Rotorua is the place to go to experience an abundance of activities from cultural to natural to adrenaline pumping - but the OGO is certainly one of the most unique ones on offer. OGO Rotorua is the home to the invention of rolling in an inflatable ball, just for the sheer fun of it. Pile into your own ball and race friends or hop in with up to three friends, and together roll down the 250m straight track or zig zag down the 350m sidewinder track, both of which will get you laughing in glee! To add to the fun, 40 liters of water is added into your ball, cool in summer and warm in winter, to amp up the slipping and sliding. This fun and safe activity is guaranteed fun for anyone age 6 or above and is certainly unique to New Zealand.
