If there is a place to learn all about the flora and the history of Hong Kong, it has to be its countryside. Section 4 of the Hong Kong Trail starts at Lady Clementi’s Ride, which was named after the wife of the 17^th Governor of Hong Kong Sir Cecil Clementi. Traversing Aberdeen Reservoirs, the tree-shaded path is home to a great many species of insects and birds. If you walk on to Wan Chai Gap and cross the two delicate English bridges there, you will see native tree species like Ivy Tree, Turn-in-the-wind, Reevesia, and Incense Tree. Incense Tree, which got its name because of its fragrant incense, was once a timber export so important that it is said to be the origin of Hong Kong’s name. Blessed with abundant water resources, the mature secondary forests and Aberdeen Reservoirs house different species of birds, such as the whistling thrush, the Chinese hwamei, the greater necklaced laughingthrush, and the fork-tailed sunbird. The route comes to an end at Wong Nai Chung Gap. Surviving war relics can be found here in this important battlefield of the Second World War.
