Great views from the top to Shkoder and the lake, must see. No card accepted, but take euro (4 per adult, children free). No queues. It closes down at 7 pm! Parking is tricky, there are lots of private parking operators that will lure you in, just ignore. There is parking right at the gate, but it is usually busy. I could find some slot along the road and parked for free. The castle is large, many yards, various viewing points, so book at least an hour to walk around. There is a cafe and toilets. Also, you can visit a small museum (2 EUR).
