As a visitor for one day: the best solution for parking your car is the large parking called "Polefermolen" (follow signs), which is right behind the hall. The other big lot on the other side of the road is also part of it. This is just an easy 100-150 meter walk, crossing the small river Geul over a small bridge. The small town of Valkenburg has decided that a parking fee is not only due during week-days (like in almost all other towns in the Netherlands) but also during the week-end! If you want to avoid a parking fine (Euro 50 appr.) or even a wheel-clamp (much more costly and inconvenient!) , please do not forget to fill up the parking meter properly!
If you stay overnight: Parking can be costly and can only be avoided by leaving your car at your hotel if you can in most cases the hotels do have their own parking areas. If not, in many cases they have permits for the larger parking lots nearby or for parking on the street in front. With our without charge... And if you stay in a hotel in walking distance (over 90%!) that is what you should do: leave the car there & walk.
DEALER INFO: for unloading and loading you may drive up to the main doors of the Polfermolen hall to do so, but AFTER DOING SO you will have to drive around the block to park your car as described above! If your hotel is on walking distance, you may choose to return the car to your hotel and leave it there after unloading, and bring it in again on departure.
The small parking lot next to the entrance of the Polfermolen is NOT to be used by visitors, dealers or collectors alike - unfortunately. Under no circumstances you can leave your car there. It is ONLY for residents of the area: parking fine Euro 50 appr.
