As your time in Oia comes to a close, hop back on the bus for a relaxed journey back to your original destination. Reflect on the incredible memories you’ve made, carrying the beauty of Santorini in your heart. Please meet your bus in Oia at the meeting point 15 minutes after sunset.
