No climbing apart from indoorclimbing (more than 26 good big climbing-walls)...There is one very nice one called Monte Cervino, a kind of copy of the Matterhorn Mountain,..where you can climb outside (even multi-pitch) and inside...
Anyway, as said by other members,...you have the Apls about 7-8 hours with the car. Not so bad...one day driving and you have the place to be in front of your eyes!!
Good luck in the Netherlands,
