Aquaréna

Aquaréna is an open-air water park at Mogyoród in Pest county, immediately beside the Hungaroring motor-racing circuit and about fifteen minutes from Budapest. The operator describes it as Hungary's largest entertainment water park and gives its area as 11.5 hectares. It is a summer attraction rather than a year-round bath: there is no covered hall, and the operator warns that in cool, windy or rainy weather the park may simply not open, advising visitors to check before travelling. A campsite on the grounds offers several kinds of accommodation, and the park also rents day beds, sun-lounger sets and canopies.

The operator states that Aquaréna stayed closed for the 2026 summer season and will next open in the summer of 2027; no reason and no more precise date are given.

Slides are the core of the offer, and the operator gives two counts for the same 1.5 kilometres of slide track: 28 different slide runs, and 23 slides, 17 for adults and 6 for children. Individual runs are described with figures: the Vakond (mole) slides are 130 metres long and pass underground, the Kalandcsúszdák (adventure slides) carry riders along runs of up to 120 metres into a pool 14 metres below, the Nagy csobbanás racing slide has six 60-metre lanes falling four storeys, and the Óriáskígyó (giant snake) is a 50-metre pair of intertwined tubes. Other named rides include Fekete lyuk, Repülőszőnyeg, Rafting, Szabadesés, Vadvízi folyó and UFO. A shoulder height of 120 cm is required for every slide outside the children's pool.

The still water is plain heated or ambient pool water; the operator claims no thermal, mineral or brine water, and no temperature is published for any basin. The operator names the pools individually instead of counting them: a 700-square-metre leisure pool with a current channel, bubble bath and rainforest cascade; a children's pool; a circular glass-mosaic jacuzzi; a diving pool 3.5 metres deep with rock ledges one to three metres high; a 300-metre Lazy River; and the Blue Cave, a lake-filled grotto reached from the Lazy River through a rock canyon.
