Well the title says it all does it, here are the facts.....
Waimangu Volcanic Valley, near Rotorua, is the world’s youngest geothermal system, formed after Mount Tarawera erupted in 1886. The valley features spectacular volcanic craters, the vast Frying Pan Lake — the world’s largest hot spring — and the vivid blue Inferno Crater Lake. Visitors can enjoy peaceful self-guided walks (this is abolsutely true, they only let about 25 people into the park every hour, and the self guided walk from the entrance down to the lake takes about 2 and half hours so, yeah you don't see too many people) through native bush rich in geothermal activity and birdlife.
At the end you take a scenic boat cruise on Lake Rotomahana. (The boat size is what limits the number of people in the park, the lake itself is impressive with geothermal vents and alike, and some wildlife, but the walk is the real star of the show)
The Park is known for its rare ecosystem and striking landscapes, Waimangu really is like nothing you are likely to have seen before, and yeah it's expensive to get it, but then you feel like you are travelling through time to some pristine, never before seen land.
This is frying pan lake and it is a big and as weird as you think it is
The colours are insane in this park, I mean none of it makes any real sense in a 'things I've seen and understand sort of way.
This is the view up the valley there were people around when it erupted, because it was already a tourist attraction back in 1886, I can only imagine how terrifying it would have been, even from a distance.
