Te Whanganui-A-Hei Marine Reserve is on the Coromandel Peninsula in New Zealand covering an area of 840 hectares.Cathedral Cove is named after the cave located there, linking Mare's Leg Cove to Cathedral Cove. Gemstone Bay and Stingray Bay are also located within the reserve. A walking track exists from the northern end of Hahei Beach, and it is also possible to walk from the local authority car park at the top of the headland between Hahei and Gemstone Bay. The area is very popular with tourists, and receives around 150,000 visitors per year.Boat and kayaking tours come from Whitianga in the north and Hahei in the south to visit the area. Both coves contain shapely natural rock stacks, Sphinx Rock in Mare's Leg Cove, and Te Hoho Rock in Cathedral Cove. Stingray Bay, and in particular Gemstone Bay, are popular snorkelling and diving areas, as marine life within the reserve boundaries is plentyful. In Gemstone Bay there is also a snorkel trail marked by the Department of Conservation.Both bays are also accessible by paths leading down from the main walking path to Cathedral Cove.The Māori name Te Whanganui-A-Hei refers to Hei, a tohunga from the Te Arawa waka.According to tradition, Hei chose the area around Mercury Bay as home for his tribe, proclaiming ownership by calling Motueka Island "Te Kuraetanga-o-taku-Ihu". It is said he made this claim near the site of the present-day of Hahei.The cave and beach was used as the tunnel through which the Pevensie children first re-enter Narnia in the movie version of The Chronicles of Narnia: Prince Caspian. More recently the cove was used as one of the locations in the music video for the song "Can't Hold Us" by Macklemore & Ryan Lewis featuring Ray Dalton.For an artists view of Cathedral Cove, visit the work of Kadira Jennings, who is currently engaged in a series of works inspired by this location.
