Justifiably famous, Hot Water Beach is quite extraordinary. For two hours either side of low tide, you can access an area of sand in front of a rocky outcrop at the middle of the beach where hot water oozes up from beneath the surface. Bring a spade, dig a hole and, voila, you’ve got a personal spa pool. Surfers stop off before the main beach to access some decent breaks. The headland between the two beaches still has traces of a Ngāti Hei pā (fortified village).
