This place has 16 pools with different temperatures. It also has a private access to the beach . You must go to Fiorno ( 2nd Ferry exit). It is an amazing place in Ischia Island.

A big termal park with a lot of pools. You will pay 42 euros for a whole day. It is included acces to all spaces and to the beach.

Fresh and beautiful! Wonderful place to enjoy different thermal pools and natures together. We were totally relax over here. No doubt why here is always so popular no matter for tourists or locals. Visitors can spend a whole day or half day long over here. Price is fair, and Information can be found in the Homepage. Unfortunately, the most important downside is easily found that the dressing rooms and showering places are both so few to serve the massive guests at times. Secondly, it's not convenient for those guests who want to rent towels or bathrobes have to walk a long way to the end of park to enable to reach the Rental counter! Wrong Design! Thirdly, the watch for customers can not work as a smart calculator. That's why we have to either carry our wallets or get back to our lockers to get cash to pay-off our spending. What a pity! Don't forget carry swimming cap with you, we paid 3 Euro for a little cap. Anyway after all we did had some fun over here.

Absolutely loved this place. One of the highlights on our trip to the Amalfi Coast! We took a ferry from Sorrento. We took the bus there and had no issues using that for transportation. (It’s nice that Poseidon is the first/last stop on the No. 2 bus route so there’s a good chance you’ll get a seat on the bus.) There didn’t seem to be a ticket station close by to buy a return ticket (maybe there was and we just didn’t see it) but people paid the driver money for a ticket instead. You do need to bring more money than the costs you see online because you pay a bit extra as a deposit (for towels and admission) and get it back when you leave. For the swim cap, they cost 2.5 euro but you can also wear a baseball cap instead. For the towels, you can also bring your own towel so you don’t have to rent one. Surprisingly lockers were free. Lunch at the snack bar was great! They have desserts, sandwiches, fruit, and salad. Everything was tap-to-pay so we used my phone to pay versus having to get cash out of our lockers. The pools were super relaxing and not that crowded. (We visited mid-October.) Really nice that there was a lot of natural shade so I didn’t feel the need to put on tons of sunblock. The beaches, while we didn’t get in, looked lovely and much bigger than the Positano/Sorrento beaches. Will definitely be back!

Awesome! What an awesome way to allow natures way of healing and relaxing. The many pools, saunas and relaxing areas were awesome. An entire day of utilizing the hot and cold waters and spas to relax, naturally began to heal muscle aches and pains. The cafe within was a very good place to stop at and had great options.

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.

Man, what a cool spot! Poseidon is a traditional bath house, and a great day activity on ischia. The property is absolutely gorgeous and the baths are plentiful. I highly recommend.

We visited Poseidon terme... It was very lovely. I found a pool that was a very comfortable temperature for me and I lounged around for a few hours. I will definitely let my friends know if they plan on visiting Ischia in the future.
