Y-40: surface area of 21x18m, its maximum depth is 40m with various intermediary depths and caves for technical activities. The swimming pool contains 4300mc of thermal water kept at a temperature of between 32-34°C so you can swim and dive with your normal swimsuite. 


365 days to build the world's deepest pool

Y-40 is designed and built by architect Emanuele Boaretto, with the support of “Boaretto Group Hotel & Resort”.

You can find the new Y-40 swimming pool in the park of the Hotel Terme Millepini, a four-star hotel with thermal swimming pools and spa, wellness centre and thermal treatments.

The hotel is also known for its famous restaurant and the striking environment of the Europe Hall, where great cultural and entertainment events and weddings are held.

In this pleasant context you will find the water activities of Y-40.
