The southern-most island of Hong Kong, it is famous for its rock formations, such as the Buddha Hand Rock (佛手岩), the Coffin Rock (棺材石), and the Tortoise Climbing up the Mountain (靈龜上山). The Deserted Mansion of Family Mo, (巫氏廢宅), usually referred to as the "Haunted House", is a popular venue of "adventure" for the young visitors. The island is also an ideal place for skywatch. Another explanation states that Po Toi looks like a floating platform (浮台) when viewed from a distance on sea. 蒲 is another character meaning "to float" in the local dialect, thus giving the island its name.
