A walk along an old gold-mining water race in Kahurangi National Park, through forest from young beech and rimu to mature podocarps. The first section, across the Te Waikoropupū River to the old power station, is easy and suitable for all ages. Beyond the power station the track climbs for about 30 minutes to the race, and the website advises carrying small children in a backpack from there on, because a fall from the race and the water are dangerous. Following the race for about 30 minutes brings you to the weir, a picnic spot, and a 4WD access track makes a 50-minute loop back to the car park. The website says the lower sections of the climb have deteriorated, and that the birdlife is plentiful, with tui, bellbirds, weka and kereru. No dogs are allowed. The walk starts at the end of Pupu Valley Road, 9 km from Tākaka.
