From the Wong Nai Chung Gap road.

I think that this must have been shortly before the bus turned to the south and grew level with the Happy Valley race course.  Stonecutters Island is just visible in the distance.  Following identification by Moddsey and E David of another view taken on the same bus ride, I am renaming this photogaph Stubbs Road view looking North.  No.

However, in order to show how accurate and helpful other readers can be, I have left this first paragraph in its incorrect form.  The bus was heading south along the Wong Nai Chung Gap road well south of the Happy Valley Race course, and the Tai Hang road is visible at the bottom left corner, with the Green Lane Service reservoir clearly identifiable in the centre of the photograph.
