Jet Boating
New Zealand River Jet offers a Thermal Safari that allows you to visit thermal pools along with the exhilarating jet boat ride! If this doesn't make my girl giggle and laugh nothing will. I know her, she will be crazy will excitement and fear.
Another jet boating offering in the Taupo region is Hukafalls Jet, they offer a net package of jet boating and helicopter ride to unique areas like a volcanoes crater complete with lava flows. That sounds cool too! If price isn't a concern we may try this one.
Doesn't that look like fun!
