★★★★★★★★★★4.5 · 992 reviews · 6 hours · from $41

Spend six hours on a traditional-style boat visiting Nea Kameni, Palea Kameni, and Thirassia. You can hike to a volcanic crater, swim from the boat toward warm sulfur waters, eat on Thirassia, and hear commentary from guides such as Roula, Yannis, or Georgia.

“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 :)”
