Hau Tong Kai is a very famous swimmable stream in Sai Kung Area. This stream meets Ko Tong Kau at Tai Tan. However, the portion that extend from Tai Tan (大灘) to Hoi Ha Road(海下路) is rather boring. It is advised to start the trip right at Hoi Ha Road.One of its swimming pool is easily acessible by even hiking novice. Although this stream is not very long, it packs with many sizable natural swimming pools. The stream is also wide, one does not have to struggle inside dense vegetation. In hot summer time, it is a nice place to visit. From hkadventurer.com
