Letné kúpalisko Dudinka

Letné kúpalisko Dudinka is the open-air thermal bath of the Kúpele Dudince spa company in Dudince, southern Slovakia. The operator says the bath is named after the water nymph to whom, according to a well-known legend, Dudince owes the healing power of its local spring, and that it underwent a complete reconstruction in 2007, after which it became a favourite with locals, spa guests and visitors from the surrounding area. The operator classes it as a summer thermal bath, with mineral water in the mineral pool.

The operator enumerates the pools in the grounds without giving a total. It lists a recreation pool 25 m long, 12.5 m wide and 1.30 m deep with water at 26–28 °C; a pool with water attractions, taking the run-out of the flume, a family slide and a water channel with jets, at 28 °C; a children's pool no more than 0.4 m deep at 30 °C; and a seated mineral pool filled with Dudince healing water, 1.05–1.14 m deep at 33–34 °C. Across the site the water is given as 26–34 °C. The mineral pool is filled daily with Dudince mineral healing water, which the operator says acts favourably on disorders of the locomotor apparatus and the cardiovascular and nervous systems. It is a seated pool, meaning bathers should sit quietly rather than swim or stir the water; it is restricted to visitors aged fifteen and over, the maximum recommended stay is thirty minutes, people with heart conditions are told to take particular care, and jewellery is best removed beforehand because the mineral water can blacken it.

All the water attractions in the grounds – flume, slide, wild water and jets – are open to bathers, along with loungers, changing rooms and the children's zone; a stay in the mineral pool is limited to thirty minutes. Several stands and buffets sell refreshments, and free monitored parking lies about 150 m from the grounds. There are also sun umbrellas and lockers in the changing rooms.

The season runs from June to September, but the opening hours also cover May. Hours are: in June, Monday 11:00–18:00 and Tuesday to Thursday 09:00–18:00, with Friday to Sunday 09:00–19:00; in July and August, Monday 11:00–19:00, Tuesday to Thursday 09:00–19:00, and Friday to Sunday 09:00–20:00; in May and September, Monday 11:00–17:00 and Tuesday to Sunday 10:00–17:00.
