Jardine’s Lookout and Mount Butler
Info from Hong Kong’s Great Outdoors
So near the city, yet so splendidly removed from it, these two hills afford panoramic views across the city and harbour to the north, and hills and bays of Hong Kong Island to the south. They lie along the Hong Kong Trail, which makes for a great walk from Parkview, up and over the hills, then down past the Tai Tam reservoirs.
Bus 6 or 61 from Exchange Square Terminus, Central, to Wong Nai Chung Gap, then walk up to Parkview entrance, opposite which is the trail up Jardine’s Lookout.
