Great experience - Great views, knowledgeable guide and 3 cool stops on the islands. Keep in mind that the first stop will be a track up to the top of the volcano. Bring water and comfortable shoes. The entire trip is about 6 hours. Drinks and coffee are offered on board. Really enjoyed the experience!

Great experience - The guide and crew were knowledgeable, friendly and accommodating. The tour was great, just wear good walking shoes to climb the volcano island for amazing views, and bring a swimsuit if you want to swim from the Aegean into a hot (warm) spring. Our trip lasted 6 hours and ended at Thirasa Island with good restaurant options before we headed back to port.

Amazing tour well worth the money - Amazing tour. Great guide. And well organised. Nice music on the boat. Good way to know just a little bit more about the local area. And see it from a different viewpoint (boat).

Great experience - Easy to find the pick up and drop off location. Tour guide Anna was very knowledgeable, kind and safety oriented. Good amount of time in each place - felt a little hurried leaving the thermal springs but otherwise a perfect day.

Must do activity! - Highlight of our trip. Very good experience but tiring if you decide to do the whole hike up the volcano and swim at the hot springs. Pro Tip: when you visit Therasia, walk up to the town for lunch rather than eating by the Pier.

The best money spent on a boat cruise guide. - Yannis was an amazing guide! He knows 6 languages and did the tour in English and French. Yannis was very knowledgeable about everything about the calderas of Santorini and the boat itself was absolutely gorgeous and something out of a pirate movie! The vibes and music was 100/10 when I come back I’d definitely book with them again.

Anna out tour guide was great. Good value for money too. - Anna out tour guide was very knowledgeable and great at explaining the history of the volcano and the island of Santorini. We got a very hazy day so unfortunately weren't able to appreciate any of the views but I'm sure they are beautiful on a clear day. We didn't partake in the swimming as the temperatures in April are still on the cold side but I'm sure it's lovely in summer. The only downside was the lady checking us in at the office at the port acted like doing her job of checking people in was a major inconvenience to her.

Great experience - Loved the history of volcanos. The time at the hot springs too short. Just enough time to swim to the area, and then had to come back. Everything g else was amazing!
