Gellert Spa Bath, Budapest (must see)

One of the best-known thermal baths in the world, Gellért Spa has come to define wellness culture in Budapest, helping shape they city’s global reputation for spa tourism for over a hundred years. Constructed in 1918, the complex is as much a feast for the eyes as it is a haven for relaxation. Its ostentatious Art Nouveau design shines through the grand vaulted glass roof and mosaic-covered interiors; meanwhile, while the outdoor pool was recently upgraded with a wave machine that kicks in every hour for a splash of fun.

Hungary’s bathing tradition goes back to the 16th century, when the Turks introduced spa culture during their occupation. But the Gellért thermal springs themselves were already known in the 1400s—revered by monks and hermits who believed the healing waters flowed from sacred depths beneath Buda’s hills. By the 19th century, Budapest’s mineral-rich baths had become wildly popular, drawing both locals and guests eager to experience the benefits of hydrotherapy. It was only fitting that such a growing demand would be met with a bathing facility that offered elegance along with wellness.

And that’s exactly what Gellért delivered—a lavish fusion of hotel and full-scale thermal spa. The architecture is dazzling—inside and out—with striking tiles and stained-glass windows greeting visitors right from the entrance. Once inside, one can enjoy a variety of pools, both indoor and outdoor, along with baths, saunas, a steam room, and a range of massage therapies. Even traditional Thai massage is on offer here, at rather accessible rates.

For those who’ve worked up an appetite, a charming garden café awaits outside, surrounded by blooming flowers and elegant sculptures—the perfect way to wrap up a rejuvenating visit.
