High West, Mountain summit at 494 meters in Hong Kong Island.

High West is a mountain summit at 494 meters on Hong Kong Island located between Central and Western and Southern Districts. The peak offers views across to Tai Mo Shan, Castle Peak, and Lamma Island.

High West's north slope is where Harlech, Hatton and Lugard Roads meet, the start of the renovated summit trail. The mountain's south face, a near-bare cliff above the treeline, became a rock-climbing site. On its northwest slope, a World War II machine-gun pillbox was later topped by the Lung Fu Shan Viewing Platform, built by 2002.

The peak is also called Mo Tin Ling, "Sky-reaching Ridge", paired by name with nearby Mount Davis. Its Chinese name, Sai Ko Shan, sets it opposite Victoria Peak as the "west high mountain". The 2004 viewing platform and trigonometrical station at the top are the usual goal of walkers.

There are no roads or cable cars to the summit. The concrete path starts at the southern end of the High West picnic area, at the junction of Harlech, Lugard and Hatton Roads; standing on Harlech Road facing the area, the entrance is at its far left and is not obvious. Two rough trails also climb from the middle of the picnic area and above the High West tea garden retaining wall, both marked as unmaintained and closed.

The south face near the summit is a near-vertical cliff of bare rock where almost nothing grows, which is why it serves as a climbing site. The two rough paths up from the Lung Fu Shan picnic area 2 are marked "no through road" and "steep slope, do not climb" and are shown on maps as unmaintained.
