The absolutely best viewpoint in Kosovo! The full view of Prizren and the the mountain in the background together seems magical after witnessing it in person.
It's actually just a 20 minute hike to get up there via Prizren old town. However, the path towards it is very steep. The views along the way up is also amazing!
The entrance into the fortress is free. It's grounds are also quite well-maintained, relatively clean, and have some basic facilities. Definitely a must do in Prizren!
