Tui Park Beach sits in Greenhithe on Auckland's upper harbour, a small neighbourhood beach that holds a 4.3 rating on Google. Beaches on the upper Waitematā are strongly tidal, so timing shapes the visit: at high tide the water comes up close and swimming is at its best, while low tide draws back to leave broad mudflats and channels. Because these upper-harbour inlets sit at the end of urban stormwater catchments, it is worth checking Auckland Council's Safeswim water-quality alerts before a swim, especially in the day or two after heavy rain. Shallows like these warm quickly and suit children, though supervision near moving water always matters. Early morning tends to be the calmest, clearest time before the breeze picks up. Tucked along Greenhithe's stretch of the upper harbour, Tui Park Beach is the sort of place where a swim, a walk and the tide times all become part of the daily routine.
