New Zealand is littered with volcanoes; there are some still moderately active ones, and hiking trails are closed and opened in tune with activity. The Tongariro Crossing walk that I enjoyed back in 2008 was closed due to thermal activity, but is now reopened recently. In addition to above-ground visual evidence of thermal activity, there’s plenty of evidence of the hotbed below the top layer (see my recent post about the amazing Hot Water beach).
We ended up enjoying Orakei Korako which reminded me of the activity in Yellowstone National Park back in the States. There were bubbling mud pools, geysers that shot in the air, silica terraces, and all sorts of mineral activity producing different colors (reds from high iron, greens from high copper, I assume?).
After visiting the hot springs, we took a wild jetboat ride back up the river with NZ Riverjet; super fun!
(Full disclosure – this was a very different jetboat ride than I took down in Queenstown in 2008. That ride was much more ‘intense’ and adrenaline pumping due to the closeness of the sheer rock canyon walls (as my footage showed). This ride had more wildlife, information about the surrounding plants and birds, and more 360-degree turns.)
