Closed for lambing 1st August - 1st October. Lake Wainamu is a good example of a dune-dammed lake, and is part of the Waitakere swamp area, which covers 80 hectares and is the largest coastal freshwater swamp on Auckland's mainland. The walkway crosses the Waitakere River by footbridge and rises over a graded section nicknamed the Old Burma Road. The track then follows the clifftop, with superb views of lagoons, dunes, and West Coast surf. O'Neill Bay, the first bay passed, is a classic west coast beach set in a former andesitic volcanic crater.
Gannets diving offshore for fish are a frequent sight.
The track exits the coastal cliffs through a farm valley at Constable Road. A 500 metre walk along Constable Road brings you to the Goldie Bush track entrance. The walkway then divides. The alternative left track is a longer, more difficult route following the Mokoroa Stream. A high bluff gives splendid views of the Mokoroa Waterfall.
