Administratively, it is part of the Tai Po District.
There are about 100 people living on the island. There is one seafood restaurant and a number of small tea restaurants on the island, many of which are well known for 'ice-less' ice-cold milk tea and boiled squid dishes.
Some fishermen of Tap Mun make a living by selling their sun-dried catch. Sun-dried fish and shrimp are popular amongst local tourists.
The hilltop of Tap Mun is a popular camping site, renowned for the contrast in temperature and wind conditions between day and night. Temperatures drop and winds soar during the nighttime but die down as the day approaches, when the dawn marks the beginning of a temperature rise. It is also well-known for providing panoramic views of the surrounding seas, and so provides a brief escape away from the busy city life.
The very gentle slopes of the hilltops are a favourite amongst campers, although there is the danger of the bordering cliffs. Adventurous campers enjoy precarious hikes along the dirt paths very close the cliff edges.
However, hygiene-conscious campers tend to stay away from Tap Mun as the island is home to cattle, resulting in hilltops dotted with many piles of faeces.
