Replying to Skiing in the netherlands

I am doing a semester abroad and the school I am going to is in Leiden in the Netherlands. I realize there are not mountains in the Netherlands so I plan on doing weekend trips to the alps however I have heard of indoor skiing facilities in the Netherlands that have parks. Are any of them near Leiden? I only want to know if they have a park because I don't really just want to make turns in a big fridge. +K for any help. Cheers
