Another Duck conveniently alongside ours on the Blue Lake.
Our driver gave an excellent commentary about the volcanic nature of the countryside and the fact that we were actually inside a huge crater!
The next morning we went to the Redwood forest and walked the treewalk high in the trees. We were fortunate to be there about 9am before it got very crowded. This meant we had a leisurely contemplative walk with time to stop at the platforms (22 of them) and read information boards. It is beautifully constructed without harming any trees.
Throughout the surrounding forest are artistically designed lights which at night would illuminate the whole path. Next time we'd definitely do a night walk. But we were warned that it is very busy at night so walking all the swing bridges with lots of others would be a different experience.
