Giardini Poseidon Terme

This place is absolutely beautiful and would highly recommend you do the entire day here. Even doing the Hot to cold spa baths and do the entire thing. Highly recommend so many times!!! The food was more like amusement park prices and the quality was fine. This review is more about the thermal park itself.

A beautiful island with thermal pools? Yes, it's amazing! We spent the day here enjoying the many relaxing and rejuvenating pools and sauna. We also really enjoyed the restaurant here for lunch.

Proof if any were needed of the geothermal activity in the Bay of Naples. Although children are not permitted to enter the main hot pools, there are pools where they can happily play if supervised by an adult so it isn't too restrictive. My wife had a great time in the hot pools and sauna while i looked after our little one. For us this was a great day out from Sorrento where we were staying and involved an enjoyable ferry trip from Sorrento harbour,

Such a beautiful park! My husband, 1.5 year old son, and I visited for the day. Kids aren’t allowed in the thermal park so we stayed by the kids pools and switched off enjoying the spas. Such a relaxing experience at a great value. We got lunch at the cafe as well. The pool areas were clean and spacious and everyone there was respectful. One of the highlights of our trip.

We went in September 2025 and the Giardini Poseidon Terme is one if the main reason we came to the island. This is Paradise on Earth! There is a large cafe where sweets are also offered, restaurants, it has it all, so you can just relax. I have to mention that I had some residual cough, but after I visited the cave sauna, it disappeared.

Great experience for a day. The entry is 50 € per person for the whole day. You can choose in any area a sunbed for the day. They have a bar open all day with drinks, desserts and sandwiches and a restaurant with food till 4pm I think. The pools are clean with hot water from 32 to 40°. It's worth the experience for a day if you stay 7 days on the island.

Super clean, nice and relaxing atmosphere. There are free lockers and many changing areas. Two restaurants for breakfast and lunch, not too many choices, but there are some still. You need a whole day to visit everything and enjoy the park’s diversity.

This is a large thermal bath complex with many pools and beautiful landscaping. The position, on a side of a hill all the way to the sea, with its own private beach, leads to breathtaking and mesmerizing views. This place is really a gem.

Words and pictures don't this place justice!!! This bath resort was spectacular, and I had such a relaxing experience here. There are over 20 thermal pools ranging in different temperatures, which all sit in a vast property that sits right on the beach and alongside a beautiful hill. There are two restaurants available to guests to choose from and enjoy, a boutique to shop at, and spa that offers services like massages, facials, etc. I got myself a massage and it was great. I wish I could have spent longer at the resort to be able to check out all the different pools. I definitely recommend this place to others who plans to visit the island of Ischia... the only downfall is getting to the island for those who are prone to motion sickness. It is a 50 minute boat ride from Naples.

What a great day! 38 euro might seem steep to get in but not when you can spend 10 hours there. You have access to the many pools and a private beach. It was worth every cent and we totally enjoyed our day. The property is well kept and really pretty with all the plants. Everything was very clean. Prices in the cafe were reasonable. Only 2.50 for cappuccino so they weren't trying to take advantage of you. You do need a bathing cap for the pools but they sell them for $2.50. We enjoyed our day and would highly recommend.

Incredible selection of thermal pools, natural sauna and next to a nice beach. Once you get over a fact, you have to wear a hat, it's enjoyable. It does cost 35 Euro pp plus 2.50 for the swimming hat if you don't have your own but in that you have a sunbed or chair with umbrella either by the sea or by the pools and there's plenty. Although it's full of people it's worthy seeing it. To avoid crowd on lunch time, wine bar on the hill by the caves for lunch is better and also it does have a better wives than main restaurant...

By far the best beach and best thermal springs in ischia. Great food too! It's a little pricey to get in for the day but definitely worth it! We went twice during our trip. Ask about multiple day passes if you're going to go more than once.

This seems to be a great thermal bath park with beach. However a bathing cap is required for the thermal bath and kids are not allowed in the baths. If you do not have a bathing cap - this is a waste of time. Therefore we spent most of the day at the sandy beach, which was wonderful. The park requires people to wear "watches" for check in to each bath or beach site - this seems a little over-kill. The food was average. Self-service is very busy and full of impatient people. In fact most of the clientele here seemed very unfriendly and not in a good mood. The restaurants were not fully staffed or resourced and the service was lazy and not customer-focused. The boutique was wonderful and British-staffed.
