Vulcanic trip, Thirassia, Oia sunset - Good organized trip. Very good value for the money. Perhaps a little to high music at the back of the boat.

Fantastic day - Excellent day and very complete, our Spiros Guide was great and humorous! The excursion to the volcano very sporty but an extraordinary view of the caldera! The small break hot spring funny enough to see all the tourists fried under arms to the spring. The stop on the island of Thirassia was out of time, lunch view on turquoise water and boats. The boat trip was of good duration very appreciable to admire the facades of the different cities. And the stop on Oia was majestic with its sunset.

Great way to spend the day - It was a long and eventful day, but every second of it was worth it. Hiking up to the volcano was very cool, and jumping out of the ship to go swimming in the "hotsprings" was also an adventure, even though the water in the hotsprings is about as warm as the sea. After the sailing, having free time in Oia and seeing the sunset there was magnificent. Loved every minute of the trip. Great job as usual Viator!!!!

A little disorganized, but beautiful and overall worth it! - Overall, the tour was worth it! The hike at the caldera offered beautiful views of Santorini and the surrounding area. The "hot springs" weren't hot, but still warm and a very unique experience! Thirassia was a nice stop for lunch, and there's a couple souvenir shops if you're interested. The boat itself had a lot more people than we expected, but we still enjoyed the ride and it was still a very cool, unique experience to be sailing around the Aegean Sea. There are bathrooms on board the boat, as well as a small bar with drinks for sale. After the cruise, we were supposed to be bussed to Oia. As other reviewers have noted, this part is rather confusing. While on the boat, they had announced to get on "the bus on the right" to go to Oia. Once we got off at the port, all the buses were parked in a group and it wasn't clear at all which bus to take. I showed our ticket to a bus driver, and he pointed us to his bus. He then drove us back to our pickup spot, not Oia. He emphasized it was my mistake because I did not point to a bus route on the ticket when I showed him? We ended up driving ourselves to Oia, as we had rented a car. Oia was very crowded at sunset, as expected, but it was beautiful and nice to see. It was annoying that we had to drive ourselves, but if you can figure out their bussing I would still recommend including the Oia sunset as part of your package.

Amazing tour but terrible errors on the pick-up location and time - Amazing tour, very knowledgeable guide. Very helpful staff on the boat. Very nice comfortable boat. Really enjoyed this full day tour and sunset in Oia :) 😀 But...Didn't give the best mark because there was a huge confusion about pick up and drop off point and time. We selected a pick-up point, but on a ticket given to the driver, the pick-up point was completely different. When the driver didn't find us. They didn't call us they simply sent a text about no show. Thx god, we managed to catch the bus in a different location, but we were very short of missing the tour all together. 😞

I expected more - Gostei: Good communication, excellent punctuality. I didn't like: Walk crowded, do not warn that in the place of the volcano if you do not want or can not climb, you have to stay inside the boat, because there is nowhere to walk.
