I went to the Rotorua area again for some more fumarole action, this time to the Waimangu Volcanic Valley. My legs were still war wounded after the Alpine Crossing so the steep descents were painful. Waimangu has a very sweet pale blue lake (I'm quite into collecting lakes of different colours.) It also has a very good terrace part of which looks like a giant has been icing a cake. The earth itself bubbles and fumes and puffs here. Happily there was a bus which I caught back up the hill to save my lower limbs!
