Nicknamed the 'Little Guilin of Hong Kong', Double Haven (Yan Chau Tong) is a tranquil marine park of islets, sheltered bays and sea cliffs off Plover Cove's far north-eastern shore.

Part of the UNESCO Global Geopark, it is reached by weekend ferry from Ma Liu Shui or on foot from Wu Kau Tang, drifting past landmarks like Bluff Head and the Devil's Fist.
