Waimangu Volcanic Valley is the youngest geothermal system in the world. Tourists were flocking to the area before it was even formed, to see the Pink and White Terraces. Then, in 1886, Mount Tarawera erupted. Over a hundred people died, the Pink and White Terraces were destroyed, and Waimangu was born.
Pronounced with a silent ‘g’, Waimangu means ‘black water’. It was named for a geyser – the largest in the world at the time – whose water was dark with mud and debris. Unfortunately, this geyser was only active from 1900 to 1904, but it saw many tourists during that time. Four people died in 1903, when the geyser took them by surprise, and another two in 1917, when an eruption destroyed a nearby accommodation house.
The ruins of the accommodation house weren’t pulled down until 1970.
As far as I know, no tourists have died since, though various eruptions continue to shape and reshape the valley.
It’s quite expensive to visit Waimangu. My fiancé and I only did the self-guided walk and that was $42 each! It included a shuttle ride from the bottom of the track back up to the café/gift shop, but still… If you add the Lake Rotomahana boat cruise, it’s another $43 each. Lake Rotomahana is where the Pink and White Terraces were. There are a few bubbling hot springs and geysers along the shore that are inaccessible except by boat.
It turned out my fiancé and I couldn’t have done the cruise if we’d wanted to, as the boat’s engine had just given up the ghost. We got chatting to an employee about it as we were waiting for the shuttle. Apparently – and I apologise if I’m remembering this wrong – the boat had an ex-1950s double-decker bus engine, and, well, try finding a replacement one of those in New Zealand!
So, the walk. Upon leaving the visitor centre, we were confronted with this rather nice view…
… and it only got better from there. As we followed the gravel path down the valley, towards Lake Rotomahana, a smorgasbord of geothermal delights presented themselves. First came a lake half smothered with pinkish red algae so thick it looked like a rubber mat.
Then came a lake that appeared to shiver in the sunlight, but was actually bubbling with heat. Wisps of steam eddied over its surface like spirits performing a dance.
Then there was the stream, steaming away in full technicolour.
There were lots of other interesting geothermal features on the way to the lake, but the stream is what stood out to me.
It takes about two hours to get down to the lake, which is why it’s nice to be able to take the shuttle back. There’s a total of three shuttle stops along the walk, so you don’t have to do the full track. The best stuff’s in the first two-thirds, not counting the beautiful lake views. Take sturdy shoes, sun protection and a drink bottle.
So, I suppose the question is should you visit Waimangu Volcanic Valley over the many other geothermal sightseeing attractions available in and around Rotorua? If you’re short on time and/or money, no: there are places with more spectacular geothermal features than this. If you’ve already visited a few of those other places and are looking for something different, yes: it’s a lovely walk.
