Park Wodny Olza

Park Wodny „Olza” is the water park inside Kompleks Zagroń at Istebna 1588, 43-470 Istebna, in the Silesian Beskids. The operator now calls it Park Wodny Istebna w Kompleksie Zagroń, and descriptions of the complex list Park Wodny „Olza” among its parts, alongside the Meridian spa centre; on site it is likely to be signposted as Park Wodny Istebna.

The water is not geothermal and not mineral. The operator publishes no borehole and no source temperature, only heated-water figures, and gives two: about 33–35 °C and about 34 °C. The operator presents the warm water as what makes the park comfortable whatever the season.

Guests use two zones, indoor and outdoor. The pool area carries geysers, a wild river, curtain waterfalls, whirlpool tubs and a children's paddling pool with a hippo figure and a mini slide, plus in-water massage loungers with jets aimed at feet, calves, thighs and back. The main ride is a 70 m water slide. The outdoor part is presented as a heated open-air zone with loungers, palms and natural stone, open to the Beskid ridges, with a water bar in the summer season; the operator calls the outdoor pools seasonal. The Medical SPA Zagroń Istebna area, separate from the pool hall, holds saunas, a brine graduation tower, an ionisation room and relaxation zones, and a salt cave; an earlier description of the complex lists a dry and a steam sauna, a salt-and-rock grotto and a climbing wall.

The water park is open daily 09:00–21:00, and the operator states explicitly that it is available to visitors from outside who are not hotel guests within those hours. The saunas run Monday to Friday 14:00–21:00 and Saturday and Sunday 10:00–21:00.
