Definitely recommend - 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 - 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.

Great day! - Superb family day, with 2 children aged 6 and 8 years. We took the boat to the old port of Fira, leaving at the exact time. 1st stop at the Volcano, with explanation about the quality geological activity with Yann in English (and in French because there was quite a lot of French), we then had time to go up and take pictures. Very interesting. 2nd stop at the hot springs: water at 23°C while the sea is at 19°C, about 30 people bathed. Then 3rd stop in Thirassia: 2h break: lunch, or climb to the village of Manolas Return by boat under Oia and along the coast; return a little before 16:30. A very good day!

Half-day tour with ascent of Santorini volcano, swimming in the hot springs and Thirassia island. - Wonderful day with beautiful unforgettable images of Santorini seen from the boat with its beautiful white villages right on the cliffs...The excursion of the volcano ascent was also really nice and Georgia a great clear and dynamic guide! Too bad the option in French was not possible. The hot springs experience was very funny though a bit fast but really good anyway. The island of Thirassia is also very beautiful and the beautiful view too. Atmosphere assured on the boat with catchy music and sometimes some explanations from the guide without overdoing it, it was perfect! Thank you for this beautiful day and these beautiful memories!

Lovely day out - 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.

All in all, an excellent cruise but we felt a little rushed by the staff. - Good cruise arond santorini. Special mention to our guide, multilingual and very friendly. The history of Santorini was well described and very interesting. The visit and swimming in the hot springs was very pleasant although short. The same goes for visiting the island of Thirrasia.

Magnificent views and pleasant cruise - The sailing was pleasant and the crew was lovely. Thirisia (beautiful), the Volcano (interesting) and Magnificent Views. The only point to improve is the boarding at the port of Fira, a bit chaotic but not attributable to Santorini Caldera Cruise Tour, but to the mega cruises and the hundreds of cruise passengers disembarking.

Great way to learn about the history of Santorini - What an incredible (and affordable - at least, in October), way to explore Santorini! This half-day tour was great, although I wish they were able to add an extra half hour to each stop, especially on Thirassia island. We barely had enough time to walk up the stairs to the town and have lunch. It would have been nice to have an extra half hour so we could also add in a swim in the sea. Nevertheless, no complaints :) We learnt a lot about Santorini during the tour.

Nice but a little disappointed - Nice excursion to see Santorini from another angle, discover its history. Guide speaking French, top! To note: if we want to hear all the commentary of the guide in French then we only have very little time to climb to the volcano and go back down, we stayed 2 minutes there and we had to go down again For warm waters, they are not really hot since 4-5 degrees more than the sea water and you have to dive from the boat where the water is at 19°, with a little courage and because of the wind, so in the end, no one bathed. The children were very disappointed. On Thirassia, we stayed 1h50 so too short to go up, lunch and down again. We stayed at the port.

Skip this tour - This is a misleading tour. We enjoyed the history and the hike up to the top of the volcano. The tour guide was very knowledgeable; the volcano experience is the reason I didn't give this tour 1 star. The "Hot Springs" and Thirassia were a disappointment. The day previous to our tour, a local informed us that the Hot Springs weren't hot due to the volcano being dormient. Due to this, I reached out to Viator and received the response that was captured in the picture I attached. When we got to the Hot Springs portion of this tour, the locals were absolutely correct. The tour guide informed us it was around 23 C (73 F) and referred to them as "warm" springs. It was highly disappointing. The last stop was also a disappointment. We were taken to Thirassia for 1.5-2hours. There were only a few restaurants at the bottom of the island where the port was and were told we could hike to the top if we chose. There wasn't enough time to do both eating and exploring. We were loaded up in the boat to go back to Santorini and it took 1.5hrs for them to get us back even though it was all within viewing distance. They took the long way to get there, ultimately to drag this tour out to a full 6 hours. It was completely unnecessary and most people were asleep or disengaged. Overall, I do not recommend. Find a tour that takes you to only the volcano and save your time and money.
