Lots of fun for the family. Great hike and great views - This was operated through Caldera Boat tours. The organization was well done. Multiple pickup points were offered. We got a boat with a great captain and even better tour guide. Lots of great information and great fun for the kids. It's a great hike up the volcano. Taking a bathe in the hot springs does require a good bit of swimming skill as you are swimming in from about 30-50m from the hot springs. There's some swimming time also in Thirasia but just like most of the beaches around Santorini, its a rocky beach. To end it all a cruise along the inner coast of Santorini offered wonderful views. All in all very much worth it and very enjoyable.

Pleasant day on the Aegean - Just being out on the ocean and visiting all the wonderful places including the volcano and hot springs, and it all being very well Cordatnated and for the most on time

BOST trip - We loved the guide. Very informative. Hot pool experience a little disappointing. Food at the large port was poor quality and over priced.

Great combination of stops! - Loved this tour! The timing was perfect, the crew was great and the stops were interesting! We enjoyed hiking up to the village on Thirassia and had an amazing meal at fyrgano. We also loved swimming in the volcano water and touring the volcano!

Vale cada euro que pagas - Un tour imprescindible si visitas Santorini. Las explicaciones del guía acerca de la formación de las distintas islas fantásticas y la animación y profesionalidad de la tripulación excepcional. Precio comedido tanto en la actividad como en las consumiciones. En nuestra memoria para siempre quedará el baño desde el barco.

Passeio pela Caldeira. - Muito bom o passeio. O guia mostrou muito conhecimento. O passeio pela Caldeira fo ótimo. Indico sim. ..valeu muito apenas. Imperdível.

Not to be missed - View from the top of the volcano island was breathtaking. Worth the climb! The whole trip was well organised with clear instructions at each stop. Quite punctual too.

Beautiful! - The boat was beautiful, the staff were really friendly and helpful. The scenery was just incredible and gives such a different perspective of the island. I'd of liked more swim time is the only room for improvement.

Not worth for time spent - Swimming in Volcano site is the best part of this tour but there was hardly any time for us to enjoy it. We got only 20min out of boat. Hike was good but day was too hot so perhaps they should have given us more time in water and not on ground. Not sure what was the hurry knowing that most people wont enjoy out in sun. Also time for lunch was nearly two hours on island where there was no other activity to do. In summary more time in spring water and less on ground would have been a much better trip.

Beautiful boat and lovely tour of Caldera - but hot springs were filthy with floating sewage - Lovely boat, great tour of the Caldera by boat - but the hot springs were disgusting with floating sewage - and not really hot - if you swam right in to the shore. The guided tour of the volcano was not informative either. I would recommend not swimming in the hot springs.
