Waitākere Dam is a reservoir and walking destination in the Waitākere Ranges, Auckland. It has a 4.6 rating from 192 Google reviews. Its listing describes kauri trees, the dam wall and a waterfall, and visitors often mention the walk down to the dam and the valley views.
Walks around Waitākere reservoirs are usually cooler under the bush but can be exposed on the open sections, so bring sun protection and water. Reviewers say the track down to the dam is downhill, which means the walk back up takes longer. Toilets are near the dam, and there is limited shade on parts of the route. Kauri dieback is a real risk in these forests, so stay on the track and clean your boots before and after your walk, as the signs at the entrance ask.
For a bush walk to the dam and a view of the valley, this park is a good half-day outing from Auckland's west.
