Hot springs were tepid...

Hot springs were tepid rather than hot. Reasonably long swim off boat. Volcano hike requires a good level of fitness and not suitable for anyone with limited mobility.
Not worth the tour

The tour was not worth it. Having to pay double trip for cable car as well to get into the volcano park makes tour more expensive. The experience is not what was expected. During the tour there is minimal information and on the hot springs the water was not warm or hot at all.
Good 3hr boat trip

Relatively short boat stages. Interesting tour to see and understand the geography/geology of Santorini and the surrounding little islands.
A wonderful adventure!

Even in the heaviest rain our tour guide had seen in the two years he’s been doing this, we had a wonderful time. The clouds made for a very pleasant hike to the top of the volcano. I can imagine on a hot day in July this would’ve been much more of a trudge. The swim to the hot springs, while a bit more exhilarating temperature-wise given it was October and raining, was still an adventure. Here’s hoping someone decides to clean up the falling down structure at the hot spring cove area. That would be the only thing I could say negative about this trip. There were even goats on the island staring down at us as we swam. A really unique way to spend time in Santorini. So glad we did it.

It was a really good experience, but we expected a longer guided tour. The boat was really nice and clean.

Wasn't able to attend and there is no flexibility or refund. I go to the cable cars but there was at least one cruise ship group of passengers that we already in line... by the time we reached the front the boat had already set sail per port rules based on email sent to me when I emailed asking for a bit of time due the line!
Amazing Boat Tour! Great Views

We enjoyed this excursion as we both love hiking and exploring. We had read the description beforehand so we came prepared with good walking shoes, water, hats and sunscreen. Our tour guide only stopped to talk once on the volcano guided tour so we felt that it wasn't entirely guided however this was fine as we enjoyed exploring the volcano ourselves. The hike is definitely challenging if you are a beginner but definitely manageable if you have somewhat good fitness. The hot spring is not that hot, just slightly warm as you swim further towards the sulphonated water but it was refreshing after the tour so we weren't complaining. You definitely need to be a good swimmer to complete this part, not amazing but know how to swim for at least 50-80 metres comfortably. The water was calm and it was a very pleasant swim. The boat ride was comfortable with stunning views and lots of photo opportunities. The staff were friendly too.
