The starting point of Hong Kong Trail (Section 5) is located near Wong Nai Chung Reservoir Park. Wong Nai Chung Reservoir was completed in 1899 and once served as a supplementary water source for the Tai Tam Group of Reservoirs, further expanding the facilities for storing water on Hong Kong Island. Since the 1980s, Wong Nai Chung Reservoir has no longer been used for storing drinking water and was converted into the current Wong Nai Chung Reservoir Park by the former Urban Council. Now open to the public, it is managed by the Leisure and Cultural Services Department. From the starting point, walk for about 550 m along Tai Tam Reservoir Road to the entrance of Wilson Trail and Hong Kong Trail. Climb the steps for about 200 m to the Osborn Memorial. It commemorates the Winnipeg Grenadiers’ defense of Mount Butler against the Japanese forces on 19 December 1941, highlighting Company Sergeant Major John Osborn, who sacrificed himself by shielding his comrades from a grenade and was posthumously awarded the Victoria Cross. Then, walk for about 1 km to the viewing point at Jardine’s Lookout, where you can gaze over Victoria Harbour. Continue along the winding path, from which you can overlook the former Mount Butler Quarry. After another 1 km, you will reach a junction of trails toward Siu Ma Shan and Quarry Gap (Tai Fung Au). Follow the directional sign for “Tai Fung Au” and walk for about 350 m to the Mount Butler Viewing Point, where you can enjoy panoramic views of Violet Hill, Tai Tam Upper Reservoir, and Tai Tam Tuk Reservoir. You can also take in distant views of the bustling commercial districts on both sides of Victoria Harbour. After a short rest, walk downhill for about 250 m to Quarry Gap, where you will reach the endpoint of Hong Kong Trail (Section 5).

To celebrate the 40th anniversary of the establishment of Hong Kong Trail, public can participate in the “Unlocking Hong Kong Trail” hiking challenge from now until 28th February, 2026. Participants can first register at the event website: www.unlockinghktrail.hk, then visit the eight sections of Hong Kong Trail. To “unlock” the checkpoints and collect e-badges, participants should scan the QR code at the checkpoints using smart phones and answer a question about the fun facts of Hong Kong Trail. Participants may be awarded a commemorative prize if they have completed all eight checkpoints during the event period.

_{To facilitate the public in planning their hikes, the geographical information of the route, including the route map, starting point, endpoint, and elevation chart, has been saved in a "GPX" file. The public can download hiking-related applications on their smartphones or smart watches, then click on the following "GPX" file to import the relevant information, which serves as an aid for hiking. Please note that downloading "GPX" files may increase data usage, and the functions and content display may vary depending on the device and application used.}
