Little Oneroa Beach Reserve is a beach and reserve at Little Oneroa on Waiheke Island, with a 4.4 rating on Google. On the beaches around the Hauraki Gulf, timing is everything: the water is usually calmest in the morning before the summer sea breeze springs up, and swimming is best within a couple of hours of high tide. Low tide exposes sandflats and rocky ends, better for a wander and rock-pool fossicking than for swimming. New Zealand's sun burns quickly even under cloud, so pack shade and sunscreen, and after heavy rain it is worth checking water quality before heading in. Regulars tend to arrive early, carry what they need, and let the tide set the shape of the day. Tucked along Waiheke's coastline, Little Oneroa Beach Reserve is a well-liked spot for the unhurried kind of beach day the island does best.
