Waterfall Gully is a pocket of native bush at 1535 Whangaparaoa Rd in Army Bay, Rodney, where a short walk through trees leads to a small waterfall; visitors give it a 4.9 rating from 77 reviews and describe a serene spot well worth the trip.
Small bush reserves like this reward good timing. Waterfalls rise and fall with the weather, so visiting a day or two after decent rain usually means a proper flow rather than a disappointing trickle. Quiet native tracks are also among the easiest places to see kererū and other bush birds — early morning, walking slowly and quietly, gives you the best chance. Facilities at reserves this size are often basic or absent, so it pays to check the council's park pages before setting out, wear shoes that can cope with mud, and carry out whatever you carry in.
Tucked near the tip of the Whangaparaoa Peninsula, it's an easy detour that pairs nicely with a visit to Army Bay's beach.
