Estimated Times to Run







Once you've parked, continue up the gravel road. Graham's Bush signage should be clear. There is a large gate at the end of the road. Climb the steps to the left, and then continue a short distance before veering left onto the track, and then it's a short jog before reaching a small gate and the start of the track.

This beautiful reserve features a plethora of korimako, which can make for a very musical run. The track is close to running water which is crossed at points over short bridges. Expect some slippery rocks and mud year round, but especially after recent rainfall. Some pockets of the track are nestled into a wee nook and tend to stay wet. Once you're at the top you have options! You can take the track back the way you came, or you can make your way back to the Bethune's Gully track and make your way down there and back (if you're feeling like a double climb!) - otherwise, take some time to enjoy the scenery and some of the different sights such as the Organ Pipes and Butter's Peak.

This trail includes the peak Mount Cargill.

Grahams Bush Reserve was originally the site of sawmills and brick kilns operated by David Bethune in the 1880s, and became city council property in 1955. Mt Cargill rewards all climbers with a stunning panorama of Dunedin and the Otago Harbour. The Organ Pipes are close by, which are unique volcanic rock formations.

If you know of any public toilets near the trail start or on the route, please login and then let us know so we can update this section.

Plenty of on street parking near the end of Hall Rd. Don't drive up the gravel road as there's no parking and turning can be tricky.

The stream meets the track near the start of the track. Unsure if the water is drinkable.

Muddy and slippery rocks after rain. Exposed to cold winds at the summit.

Keep an eye out for livestock at the beginning of the track which rarely wander down from a neighbouring private driveway.

Sandra is just upset he hasn't qualified for Crush the Cargill.

Tough and quite technical in places. Great views at the top

A bit steeper and more technical than the climb from Bethune’s Gully but the same beautiful views from the top. And a tough climb up is always rewarded with a fun descent!

The real Crush the Cargill - don't listen to the propaganda spewed from Bethune's Gully!
