The dam itself is quite spectacular, much bigger than I'd expected. There is a noticeboard explaining some of the history of the dam, the tramline, and of course the vital pipeline that carries the water from the reservoir to the city.
The dam from the hill wot you walk down to get to it.
There are nice toilets (longdrops of course) and there's a little section of bush below the damn, with some beautiful tui - it's strange seeing them from above and noticing the beautiful teal plummage that we miss from our usual vantage point.
Then we walked back up the hill a little to the start of the Tramline Walk. It doesn't follow the tramline the whole way, as it is too dangerous near the dam itself due to a fragile cliff face. But it was a pleasant and interesting walk including:
Looking back along the track, and the pipeline
It marks the end of the Tramline track and from there you can either turn around and go back to the Dam track to get out, or head along the West Tunnel track. We chose the latter.
there was also impressive fungi.The West Tunnel track was pretty muddy in parts, and at one point, where we had to cross a stream, it was very difficult to work out where the track went next. There's evidence that the ARC is starting to put boardwalks through, but the work is only just begun and at the moment the track is quite a challenge in parts.
