Very authentic place to swim. Always 36deg. You should bring your towel, swimsuit + bag for wet items. Too crowded in summer, very good in October-November or February-March
The pool itself is quite small, there are enough people there. In general, there is a lot to see in Herculaneum, and this place is the center of attraction for tourists. The water is really warm, as there are underground springs everywhere. The bottom of the pool is problematic. There are transverse obstacles in the form of columns about which you can bruise your knees or injure yourself. An open-air museum and salt terraces are within walking distance. Take water with you, it's not superfluous under the scorching sun. Enjoy your stay!
If you want to swim in the warm mineral water, then go to Cleopatra's pool. It's a bit far by bus from Kemer, but it's worth it. Plus unforgettable landscapes outside the window and a stop at the protected lake Salda with a white sand. Cleopatra's pool is the highlight and the perfect end to the evening. The water is 36 degrees and the taste of mineralization on the lips leaves an unforgettable feeling.
