Po Toi is an important birding hotspot in Hong Kong, with over 350 species recorded. However the numbers are declining like elsewhere in Hong Kong, the rather degraded environmental situation around the village being one of the factors. Po Toi is famous for its rock formations, such as the Buddha's Palm Cliff (), the Coffin Rock (), the Tortoise Rock () and the Monk Rock (). Ancient
rock carvings on the island, believed to date back to the
Bronze Age (around 1500–700 BC), were discovered in the 1960s. They have been listed as
declared monuments of Hong Kong since 1979. These may be viewed on a spur-track on the track that runs between the main harbour (Tai Wan), and the lighthouse. A
Tin Hau Temple is located on Po Toi, facing the bay of Tai Wan (). While its construction date is unknown, it is documented that the temple was renovated in 1893. Mo's Old House, or the "Deserted Mansion of Family Mo" (), usually referred to as the "Haunted House", is a popular venue of "adventure" for the young visitors. The existing house was built in the 1930s at Chang Shek Pai and has fallen into ruins. There is a lighthouse on Po Toi also known as
Nam Kok Tsui Lighthouse. ==Education==
