📍 【Wong Nai Chung Gap (黃泥涌峽)】 is a natural mountain pass nestled right in the middle of Hong Kong Island, sitting snugly between Mount Nicholson and Jardine’s Lookout. Standing at about 250m above sea level, it has long served as a crucial gateway connecting the north and south sides of the island. Back in the day, five major roads intersected here, making it the must-pass bottleneck for anyone travelling between the Southern District and the north before the Aberdeen Tunnel opened. Winding streams flow through the gap, nurturing a rich, diverse ecosystem and carving out a unique valley landscape over time. —
