Underworld Rafting on the South Islands West Coast is a magical journey of discovery in the unmodified Metro Cave System, with some of the best Glow Worm display on earth, deep in the karst and unspoiled wilderness of the Paparoa National Park. This adventure requires you to get in a wetsuit and float down an underground river system on a rubber tube.
Next, the Hagglund (an ex military vehicle) shows what 4×4 w off-roading is all about. Ride through assault courses that put it through its paces, climbing up steep muddy tracks that would have beaten a mountain goat. You stay dry and warm inside while the Hagglund gets down and dirty.
