Tap Mun, officially known as Grass Island, is an island in the northeast of Hong Kong, situated between Tolo Channel and Mirs Bay, and surrounded by country parks. Its name was first recorded in “Grand record of Guangdong” written by the late Ming-period. The island has been used for centuries as a midway supply point on the sea route from Wai Chiu to Canton. The main feature of this Sitting-Out Area is a square pavilion located on a terrace of approximately 17 metres by 9.5 metres with stepped seating. The site is set against a woodland to the west and facing Mirs Bay to the east. The vast expanse of Mirs Bay is framed by pillars of the pavilion. With cattle freely grazing in the fields, waves lapping the cliffs and the sound of the waves echoing in the distance, the site offer its visitors an unique audio-visual experience. However, in recent years, the lack of camping facilities, freshwater resources and a lack of environmental awareness and responsibility on the part of visitors has led to increased desertification. The damage to the grasslands due to human activities has made the survival of the Tap Mun cattle difficult.
