It is a U-shaped road that encircles the southern, western and eastern sides of the Happy Valley Racecourse.

It turns westward to Hong Kong Sanatorium & Hospital and then northwest to meet Morrison Hill Road and Queen's Road East and under the Wong Nai Chung Gap Flyover.

The western side of the road on the west of the valley forms part of the eastern limits of the City of Victoria.
