Hidron

Hidron stands at Via di Gramignano snc, Campi Bisenzio 50013, in the province of Florence. It is a combined fitness, swimming and leisure complex rather than a thermal or mineral bath: the operator makes no claim of a spring, a thermal source or a water analysis, and publishes no water temperatures. Alongside the water park the site carries a gym, group classes, personal training, padel courts, a restaurant, a swimming school, a baby-swimming programme and medical consulting rooms.

The water plant is described as four indoor pools dedicated to sporting activity plus one outdoor pool available for the summer period. The indoor set consists of a Vasca Grande of 25 metres reaching 2 metres deep, used for free swimming, adult swimming school, competitive swimming, synchronised swimming and lifesaving; a Vasca Gym of 14 metres and 1.3 metres deep for water fitness, private lessons and Multisystemic Aquatic Therapy (TMA); a Vasca Piccola of 12 metres and 1.3 metres deep for Acqua Gym and Acqua Bike group courses, neonatal swimming and the children's swimming school; and a Vasca Ludica given over to recreation.

In its water-park guise the same halls read differently. The indoor park is presented as open all year, including through the winter season, with slides, pools, hydromassage and inflatables in the water; on winter Sundays half of the 25-metre pool is converted into an inflatable aquatic course. The Vasca Ludica carries hydromassage zones, vortices, seating and geysers, and from it guests reach what the operator calls the site's principal attraction: slides 12 metres high running a course of more than 60 metres. A dedicated baby area for ages 3 to 6 has shallow water, a small castle with a slide and water toys, with seating for parents around it.

The outdoor park opens only for the summer season. Its Vasca Grande is 50 metres long and up to 2 metres deep, mixing technical swimming and fitness use with aquatic inflatables; on Saturdays and Sundays that pool is given over exclusively to bathing. The Atollo is a semicircular pool with steps and a covered station with seating in the water where drinks can be taken. The Oasi is the sunbathing area laid out around the water park with stations of loungers and parasols that can be booked. A second baby area of shallow water for ages 3 to 6 has two mushroom fountains.

The operator lists the indoor water park as open on Sundays from 09:00 to 19:30. Tickets can be bought in advance through the operator's app or web shop.
