About Piroa Falls

Piroa Falls lies within the Waipū Gorge Scenic Reserve on the Ahuroa River. The falls drop approximately 20 metres over a tiered basalt face into a pool that forms part of a popular swimming hole. The short track provides an accessible introduction to the native bush and gorge environment of the Brynderwyn Hills area.

The reserve is signposted from State Highway 1. From the car park, the formed track descends briefly through bush with a number of steps before crossing the river.

The concrete bridge carries the engraving “Rotary 1983”, commemorating work by the Maungaturoto Rotary Club. A minute or two beyond the bridge, visitors reach the base of the falls where the full height is visible against the bush-covered gorge walls.

Conditions can change with weather. The track surface may be slippery or muddy after rain, and the bridge crossing is unsafe during floods. Appropriate footwear with good grip is recommended, and visitors should avoid the river when levels are high.

The Piroa Falls Walking Track

The Piroa Falls Track is one of the shortest and easiest Department of Conservation walks in the Northland region. At roughly 200 metres one way, it suits families, those with limited time, or travellers seeking a quick nature stop. The path is well-formed but includes steps and a brief descent into the gorge.

After crossing the river bridge, the track continues a short distance to the falls viewpoint. Total time on the track is typically under 10 minutes each way for most walkers. The route offers a straightforward bush experience with minimal elevation gain.

Because the track is short and close to the main highway, it works well as part of a longer driving day through Northland. It also serves as an accessible option within the broader network of walking tracks around Whangārei and the Brynderwyn Hills.

Swimming at Piroa Falls

A swimming hole on the Ahuroa River below the falls provides a calm spot for a dip when water levels and conditions permit. The pool is popular during summer months for cooling off after the short walk. Water quality is monitored through regional programmes, and conditions can vary with rainfall and season.

Visitors are advised to exercise caution around slippery rocks near the water’s edge. The site is not patrolled, and river levels can rise quickly after rain. Checking current conditions before visiting is recommended for safety.

Getting There and Access

Piroa Falls is approximately 50 km south of Whangārei, a drive of about 45 minutes along State Highway 1.

Turn off at the signposted junction at the foot of the Brynderwyn Hills and follow Waipū Gorge Road for about 6 km to the car park. The final section is a narrow unsealed road with limited parking, so drivers should proceed with care.

The reserve is well signed from the highway, making it easy to locate as a convenient stop between Whangārei and Auckland. No entry fees apply, and the site is open year-round subject to weather and track conditions.
