The ocean beach at Mangawhai Heads is a long, gentle curve of pale sand that runs north from the harbour entrance for several kilometres. The sand is soft, the dunes behind it are covered in pohutukawa and marram grass, and the water on a calm day is the milky turquoise that you get all along this stretch of the Northland coast.
It is patrolled by surf lifesavers in summer, and the flagged area at the southern end is the only place locals will swim near the harbour mouth — the rip through the channel is genuinely dangerous. North of the patrolled zone the beach is usually almost empty even on hot weekends. Bodyboards work well in the shore break, and the sandbar surf can be fun for beginners when there is a small swell from the east.
