Dagály thermal baths, Public bath complex in Pest district XIII, Hungary

Dagály thermal baths opened in 1948 on the Pest bank of the Danube at Vizafogó, north of the Árpád Bridge, and its original buildings were designed by Lajos Darvas. The site holds ten pools of different shapes, sizes, water composition and temperature, including a 50 m lap pool that operates year-round at 24–27 °C and a 25 m pool covered by a tent from 1 October to 30 April. Its water comes from an artesian well drilled in 1944 to 126 m depth, yielding 41.5 °C water.

The bath opened in 1948 as the Szabadság Strandfürdő on the left bank of the Danube at Vizafogó, next to the Árpád Bridge then under construction. Its water came from an artesian well drilled in 1944 to 126 m depth, yielding 41.5 °C water. In 1970 thermal water from the Széchenyi bath was piped in and the site gained medicinal-bath status; the 50 m pool dates from 1956. Closed from September 2016, it reopened on 18 August 2018 after reconstruction for the Duna Aréna.

The bath's name comes from Dagály utca, the street joining Népfürdő utca beside it, and locals had long used it before it became official. In the Kádár era, XIII-district residents joked about summer crowding by calling it "Néplavór". Its Béke spring drinking fountain, outside the bath grounds, runs all year during opening hours at 40 °C.

The complex operates throughout the day and welcomes visitors anytime, with multiple entry points across the grounds. Expect wet surfaces and wear comfortable footwear, especially when moving between different pool areas.

The wave pool and one thermal pool were demolished in 2015 to make way for the Duna Aréna, built as the main venue of the 2017 World Aquatics Championships. The baths reopened on 18 August 2018 with new 50 m and 25 m pools. The original artesian well is now called the Béke well.
