It was a little hard to hike through an unshaded volcanic island under strong sunlight, but it was a fascinating experience to see sulfur gas seeping out from under the ground. It was fun to visit not only Santorini Tira Island but also the surrounding volcanic islands and see the magnificent view from the sea.

It’s great value for money. It covers everything and not too rush either. I took the last trip of the year, which is in early November. Sea water might be cold for some people. Overall it’s good trip

Great excursion! All very well organised and extremely well thought out. Easy travel as we were picked up from local spot, boat journey was good as not too crammed and the guide was very informative!

Super well organized. The guide on the island was very well informed. Great to get the full history on the great eruption.

All good. Happy and enjoyable cruise. Host was lovely and crew very helpful…now why I need to do 100 characters for this review I dont have an idea..😆

This was an amazing experience. As if sailing round the Caldera wasn’t enough the stops were all fantastic. Our guide Spyros was lovely, we didn’t know that the tour was guided so that was a nice surprise, he was very knowledgeable which we absolutely loved. The trip is fantastic value for money. I would highly recommend

I paid extra to be picked up at the tour office in Fira. I didn't expect so many people to be on coach or even on the boat cruise. The were two boats. The English speaking group was split into two, one with the English/ Spanish boat and the other on the English/French/ German speaking boat. The was plenty of seating on each boat and everyone could get a good view and shade. Our guide, Spiros seemed to be extremely comfortable in English/French/ German and could even tell jokes in each language. For 5 Euro, the hike up the volcano was worth it. It's about a 25-30 minute walk up. It's not that high, nor steep but a lot of the path consists of volcanic stones/sand so I would wear shoes with decent grip and protection. I wore trainers. Also bring sunscreen. The views from the top of the volcano are very good and you can see the surrounding islands which formed the caldera. Spiros explained to us some of the history of the volcano. Next stop was the hot springs of Palea Kameni island. The said you needed to be a strong swimmer and the swim was about 60m. I stayed on the boat to watch but it seemed to be more than a 60m swim to me although they do supply swimming noodles and from what I gather there's a rope after about 20m and rocks that you can put your foot on. The water is cold and the hot springs aren't that hot. Also do not bring a light coloured swimming costume as it will get stained by the minerals. Lunch at Thirasia Island was good. I had a swordfish souvlaki. Good views from the steep walk up the hill. This was a very good value boat cruise. I would recommend this trip,

Enjoyed the boat ride from island to island, hiking around the "active" volcano, jumping into the ocean and swimming towards the hot (but actually cold this time of year) spring and ending of at the final island for lunch. Minor downside was guide was selectively friendly towards guests and downright aggressive to one guy (for good reason as he wasn't sure which boat he belonged to but still).

Excellent trip although I would have preferred slightly longer in the hot (warm) springs and less time on Thirassa. Toilet isn’t great on the boat.

NO 1 TIP! - If your staying in Perissa,dont pay for transfers or buy the excursion on the streets. Instead buy the trip directly on tripadvisor and hire a little car for the day which cost 35 euro. Its cheaper, its a nice little drive, the car parks are free and you can venture on to oia for the evening to see the sunset which isnt much further. Well worth going, the volcano isnt quite what you think it to be and the hot springs arent really hot, but honestly its a great day out on a pirate ship. I enjoyed the hike to the top and the swim to the springs was gorgeous. The trip also takes you to Thirassia for a few hours which was on my to do list anyway so all worked out great. The only real criticism i have is the guides are italian or french so its very hard to actually follow what their saying when your in the blistering heat with a load of people crammed together trying to listen. All in all a fab day and probably best thing I did during my time on Santorini.

Excellent trip. Plenty of time at each site. Tour guide spoke English and French very well. Would so again if went to the island again.

Walk to the volcano and swimming in the hot springs were amazing. Great guide who provided great information about the history of the islands.

Great experience! Guide did an excellent job explaining all the details about the vulcanic eruptions on Santorini Islands which once was one big round island instead of 3 seperate ones. Staff was punctual and offered us an amazing 6 hrs with wonderful views.

It was a great day with very knowledgeable guides the hike up is a bit strenuous but well worth it The crew was great highly recommended

The sunset cruise was great . The boat was very smooth & the crew were very friendly ( apart from the girl behind the bar) . The cruise was very smooth. We stopped at the volcano . It’s a steep walk up to the top but the views were breathtaking . You pay €6 to go onto the volcano. We then went onto the warm sulphur springs. The water in the springs section was very warm . Word of warning ,west very old swimwear that you can afford to throw away . The sulphur turns your swimwear brown. Also do not wear any jewellery . Then stopped to have a buffet on the boat before moving off to see the sunset by the volcano which was beautiful. The buffet was surprisingly yummy and filling. And you are given wine or water. It was suppose to be a 5 hour dsy but ended up a 8 hour day.
