With its long stretch of mangrove beach, mudflats and calm, reflective waters, Ha Pak Nai is frequently touted as Hong Kong’s best sunset spot. Flanked by mountains on one side, and views of Deep Bay on the other, this area is known for its biodiversity and the six-kilometre coastal trail along the western, sea-facing wetland; it’s great for hiking, jogging or gentle cycling. And those cranes in the background? That’s the Mainland Chinese city of Shenzhen. Prepare to jostle with professional shutterbugs and amorous couples when trying to capture that perfect Instagram moment.
