Robin's Nest, Mountain summit in North District, Hong Kong.

Robin's Nest is a mountain summit in North District that rises 492 meters above sea level and is accessible through natural hiking paths. The area features native vegetation and wildlife, along with the remains of border defense structures that once guarded the region.

The area served as a border defense zone starting in the mid-1900s, with fortifications built between 1949 and 1953 to guard the frontier. Before that, mining shaped the lower slopes when a lead operation employed hundreds of workers during the 1930s.

The Chinese name Hung Fa Leng (紅花嶺) means 'Red Flower Ridge', not 'Robin's Nest'; the hill was formerly called Ma Jeuk Leng (麻雀嶺). It lies in Robin's Nest Country Park, which was officially established on 1 March 2024 as Hong Kong's 25th country park, covering about 500 hectares of government land.

The walk to the summit takes about four to five hours from the nearest public transportation access point. The terrain is uneven and demands sturdy footwear, along with plenty of water and snacks for the full route.

Robin's Nest is the 55th tallest hill in Hong Kong, and its summit carries an auxiliary digital terrestrial television broadcast station serving Luk Keng, Yim Liu Ha, Shan Tsui, Kung Tei and Ping Che. The northern slope lies inside the Hong Kong border closed area.
