Clean, breathtaking, and so many saltwater spas! It's like a beautiful retreat for body and soul. Landscaping is lovely, the pools are immaculate, and the views from each are truly incredible. We opted for spa services as well - ask for the massage before the facial - else the facial looks ...wonky .. afterwards. ;) The food in the dining area is healthier and very tasty. There is also a sauna in a cave - not to be missed. If we lived here ... it'd be a weekly must.

Never been anywhere like this. Has a beach, restaurant, several pools (various temperatures). Must bring shower hat or shower cap to cover hair. Some people with mobility issues may struggle with all the different steps to go from one area to another.

We have been visiting every year but I can say this year they have only improved for the better. The pools are immaculately clean, water is nice, temperatures pleasant, all is nice The automated locking system is a nice new feature making it easier to go back anytime you forgot something ... Food and coffee was fresh and delicious. The multiday pass discounts were a great deal

Poseidon is a must when you are in Ischia. With 20 thermal pools, a garden which is trimmed to perfection, breathtaking views and a beach to relax, this is the place to be to make your stay on the island unforgettable. And to make you want to come back for more. Go early and grab a place on the beach, as these get booked fast and the beach can get crowded in the afternoon. Follow the directions for the thermal pools and do ask the staff about the benefits, history and tips. Enjoy lunch at the restaurant - only fresh produce and a great selection of meals. Sustainable and plastic free, which makes it wven better!

Scenic half hour drive from Ischia Porto arrived at a peaceful, no children screaming, calm oasis of relaxation. Easy to navigate with not too many steps up to higher pools. Plenty of sunbeds and shade. Restaurant good prices albeit small selection of food. Lovely private beach with lifeguard. All must wear swim hat (can buy from on site shop next to restarant and lockers for Euro 2.50) but this can be your own cap, bandana etc. Half day suited us and felt fair price. Enjoy relaxing - definitely recommend

What a beautiful place and such a relaxing experience. Amazing! I will be back several times. Came with our family and friends - group of 9 with 4 adults and 5 kids (pre-teens and teens). We loved the beach, thermal baths, restaurants and bar. I can’t say enough good things. We come to Ischia often and this was our first time at Poseidon and we were impressed. Came back the very next day. Just wonderful! Thank you!

Relaxing and refreshing day at a private oasis. Excellent facilities, food and internet. Very spacious room for everyone to grab a spot near the pools. Excellent staff. Breathtaking views.

Nice location. Natural thermal Park with over 20 pools. The children area is too small, my son of 9, had practically one pool to swim, the other 2 were for younger children. Beautiful beach, good food at the restaurant and cafeteria.

Poseidon Thermal park has been on my bucket list forever as well as Ischia. Now I have finally completed my bucket list and have enjoyed the pleasure of immersing myself in the health springs. Poseidon comes highly recommended by many people, male and female. This second visit I am including a facial therapy, the line correction, which I am really excited about! Also I have noted some simple tips from your brochure from 1 to 9 which I will be doing. I have been experiencing knee pain of late and hope the thermal waters may give me some pain relief including some long lasting benefits

Thoroughly enjoyed our day here, even though the weather was a bit cloudy, there is much to entertain with the different pools and water experiences. I particularly enjoyed the hot-cold pool and the chair where you are pummelled by hot water, very good for aches and pains and circulation. The gardens are very attractive and clean and pleasant. There are good changing facilities and lockers big enough for hand luggage, included in the entry. The cafe serves a very decent lunch at reasonable price and the indoor pool would be great as the weather gets cooler. You have to wear a bathing cap in the pools. What made it very good for us was that it was easily accessible by bus from Forio where we were staying.
