Bethell's Lagoon/ Te Hanga

Bethells Beach, New Zealand
Managed by Pulse Energy

Less than an hour’s drive from the centre of Auckland, this freshwater river lagoon sits beside Bethell’s Beach, and is a notable destination for fishing, cave exploration, and enjoying inspiring vistas. The black-sand beach area is also known by the Maori name ‘Te Henga’: so-called for the nearby dunes’ resemblance to an overturned canoe. Parking is available, though note that the Bethell’s is relatively remote and there are no facilities close by. Swimming is seasonally supervised and can be dangerous when venturing out of the lagoon and into the ocean, depending on the immediate weather and tides, so visitors should exercise caution. An opportunity for calmer, sheltered swimming is available at Wainamu, a lake only a few kilometers away.

Auckland Council has deemed this water body "high risk" due to ongoing water quality issues. It is recommended you do not swim or participate in other recreational water activities at this location.
