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.
Several camping areas, equipped with the basic necessities, provide scenic accommodation. These are located either near the park entrances or deep within the forest on some of the longer trails. Bookings are required - contact the Auckland Regional Council.
Mountain bikers are welcomed in the ranges and some exciting trails have been built by biking enthusiasts working with the regional council.
Both the Mangatawhiri and the Mangatangi dams offer rainbow trout fishing along the face of the dams.
The Hunua Ranges are located around one hour's drive from the city centre.
