Hiking and River-treks
The island is carpeted by the hills, which in turn are bisected by number of seasonal rivers, creating several exquisite waterfalls and gorges. Hiking on these hills is organised by various groups. Walks along streams and falls are also organised. Lantau Island has an abundance of riverside walking. Violet Peak on the south of Hong Kong island is also known for river-trekking.
Diving and Snorekelling
Hong Kong is circled by sea. Rocky coasts provide home to exquisite range of marine fauna. More than 80 species of corals and over 300 species of reef fish have been found in the region. These circumstances make activities like diving and snorekelling very rewarding. However, underwater visibility in the coast depends on the wind and tide conditions. Several artificial reefs have also been created for the benefit of the travellers.
Hong Kong has number of country parks which can prove very intriguing for the lovers of avian life. In Hongkong, birding is best from early October to late April. Noteworthy places for birding activity in Hongkong are Mai Po Marshes Nature Reserve, Tai Po Kau Nature Reserve and Long Valley. Po Toi Island is a must-visit for any bird-watcher.
