Shui Hau and Tong Fuk, on south coast of Lantau

A trip to the south Lantau coast at Shui Hau and nearby Tong Fuk makes a grand trip on a fine afternoon, including on a hot day summer day when a swim seems a good way of cooling off.
Cheung Chau (長洲) looks tiny on a map yet boasts plenty to see and do in a day.
Pui O in southeast Lantau has buffaloes, a good beach, and fine scenery.
Hong Kong is dotted with beaches, some of which are wonderful, and great to head to during the long hot summer.
