Pools

You can enjoy seven pools filled with sea water, including two children’s pools, one swimming pool, a massage pool, and three pools with fun water effects. Access to the pools is free for St. Bernardin Resort Portorož hotel guests.

Children's entertainment

Sea Waterpark Termaris offers a lot of fun for children as well. In addition to seven pools, in which even the youngest of guests can splash around completely carefree, there are other children's facilities available, including a water cannon, a waterfall, a raging river, and whirlpools, as well as four waterslides for even more water fun.

Young sea

In Sea Waterpark Termaris, the pools are filled with the so-called "young sea", which is sea water enriched with minerals originating from various tributaries. The experience of bathing in our pools is as marine as it gets! The young sea has even more minerals than normal sea water, and has a beneficial effect on our body and well-being. Among these minerals are iodine, potassium, calcium, bromine, selenium, and magnesium.

Open sea view

How many times have you wanted to swim in the sea while visiting the coast, but the weather just was not playing along? At Sea Waterpark Termaris, you can forget about such problems, as the park is open every day of the year. The sea waterpark also offers an open view of Piran Bay, which will make you feel like you are swimming in the sea! This experience will be made even better by the heated sea water.
