Aria Te Uru is situated on the south side of the harbour, just at the mouth. The reserve has historical and cultural significance that can be observed on the Signal Station Track. The signal station was used between 1838 and 1951 when the harbour was an active port and ships needed to be safely guided through the sandy harbour. The 813-metre walking trail takes you along steep cliff tops and through commanding manuka forests before opening to a grassy lookout. From here you'll see postcard-perfect scenes of the harbour, coastlines, and sand dunes. Snap a classic Kiwi photo with a cabbage tree in the foreground before taking the Martin's Bay track to the harbour.
