The walkway has been developing over the last few years and since I last walked it about two years ago, further work on it has progressed.
Future plans are to turn the huge hole into a freshwater swimming lake, but they have been saying that for years, so not sure when it will actually happen.
But for now, it is an education and a workout! I like to start the walk opposite the Information centre in Seddon Street and turn left at the battery to walk in a clockwise direction.
There are many places to stop and view the workings and machinery, plus read the information pinned onto the fence.
The walk is good on a cloudy cool day as in the middle of summer there is little shade. There are slight uphills, a small shelter-belt of native bush and open grasslands and waterways, that provide contrast.
After rain, there are wet parts so it is wise to wear waterproof footwear.
