Absolutely overrated – the small park, including the swimming area, is nice, but far too expensive for its size. The pools are very small and too crowded for my taste. If you want to soak in hot water, I recommend a visit to Terra Nostra Park.

A wonderful park, but very small. Admission is okay at €3.00 per adult. There are also thermal pools where you can swim, but they are very small. It's also very crowded. To swim there, you have to pay an additional €7.00. I don't recommend it for swimming.

One of the key points of the Island - and the entire archipelago. Site immersed in nature that, like other volcanic calderas on the islands, makes it seem like you are somewhere on dry land, and not in the middle of the ocean.
