Amazing sights await in this geothermal wonderland. We visited here after Wai-O-Taupo and while there a some similarities (including the smell of sulfur), it is worth a visit to round out your understanding of the areas geothermal past and present.
Surprisingly this one is a bit more expensive but it too has some interesting sights.  This region was formed relatively recently just in the late 1800s and has some fascinating sites.
There are several options for touring walk, walk plus boat ride, but on the advice of our private guide, Martin of Martin's Tours & Transfers, we just did the walk to bus stop 1 after seeing most of the notable sights-perfect for people with limited time.  Their is a set bus schedule so no need to walk back up, just catch a ride on the free bus. It was about 5 min up by bus from stop 1.
The walk is mostly downhill and partially shaded so even in midday it wasn't too bad.  It's still a good idea to have water and sun screen as the geothermal features crank up the temperature in the park.  This park feature some great colored pools, steaming cauldrons and amazing sites.
Definitely worth doing.
