From the escalator at Robinson go East along Robinson Road, staying on the north side of the road. Go past Bishop Lei hotel, keep going and keep left. Eventually you reach the traffic light junction at the top corner of the botanical gardens. Go diagonally across the junction and then carry on now on the right side of the road past #1 Robinson Road. Follow the pavement (sidewalk) round the big junction with flyovers (at one point the pavement goes up a few steps then back down). Continue straightforward into what becomes Magazine Gap Road, crossing one estate entrance and one road that both go off to the right. Immediately after the second road off to the right there is a small crossing point on Magazine Gap Road. cross here and continue on the left side of the road past the Mothers' Choice nursery. Bowen Road then forks off to the left in a few yards. It starts as a one-way road, and then after passing under the peak tram you carry straight on where it is now a "pedestrians have priority" road although some cars still go down to access properties there. After a bit further it becomes fully pedestrianised. There are distance markers every 500m along the road from the junction with Magazine Gap Road.
