Closest in of all the Sai Kung islands, Sharp Islalnd - as its name suggests - runs north to south with two narrow points. Two kilometres long and half a kilometre wide, it rises to a 136 metre summit. Only two kilometres from Sai Kung town, this is the recreational focus of the nearby islands. There is a cobble beach at Kiu Tsui; and, at the opposite end of the island, Hap Mun has a crescent bay with a sandy beach. On weekends both places attract holiday makers, but during the weeks the island is little visited.最靠近岸邊的橋咀洲，英文名Sharp Island（意指尖銳的島）正好生動地把其形狀描述出來──南北伸展，兩端尖削。該島長2公里，闊半公里，最高點為136米的山頂，所在處僅距西貢市2公里，是附近島嶼的休閒活動集中地。橋咀有一卵石灘，彎月形的廈門灣沙灘則在島的另一端，兩者皆是周末度假者的勝地，平日卻鮮有遊人到訪。
