9.3 meters wide X 3.3 meters deep X 16 meters high. . . but given all the overhangs, corners, bulges, etc, there's enough here to keep anyone falling off. The routes are almost infinite, though they're not really marked, but as all the locals come out, they keep it interesting.
It's just behind Camp Caroll, the USA Militaary base in town, on the grounds of the Social Welfare Center-- see map under navigational photos.
Bathrooms, vending machines all near by. There's a swimming pool and fitness center on the grounds, too. Plenty of room for picnicking!
