There are many wonderful spas and thermal baths in Budapest, but the most beautiful one has to be the Géllert, attached to the hotel of the same name. Built in 1918 in Art-Nouveau, the main hall with glass roof and Roman-style columns is the most striking. Stick your head under one of the stone lions out of whose mouth water rushes out. There is a warmer thermal pool in the main hall, plus there is an outdoor wave pool and thermal pool, plus additional thermal baths as well. Bring your swimsuit, towel, cap, and pool shoes, and you can get a locker or cabinet to store your clothes as well. These items can be rented as well. You'll notice that the pros know exactly when the bubble jets turn on periodically because they always get the best places in the pools!

Directions: At the foot of the Szabadsag (Freedom) Bridge, you can take tram 18 or 19 there as well. The bath entrance is on the right side of the hotel.
