Spectacular Experience. No worries for parking. Rent a shovel, go to beach with your loved one, you will know where to dig because you will see a spot where every one are digging!! Start digging preferably a bath size and then it fills up with water from underwater hot spring, enjoy, be careful though water can get very hot.
Nice beach and the view is awesome. Go there when tides are low. I would definitely say this is top 3-5 beach that you have to visit in New zealand.
