Good tour, got picked up near where we were staying which was nice but the bus was a little late (not really an issue). When we arrived at the port, we got on a boat fairly swiftly and it was very up and downy (which is, in fairness, not the fault of the business). We toured the volcano, hot spring and thirassia which was really nice to see. Would have liked a bit more time at the hot spring but other than that, pretty decent tour. Would recommend

Amazing boat service.i would recommend getting pick up at the Caldera store itself as there is no confusion to store it near mcdonald's easy to find once on the boat make sure you book the sunset one as it offer amazing extra such as a sun bathing area at the front of boat. Stops to see the volcano for €5 per person, also a swim and to see the island Thirasia but can't enter the island due to the earthquake but can go for another swim, whilst stopped by the island you will be offered food and dessert with a view and you won't be disappointed

We had sunset tour with a dinner. It is great adventure for a family where you can see the volcano, swim in two different areas, have a nice dinner, see sunset and… dance zorba. Everything is well organized. We were picked from the house and drop off during return. I recommend to try!

We enjoyed the Sunset cruise tour yesterday. Eight hours on the water went by pretty quickly. Sightseeing was very good and the buffet, while tasty was not as hot as ot should have been. The two swimming stops, including the sulphur spring, were good. The boat was crewed well. I inquired to purchasing a crew t shirt, and sadly, there were none available. The Captain had one embroidered polo and gave it to me. The shirt was too small for me and so I returned it to him with my thanks.

We took a caldera boat tour in Fira, and it was an incredible experience. The boat ride offered stunning views of the volcanic landscape and the sparkling Aegean Sea. We sailed around the caldera, enjoying the unique geological formations and the beautiful contrast between the deep blue water and the rugged cliffs. Sailing for the whole day, we got the chance to see the sunset from the boat-what a beautiful experience it was. It's definitely a must-do activity when visiting Santorini, providing a perfect blend of adventure and breathtaking scenery.
