Hong Kong Trail (Section 3) begins at Peel Rise. The initial section requires hiking uphill for about 600 m. After that, follow a “Hong Kong Trail” waymark onto an easy and level shaded path. Ferns and mosses line the way, along with native plants such as Champion's Rhododendron (Rhododendron championiae) and Hong Kong Gordonia (Polyspora axillaris). After weaving through the woods for about 1.5 km, you will reach a junction of trails toward Peel Rise and Aberdeen Reservoir Road. Continue toward Aberdeen Reservoir Road. Shortly after, you will catch glimpses of the dam of the Aberdeen Upper Reservoir through the trees. This concrete gravity dam, the valve house with a design influenced by Italianate Renaissance, and the stone bridge were declared monuments in 2009. The Aberdeen Reservoirs, consisting of the Upper Reservoir (constructed in 1931) and the Lower Reservoir (constructed in 1932), were constructed to increase water storage capacity for the western part of Hong Kong Island, addressing the issue of water shortage. This was the fourth and final reservoir built on Hong Kong Island, following the Pok Fu Lam Reservoir, Tai Tam Reservoirs and Wong Nai Chung Reservoir. Continue along the shaded path to a junction of trails toward Aberdeen Reservoir and Wan Chai Gap. Continue toward Wan Chai Gap for about 1 km to Aberdeen Reservoir Road, which marks the end of Hong Kong Trail (Section 3).
