A scenic 31km loop through Sai Kung's UNESCO Geopark and pristine beaches
The Third is a spectacular 31km loop through the heart of the Sai Kung Peninsula, tracing the Maclehose Trail past High Island Reservoir and its UNESCO Global Geopark coastline, over coastal hills with sweeping sea views, across remote beaches at Long Ke and Ham Tin, through ancient villages, and finishing with a panoramic climb to Tai Cham Koi (408m). A challenging but accessible introduction to the wider Hong Kong 100 course.
