Pak Nai (Chinese: 白泥) is a wetland area, partly mud-bank, surrounded by mountain ranges, in the Yuen Long District of Hong Kong facing Deep Bay (aka. Shenzhen Bay). Pak Nai makes up the coastline as Sheung Pak Nai (上白泥) and Ha Pak Nai (下白泥) geographically.
Pak Nai is famous for its ecosystem which comes with rich biodiversity, with rare species found offshore. In recent years, the public has paid concern to a controversial development proposal, which eventually was dropped under objections.
Besides its rich ecosystem, Pak Nai is known for its sunset views and historically-significant sites dating back to a couple thousand years ago.
Ha Pak Nai’s 6-kilometer-long (3.7 mi) shoreline is where mangroves, wetland and mud-bank are found. The mangroves in Ha Pak Nai habour various species and is highly conserved by environmentalists. The rich biodiversity of this area has prompted the government to designate it a Site of Special Scientific Interest (SSSI). Ha Pak Nai used to be an oyster bed, thus, there is still remains of oyster shells all over the mud flat.
Some species of crabs such as Perisesarma bidens, Ilyoplax tansuiensis, Uca arcuata and Sesarma sinensis are commonly found in the offshore mud flat.
Among all crabs found in the Ha Pak Nai area, the horseshoe crab is one of the most highly conserved species. Horseshoe crabs originate from 450 million years ago and are called “living fossils”. Because of the copper in their blood, which can be extracted to be applied in detecting bacteria, horseshoe crabs are highly valued in medicine.
Ha Pak Nai (“Ha” means “lower”) is known as one of the best places for viewing sunset in Hong Kong, making it a beloved place of many photographers, tourists and dating couples. The best sunset-viewing spots are the shores along Ha Pak Nai and the junction of Deep Bay Road and Nim Wan Road. Nim Wan Road is a popular 5 km cycling route for locals.
I went there on July 12, 2021 with my Nikon F6, AIS24/2, AIS35/1.4, AFD80-200/2.8 and AIS500/8Reflex. The film used was Fujichrome RDPIII.
