Armour Bay Beach is a park at 5 Armour Road, Parau, Waitakere City, holding a 4.4 rating from visitors.
Small harbour beaches tucked into rural bays like this one often double as informal boat launch spots as much as swimming or picnic areas, so it's worth checking for boat trailers and ramp activity before assuming the whole shoreline is free for a relaxed sit-down. Parking tends to be limited at these smaller, out-of-the-way beaches, so arriving outside peak weekend times usually means an easier visit. The surrounding banks and mud edges typical of harbour settings like this can also be soft or slippery, so decent footwear helps more than jandals if exploring beyond the immediate shoreline.
For those in the Parau area, Armour Bay Beach is a quiet, low-key local spot worth knowing about.
