Walk to 'Kingdom Come'!!

Friend Roger invited Ken and myself to check out a walk from Heathcote Station to 'Kingdom Come' in the Heathcote National Park. Seems no-one has heard of this place--possibly because it sits on the edge of a military artillery training area!! The walk is interesting but quite challenging, at the further end. It also covers a tunnel entrance, which we explored, in the dark and wet, with bats.............

At the final site, there was a plaque on a tree, commemorating the place and the 'Knapsack' Club who may have first named the place?

We set off in good spirits...
