2.Santorini Volcano and Hot Springs Cruise Tour from Fira Old Port

★★★★★★★★★★4.0 · 1,214 reviews · 3 hours (approx.) · from $36

Meet at Fira Old Port for a three-hour boat trip to Nea Kameni and Palea Kameni. You’ll hike over volcanic ground, pay €5 to enter the volcano area, then swim about 30 to 40 meters to warm sulfur waters. Foam noodles are provided, but the swim suits confident swimmers best.

“This was a very well organised informative and fun 3 hour boat / hike and swim trip. 30e each is not expensive for what you get - but people on a budget need to factor in the cable car costs. We loved it. The boat was great and the staff were helpful and friendly. We read the 1 star reviews before we booked and they were by people who had not read or thought before they set off. Things like it being too hot (in Greece in summer, really?!) or wanting a discount because they didn't want the swim bit (as if that's a thing). It was a great way…”

He is a wonderful tourist guide and quite open for conversation, which makes the difference in a trip like this. Thank you, George! Second, about the destinations: starting by the lake, where we could swim with temperatures of 23 degrees Celsius in the end of October. It was pleasant the presence of these little fishes. The choice of restaurant was also excellent. We got to have lunch by the coast in a nice restaurant that offered fresh fish. Then, we followed to the…”

★★★★★★★★★★4.0 · 375 reviews · 6 hours (approx.) · from $60

“Since we were outside the pickup zone we had to meet the group at the port and that was a little confusing finding them but the tour itself was great. The Thirrasia town itself was not super impressive but it was cute, maybe we should have snorkeled there (and it was an option!).. Would definitely use them again though”
