Holleyweb Zorb Ball - It's an adventure that must be experienced to be believed. You'll literally roll over some of the most beautiful scenery in the world, all the while screaming and laughing like a child. Pioneered in Auckland, New Zealand, the Zorb places riders inside a giant flexible ball. A huge layer of compressed air separates the rider from the outer sphere, which rolls and bumps along courses of varying lengths for a variety of spills and thrills. On especially hot days, water can be poured inside, making for a splashy summer ride. A cutting-edge adventure, there are only a few places on earth where this ride can be experienced. Get in, strap in and roll all over the Rockies.
