Budapest is a truly child friendly travel destination with lots and lots of things to do with kids all over the city. There are almost 300 playgrounds, hundreds of kids events each month, superb children attractions and several bigger and smaller parks as well as outdoor pool complexes (some of the lidos have even thermal baths too).
Some of the regular kids things to do include visiting the Budapest Zoo, the Amusement Park, taking a fun ride on the Children’s Railway, playing and learning in the brainy Palace of Wonders at Millenaris Park, swimming and splashing in one of the best Budapest lidos or at AquaWorld water park, etc.
