Your tour escort will guide you along the paths, sharing fascinating stories about its history and eruptions. Wear sturdy shoes and bring water for this moderate hike, which rewards you with stunning panoramic views at the summit. Next, sail to the hot springs at Palea Kameni.

Itinerary

  • Santorini Volcano

    As your boat nears the volcanic island, its rugged cliffs and stark beauty set the stage for your adventure. Step ashore and begin a guided hike along volcanic trails as your tour escort shares the island’s fascinating geological history and stories of its eruptions. A 5€ entrance fee is required to access the volcano. Wear comfortable shoes, bring a sun hat, and carry water to stay hydrated during the hike. At the summit, enjoy sweeping views of the caldera and the Aegean Sea, surrounded by the raw power of nature. Steam vents and volcanic rock formations create a truly mesmerizing, otherworldly landscape. After taking in the views and captivating stories, return to the boat with unforgettable memories. Always follow your tour escort’s guidance for a safe and enjoyable experience.

    1 hour 30 minutes

  • Palea Kameni

    The next stop is the island of Palea Kameni, home to the renowned hot springs nestled on its west side. Here, you’ll have 30 minutes to experience the rejuvenating thermal waters, celebrated for their rich volcanic minerals and therapeutic properties. The boat will anchor approximately 30-40 meters from the springs, and you’ll need to swim this distance to reach the warm, orange-hued waters. Surrounded by stunning volcanic landscapes, this is a rare opportunity to immerse yourself in nature’s healing embrace. Please note, this activity is best suited for comfortable swimmers, as the swim requires confidence and stamina. For those who venture into the waters, it’s a moment of pure relaxation and connection with Santorini’s unique volcanic energy. Afterward, return to the boat, refreshed and recharged, to continue your unforgettable journey.

    30 minutes

  • N/A

    The final stop of your journey is the picturesque island of Thirassia, a quiet gem in the caldera untouched by time. Here, you’ll have the opportunity to explore traditional Greek villages, stroll through charming narrow streets, and admire breathtaking views of the Aegean Sea. For those seeking relaxation, unwind by the waterfront or enjoy a refreshing swim. Food lovers can indulge in a delicious meal at one of the local tavernas, savoring authentic Santorini flavors. Whether you choose to explore, dine, or simply relax, Thirassia offers a perfect glimpse of the tranquil island life before heading back to your starting port.

Published on Nov, 2024

the tour was great and the staff and organizer were very helpful. the boat was clean and they were on time

Definitely recommend

Published on Nov, 2024

Great day out! Would highly recommend. This one does the volcano hike first and then the swim in the sea / thermal pool. Our guide was very informative, which really added to the experience. The stop off for lunch was lovely, and amazing views of the caldera and islands throughout. Very good value excursion.

Beautiful Day Touring The Caldera

Published on Nov, 2024

This tour was a great way to visit the islands inside the Santorini Caldera. The boat was comfortable. The bathrooms were clean and the crew were pleasant. We didn't walk up to the Volcano because it was a steep climb so we remained on the boat. I would recommend this tour. We are older and the company picked us up close to our accommodation. They were prompt and courteous.

Lovely day out

Published on Oct, 2024

We did the 6hour tour, the itinerary was very much as described. The climb on to the top on the volcano gave spectacular view of the Caldera. The swim in the hot springs was a invigorating and you do have to be a good swimmer as the current can be strong. The return trip to Fira was along the cost of the main island. Out guide (Georgia) was very good and gave informative commentary. This boat trip was a nice break from all the climbing/trekking we did to explore Santorini.
