The Hunua Ranges cover about 400 square kilometres along the south eastern side of the Auckland region. Most of the area lies within the Waharau Regional Park, preserved for public recreation and water catchment. The park contains more than 450 species of native plants.
Hiking tracks in the park pass through dense native forests to high ridge lines that offer long range views to the city or the Firth of Thames. One of the popular shorter walks is to the impressive Hunua Falls. Swimming holes in the numerous streams and rivers offer a refreshing break on a more challenging hike
