There are few places in the world where thermal baths are as popular as in Budapest. There are many different types of baths in the city and it's up to you to choose where to enjoy a relaxing thermal bath and spa. If you really want to feel the spirit of local traditions, you should visit the Széchenyi Thermal Baths in winter. The Széchenyi complex was built in 1913 and worth seeing at the very least for its gorgeous neo-Baroque architecture and decoration.
Today it is comprised of 15 indoor and 3 outdoor pools, which vary in size, temperature, and mineral composition. You can spend your whole time in one bath or journey among the options available.
For the best experience from Széchenyi, schedule your thermal relaxation for a cold winter morning when most tourists are still sleeping and only locals come to play chess on floating tables in outdoor pools under the snowy sky.
