The remains of an old power station and dam on Kawhatau Valley Road, just outside Mangaweka, reached by a short walk along a bush track. The road is at 5477 to 5479 Kawhatau Valley Road. Visitors describe the walk to the dam as about five minutes, with a nice view at the end. The path is narrow and can be slippery in places, so visitors should watch their footing. A rope near the dam lets people climb down to the river, and steps in the wall make that easier than it looks. The walkway is tight at the bridge but opens up straight after.
Reviews are mixed on caution and reward. One says the site is off the usual tourist route and well worth a look, but warns visitors to take care. Another says it is beautiful and a reminder of a time gone by, and that children find the remains fascinating, as they show how a dam and a power station work. Customers mention the bush track, the walk to the dam and the narrow path most often.
