From the Pohokura Road entrance, the Bell Rock Loop Track climbs through a forest of gnarled broadleaf, horopito/pepperwood, fuchsia and mataī. The track emerges onto the range though a dense stand of mountain holly providing spectacular midsummer floral displays. Bell Rock is 40 minutes further along the left track.

The right track returns to Pohokura Road via a 4WD track and provides panoramic views, including the Mohaka valley to Te Kooti’s Lookout and further afield to Whirinaki Te Puaa-Tāne Conservation Park. Return via Pohokura Road.

Bell Rock has dangerous drop offs. Extreme care is required at all times, and extra caution in windy or wet weather. Always supervise children.

Boundary Stream Mainland Island is located approximately one hour's drive north of Napier. Follow State Highway 2 to Tūtira, turn left at Tutira onto Matahorua Road then left onto Pohokura Road.

The final 20 minutes of the drive is on an unsealed road. It is narrow, winding and steep in places. Stay left, keep headlights on, and drive to the conditions.

The car park is small and can fill up quickly, especially on summer and public holiday weekends. Do not block the road or farming access routes when parking. Be cautious of approaching traffic if walking down the road.

What to expect

• Unfenced steep drops
• Muddy and slippery track after rain
• Steep and strenuous in places
• Fully exposed to the weather on parts of the track

Predator control

• Boundary Stream Mainland Island has extensive predator control. This protects rare native birds like kiwi, kōkako and kākā. Do not disturb traps and bait stations.
• There is a network of predator traps throughout the area, marked by pink and blue triangles. Follow the orange triangles to stay on the walking track.

There are wasps and ongaonga (native stinging nettle) in this area. We recommend carrying allergy medication and avoiding touching the ongaonga.
