As most other cities in Europe Budapest also have their special city card, also known as a Budapest Card. This card gives you great deals on entrance fees, museums, free public transportation and discounts in restaurants and other places. In general we recommend the Budapest Card only to those who plan on using it a lot, which means that you are planing to visit lots of museums, go swim in the Szechenyi Thermal bath, visit attractions and sights and so on. If that is you, then the Budapest Card is good value for money.
Some people only order the Budapest Card to travel with the public transportation. If that is you then you should probably consider buying a simple transportation card for 24 hours, 72 hours or for one week instead.
