Nea Kameni is an hour of loose black ash with no shade on it, and the springs off its flank are warm rather than hot. The 15 below are compared on climbing time, how long you get in the water, and which port they leave from.

★★★★★★★★★★4.5 · 1,302 reviews · 6 hours (approx.) · from $42

Review of Santorini’s caldera cruise to the volcano, sulfur hot springs, and Thirassia, with practical tips on swimming, fees, crowds, and value.

“We enjoyed this excursion that took us to hike the volcano, swim in the hot springs, and visiting Thirassia. We visited in early October so it wasn’t too hot for the hike. The water was a little cold when we jumped in, but we got used to it quickly. The hot springs weren’t that hot but it was still a cool experience. We had gyros for lunch on Thirassia before heading back.”

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

Hike Santorini’s volcanic Nea Kameni, swim toward Palea Kameni’s warm springs, and enjoy caldera views on a practical 3-hour boat tour.

“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…”

Review of Santorini’s volcano, hot springs, Thirassia, and Oia sunset boat trip, with practical advice on costs, walking, timing, and value.

“The trip started with us being collected from our hotel at 9.30am then transported to the new port where we got onto the King Thiras boat. The crew were friendly and well organised. we travelled to the 'volcanic island' with interesting commentary from the excellent guide. The exploration of the island is not for the feint hearted especially in the heat but we'll worth seeing. We went on to hot springs were there was just a short time for people to swim. then it was off to Thirassia for lunch. there are a few places to go in the water here but it's very rocky. After lunch it is a…”

Cruise Santorini’s caldera with Panos and Alex, swim in volcanic springs, snorkel quiet coves, eat local dishes, and watch Oia’s sunset.

“This was (by far) the highlight of our stay in Santorini! Panos and Alex were tremendous, both as crew and as tour guides. Panos has a deep love for the nature all around the island and it is apparent in everything he does. We got to swim in the volcanic waters (which were so warm) and then got a magical tour around all the islands in the Caldera. We mentioned that we don't like hordes of people and Panos took us to delightful remote spots to enjoy the beauty around us. The lunch they served was the best food we've had in Greece. I cannot recommend this tour enough!”

Review of Santorini’s volcanic islands cruise, hot springs, Thirassia, and Oia sunset, with honest advice on value, logistics, and what to pack.

“Tour guide Spyros was very friendly and nice.Very clever to speak so many languages.We enjoyed the tour but there’s one thing that i don’t like with the tour, people who was wet after swimming don’t even bother to get change or put a towel on so that the people who doesn’t want to get wet won’t sit with them or there should be a space for the swimmer to sit after swimming because it’s not fair for the others who doesn’t want to get wet.”

Try beginner scuba in Santorini’s volcanic caldera with patient instructors, reef fish, clear water, equipment, and a 10-person limit.

“This was one of the most anticipated events of our honeymoon for me. I was extremely excited and confident yet when it came time to do it I have to admit I was terrified. Our instructor did a fantastic job at explaining everything and being clear with instructions but for some reason I was still scared when I had everything on and in the water. Luckily he took the time to instill confidence in me by taking baby steps with breathing, slowly descending to practice ear pressure control, and then learning the basics of underwater buoyancy. After doing this I was way more comfortable in just a matter of minutes…”
