“Fantastic day out on the water exploring the smaller islands of Santorini. Hike up to the active volcanic crater was very cool and I'm glad we decided to jump into the water at the thermal springs. I would recommend wearing your bathing suit (not just bringing) since you must jump straight off the boat to swim to the thermal bay and the bathrooms on board are tiny. On Thirasia the hike up the many steps was very worth it to get delicious frappes and baclava from Fyrgano up in Manolas. The tour back around the perimeter of the caldera was equally amazing with fun music, a spontaneous dance party and…”

“Agents for Viator , Santos Star were unorganized and could not find our reservation. I would suggest that you print out your confirmation as Santos has no public Wi-Fi. After looking at our information and calling someone they found that we were registered for the tour . I would not recommend this tour to the volcano and hot spring as getting to the top of the volcano was a difficult climb and while the view of Santorini surrounding islands was spectacular the volcano itself was just a rock creator. The swim at the hot spring required jumping off a boat and a swim of over 30 yards before you got…”

“Amazing day for the value. Not overcrowded as we thought it would be. the 2 hours of free time was great as we just went far from the restaurant area and just snorkeled the rocks off the island and had time to eat still. Only note/recommendation i would have is try to get in the water first for the hot spring as the 30 min will be short if you wait 10+ to get off. people are slow at jumping off the boat :)”

De plus, c’est vraiment compliqué retrouver son bus au retour, aucune indication sur ceux-ci. Très peu de temps aussi au sommet du volcan puisque le guide parle en anglais en premier donc ça donne peu de tenps au Franco de gravir le volcan par la suite.”

Vassili our captain was extremely skillful with the boat and took us as close as possible to some of the volcanic formations. His knowledge about the area and the recommendations he gave us to visit were highly appreciated and turned out to be amazing!!
