A forest/rural section with a superb combination of medium speed narrow sweepers in the middle, great for practicing your skills ;-) watch out though as it is quite narrow.
Short but nice, you will not miss railway bridge which is the main attraction.
I drove it twice and I really regretted that I have left my bike at home. Very nice road. Quality of tarmac - superb. Loads of fast corners and nice corners.Pay attention do not cross to other side, Polish lorry drivers tend to cut cornets :-) I was able to drive there 160 km/h with my PT Cruiser. For sure I will try to ride my bike there.
Nice route with some local traffic. Road surface is poor, 80-100 max km/h. Some tricky junctions. The best comes at the end, that's the reason why I add this route. You ride down the hill in the forest suddenly forest ends and you do big wow :-) You can continue to go further to Teuven but road gets very narrow and twisty, watch out for tricky corners max 50-60 km/h From there you can go to Epen and ride back to Vaals. I hope you will enjoy it.
Some Nice Twisty up and down bits.
