Jardine's Lookout, Mountain summit in Wan Chai District, Hong Kong, China

Jardine's Lookout is a 433-metre mountain in Wan Chai District on Hong Kong Island, east of Happy Valley and south of Causeway Bay. Its summit overlooks Victoria Harbour, and the slopes hold wartime pillboxes and trenches. The lower slopes between Wong Nai Chung Gap and Mount Butler form a residential area of thirteen roads named after colonial-era British figures.

Jardine's Lookout is named after William Jardine, founder of Jardine Matheson. In the sailing-ship era, a watch was kept here for the firm's clippers arriving from India and London; a whaleboat then collected the mail, and in 1866 this gave the company about an hour's warning of the collapse of Overend, Gurney and Company. The hill saw fighting during the Battle of Hong Kong, notably the Battle of Wong Nai Chung Gap, where Canadian Winnipeg Grenadiers and other Commonwealth troops defended the pass.

The name comes from the lookout William Jardine's firm kept here for its clippers; a whaleboat met each arriving ship to bring the mail ashore first. Today the Wilson Trail's second section and the Hong Kong Trail's fifth section cross the slope, and hikers often start near Hong Kong Parkview.

Visitors can reach Wong Nai Chung Gap by bus from Central or Admiralty, where the marked trail begins climbing toward the summit. The path is well-used and takes roughly an hour to complete on foot.

The name comes from the watch kept for Jardine Matheson's clippers: a lookout signalled incoming sails from India and London, and a fast whaleboat was sent to collect the firm's mail. In 1866 this head start let the company learn of the collapse of Overend, Gurney and Company about an hour before rivals and withdraw its bank balances first.
