The line from the city commenced with a loop at the corner of Erskine and Day Sts near Wynyard Station. It then proceeded south down Day St before turning left into King St passing through Queen's Square at St James Station. It then made a right hand turn into College St, and headed south before turning left into Boomerang St. The line then continued left into William St, through King's Cross and then along Bayswater Rd and into New South Head Rd at Rushcutters Bay. The line then followed the course of New and Old South Head Road before turning right into Gap Park. After turning right into Gap Park a single track passed through narrow rock cuttings, low cliffs and rugged back-drops, turning its way down to the terminus at Watsons Bay.
The line had its own depot and city terminus and operated independently, although it was connected to the main Sydney tram network. In 1949, the line from Rose Bay to Watsons Bay closed, but reopened in 1950 due to public protest. In 1950, the line down King St to Erskine St closed and a new terminus constructed at Queens Square. The remainder of the line closed in 1960, the tracks were removed and in 1964 the Council re-vegetated the area around the former tramway cutting in gap park with the object of restoring the area.
When walking up the steps to The Gap at Watsons Bay, there is flat ground in between two sets of steps. This continues for a fair way in both directions, and is the old tram right of way.
The present-day route of buses 324 and L24 follow the route of the former tram line as far as the point where the tramway turned off Old South Head Road into Gap Park. The bus and tram routes meet again near the terminus in Military Rd.
