Lamma Island is the third largest island in Hong Kong SAR. In contrast to Hong Kong Island and Kowloon, Lamma is peaceful and tranquil with an abundance of natural scenery. Buildings higher than three storeys are prohibited and there are no automobiles but diminutive fire trucks and ambulances, as well as distinctive open-back vehicles to transport construction materials. The community's only means of transport is either by foot or bicycle. Lamma provides an alternative to the hectic life in the city. As a result it has attracted a significant expatriate community to Lamma Island. It is also popular with younger people and a haven for artists and musicians.
