We like to hike from the South Gate to Hang Hau and back. It’s good exercise, and on some points on the trail there are nice views looking east to Tseung Kwan O and even Sau Mau Ping. Sunset can be quite nice. The full HKUST South Gate to Hang Hau gallery is available my photo site. When I am on this trail, I like to take pictures of the tree leaves silhouetted against light, especially just before sunset.
