Located in the Double Haven Geo-Area, Lai Chi Wo Nature Trail passes through an old Hakka village. It is the best place to get close to wildlife in Lai Chi Wo, and explore Hakka culture and history. As the largest Hakka village in North East New Territories in the 1950s and the 1960s, Lai Chi Wo had 211 village houses, all of which were built with nine narrow horizontal lanes and three vertical lanes for traditional Hakka fung shui reasons. Behind the village are the Fung Shui Woods, which are home to more than 100 species of trees and butterflies. Some trees are even rare in Hong Kong. Most of the houses were left to stand derelict, but the ecology and the geology there have drawn many tourists, injecting life into the village again. The trail also features some unique-looking trees and a diverse collection of wildlife. For example, hikers will be greeted with Five-fingered Camphor and century-old Hollow Tree, Autumn Maple. At the entrance of the village, they will also be welcomed by White-flowered Derris, mangroves, mudskippers in mudflats, and Dwarf Eel Grass, the biggest seagrass bed recorded in the northeast waters of Hong Kong.
