At first glance, Wairau Creek on the North Shore Coastal Walk / Te Araroa does not look enticing, especially at low tide. But you can easily wade across at low tide to continue around the rocky coast to nearby Castor Bay. If you cross with the tide in, watch out for boats, as the stream is the access to the Milford marina.
The northern side of the creek is also marked by the first of the North Shore cliffs that make up a significant portion of the coastline from this point on. Although they are not generally that high, they are quite spectacular with many instances of mature pohutukawa living life out on the edge.
If you walk into the adjacent park, you will see a footbridge that crosses the creek. The middle section swings up to give yachts access to the nearby marina. From the bridge it is a short walk up Beach Rd to Castor Bay.
