Situated in the valley behind the 300-year-old Hakka village of Fung Yuen sprawls the Fung Yuen Butterfly Reserve, a protected site that’s home to more than 200 species of butterflies, including the pretty Common Birdwing and White Dragontail varieties. As well as rare breeds of butterflies, you may also spot some unusual breeds of terns (seabirds). Visit on the last Sunday of each month for the Butterfly Festival — a selection of exhibitions and guided tours.
