end, Leith Valley Road becomes Malvern Street, the main route through Glenleith. Glenleith The main suburban area within the Leith valley is roughly split into two suburbs - Glenleith in the upper valley and Woodhaugh close to the valley's mouth. The two suburbs, and particularly Glenleith, were both heavily industrialised during the early years of Dunedin, with the power of the Leith being harnessed for sawmills from 1850 and for flour mills shortly thereafter. The first commercial paper mill in New Zealand was located in the valley, the last overgrown remains of which can still be seen close to a walking track. The main road through Glenleith is Malvern Street, which runs from the Leith Valley Road in the upper valley to meet with Duke Street in Woodhaugh. Most of Glenleith's residences are located either on this street or around Fulton Road, a steep street which rises from Malvern Street, passing through forestry plantations before joining the end of Wakari Road near Helensburgh. A third main road, Rockside Road, runs from Malvern Street close to the boundary between Glenleith and Woodhaugh, winding uphill through the same plantations before becoming Tanner Road and joining with Wakari Road. These plantations contain numerous walking tracks, and also contain the historically listed Ross Creek Reservoir, constructed in the late 1860s. The walking tracks circumnavigate the dam, as well as following the banks of the Ross Creek and School Creek, two small tributaries of the Leith. Another major walking track, the Pineapple Track, has its northeastern end close to Fulton Road. This track traverses Flagstaff, a hill which dominates the city's western skyline. Woodhaugh Woodhaugh is the suburban part of the Leith Valley which lies below the Rockside Road intersection. At its top, it houses numerous older stone buildings, many of them of some historical significance. Lower down, the suburb is dominated by Woodhaugh Gardens, a large area of parkland and trees that forms part of Dunedin's Town Belt. Once a quarry, this is one of the city's oldest parks, dating from 1895. The area around the park is known as Woodhaugh and is a popular area for student accommodation, as it is only 15 minute walk to the university and the centre of the city. Most of Woodhaugh's residential area lies on Malvern Street, on Woodhaugh Street, a crescent in the upper part of the suburb, or on the small number of short streets
