Belgrade is the capital city of Serbia and Montenegro.
Belgrade lies where the rivers Sava and the Danube meet. Passenger ships enable you to reach every place along the Danube in a very convenient and meditative manner with many fascinating attractions along it, but it is a quite slow and rather expensive way of traveling.
Belgrade has busses and streetcars.
The Youth Hostel is very popular for travellers. It is huge, very sociable, and offers good rates.
Take care: A red traffic light is handled by car-drivers kind of a recommendation only. As long as you do not step on the street, no car will halt or even drive slower only.
