As a high-density compact city, Hong Kong carries the baggage of this, with a chronic shortage of easily accessible urban public open spaces. On the one hand, it leaves the stressful urban localities with no place for instant contact with nature; on the other hand, with a lasting impression of a ‘shopping paradise’ to the tourists, the micro-regeneration of urban public open spaces inevitably becomes tailored to the needs of shopping ‘pilgrims’. Such changes jeopardize the uniqueness and cultural identity of Hong Kong, and there is a crying need to preserve cultural heritage in the already very crowded urban public spaces. Along with the industrial restructuring and spatial regeneration strategies proposed in the newly released Greater Bay Area Development Plan, more public space is potentially relieved in the urban core of Hong Kong. The authors argue that this is a great opportunity for Hong Kong to create a truly integrated urban trail system, which not only connects the underprivileged high-density dwellers to the green and blue spaces, but also offers an interconnected experience of routes that celebrate the cultural authenticity of Hong Kong.
