One of the largest spa complexes in Europe, it was also the first thermal on the Pest side first built in 1913 and expanded in 1927. Located in the City Park, the Széchenyi Baths are the most popular with locals and travelers alike. From the outside, you'd never believe its enormity, but once inside it is humongous with a variety of 16 different pools, each with different water temperatures. One is a whirlpool that spins you around. Crowds of bathers, including many families and tourists, visit the palatial unisex outdoor swimming pool every month of the year, but due to its size, it never feels overcrowded. Turkish-style thermal baths are segregated and are located off to the sides of the pool. In warm weather, there is segregated nude sunbathing on the roof. If you like water, you will certainly want to spend the day here.
