Hūnua Cossey Dam Track

Park closed for pest control from 5pm Wednesday 15 October 2025 until further notice

We have closed Hūnua Ranges Regional Park for extensive pest animal control operations. You should not enter the park as there is a risk to people and pets from this operation.

We are clearing the tracks and roads of 1080 bait so it is safe to visit again. We will let you know when the park is ready to reopen.

Visit How we protect the Hunua Ranges from pests to learn more about the pest control process and view maps of the area.

Visit Our Auckland for an update on the pest control operation.

About the path

Native forest, great views, waterfalls and giant kauri trees - this walk is a favourite with visitors to Hūnua Ranges Regional Park.

Start at the Hūnua Falls car park. Take a short detour (signposted from the carpark) to take in the famed Hūnua Falls before starting your walk.

Hike along the Cossey Gorge Track, a combination of gravel, boardwalk and bush tracks. To cross Cossey Creek, you will have to wade or walk across the rocks.

Admire the views when you reach the turnaround point at Cosseys Reservoir. Public toilets are available here.

Dogs are allowed on this track under control and on-leash, however must be kept away from the dam and water supply.

To prevent the spread of kauri dieback, large sections of the Hūnua Ranges Regional Park are now closed. Please stay on the walking tracks, and follow the instructions to clean your shoes before and after your visit.
