This outdoor spa has numerous geothermally heated pools, each held at a different temperature. There are plenty of lounge chairs around the pools, there's a great cafe, and there is also an indoor swimming pool. Go early and spend the day. If you can, bring your own towel and swim cap to avoid that expense.

If you like to spend your quality time in well organized surroundings, with lots of rules of what do do and what not, that is your place. The restaurant is very nice and reasonably priced. But hot water you can get at every corner of that island. And much cheaper.

AMAZING. INCREDIBLE. SUPERB. This is an absolute must-see in Ischia! The grounds are immaculate and the spa experience is wonderful. My girlfriends and I had a lovely and relaxing day of pampering on the idyllic Ischia. We loved every moment of our time spent here. It was not crowded, offered a fantastic variety and just made our trip complete. Please... More

It took us almost 25 minutes where to finally go.... More

Maybe it is a bit too expensive - 30 euros...but for us it was worth every penny... brilliant bay, fantastic termopools...after them you feel 15 years younger...

I was NOT disappointed by the time I spent at Giardini Poseidon, Ischia, even if the entrance fee was 30 Euros for the day (reduced to 16 Euros around 7 p.m.). The treatments are extensive and extremely reasonable and the staff are very professional, and focus on your relaxation and enjoyment. For example, reflexology and a body massage lasting 1... More

Kneipp pool is the best and Japanese pool. I enjoyd natural sauna too. Wonderfull area with many and many flowers, amazing hibiscus and small peperoncino. You should visit this place. Have a good time here :-) V.

Excellent day out. Visited each time we've been to Ischia (and I am slightly addicted), and I never tire of this. A perfect way to relax.
