Whangaimoana Beach is the east side of the beach in Palliser Bay, at the bottom of the North Island. Take Lake Ferry Road from Martinborough through the south Wairarapa past the small beach hamlet of Lake Ferry. Confusingly, Lake Onoke will be to your right and you will find yourself at the sand spit and beach near where Onoke flows into Cook Strait.
Alternatively, turn left from Lake Ferry Road onto Cape Palliser Road prior to Lake Ferry. Follow Cape Palliser Road for about 3 km then turn onto Whangimoana Beach Road.
The black sand was particularly dramatic on the cloudy day we visited, contrasting against the white skies and reflections in the water. Due to the strong currents, swimming is not advised in this area, but it is a beautiful spot to stop and picnic. It is also a popular spot for fishing.
