One of the best european DZ's I've been or heard of. Very professional, friendly and helpfull staff (coaches, packers, manifest).
Relatively cheap if you include the jump altitude (4500-5000m), with great views,
good infrastructure - packing area, debriefing rooms, bunkhouse, showers, restaurant with excellent (and not expensive) food. Combine it with some
of the best load organizers and coaches, and what you get... A+ DZ.
They've got a nice coloring program at 'Kurupee': http://www.kurupee.com/secciones/products/products.html
