Follow the steps up from the far end of the Hok Tau dam, and the scenery changes again: now you’re climbing an earthen path up through tall forest. Gaps in the foliage allow you glimpses of the bulky mountain ridgelines that dominate this rugged yet luxuriantly green part of Hong Kong. Lau Shui Heung Reservoir is a place where joggers and families and Instagram enthusiasts go to enjoy open space and fresh air, and to appreciate the calming view: the reservoir is colloquially called ‘mirror of the sky’ for its deep, reflective waters. At different times of year, the changing leaves and blossoms of the forest create an ever-evolving diorama of water, nature and sky. It’s an idyllic setting where you have another chance to admire Hong Kong’s captivating diversity of dragonflies and damselflies, including the bright red-bodied Crimson Marsh Glider dragonfly and orange- or yellow-legged Yellow Featherlegs damselfly.
