Begin at the trailhead at the end of the gravel road in Orton Bradley Park. The trail follows a stream through an impressive forest of Beech, Kauri, Eucalyptus and Cypress. The trail eventually emerges from the forest and begins climbing through pastures populated by sheep and cows.

Follow the trail marking poles past the Mt Herbert Shelter to the broad summit. Summit views stretch out to the Port Hills, Banks Peninsula, Lyttleton Harbour and the South Pacific Ocean. From here you can either return the way you came or descend the Mt. Herbert Walkway via the North Ridge back to Diamond Harbour and then walk the main road about 4km back to your car.
