Prizen is a town in Kosovo.
North towards Pristina
Just find NATO st in the north part of the city. Walk until you see KFOR military base and you can start there. It's pretty easy to get a lift directly to Pristina.
Southwest towards Albania
From the centre of Prizren, walk west on the big road called Remzi Ademaj. Continue west until you're out of the centre (it is not far) and see a gas station. From here, you can thumb and people will quickly stop for you. Watch out, however, for people that actually want money.
