Budapest has an extensive and efficient public transport system so if you want to get from one point of the city to an other it’s worth using this way of travelling.
You have to buy your ticket before travelling in case of the underground you have to validate your ticket before getting on while in other cases you can do it on the vehicle. It’s worth getting a Budapest Card for tourists because it gives two or three days of free travel on public transports with discounted fees for a lot of museums and attractions.
Most transport runs until about 11:30 p. m. and the first starts about 5:00 a. m. However, for those who are going out in the evening there are night buses and trams so they can reach almost every part of Budapest.
Budapest has four underground lines that connects the important and central points of the city. There are also trams, buses and trolley buses that are circulating in the city.
Note that one of the most exciting way to reach the Castle District is via funicular. For those who wish to take a trip it is unomissible to use the rack railway circulating in the Buda mountains. Moreover you can use suburban train HÉV to reach some cities and settlements near Budapest. There are boat services as well on the Danube from the 1st July which has one stop on the Pest side of Arpad bridge.
