Cornwallis Beach is on the eastern side of the Karangahape Peninsula, Waitākere Ranges, Auckland. It is the best-known beach accessed from Huia Road. Take the signposted turnoff and then a second short road to the main parking area.
It is popular in summer with plenty of parking. There is a substantial grassy area behind the beach, framed by native regrowth and older pine trees, with a couple of bush walks. The walk along the beach to the Cornwallis Wharf is also interesting as the tide goes out, with colourful cliffs, a mix of back and orange sand, and rock pools.
