Local people have a very simple way of living.

There are some villages situated on the island.

Northern village is called Yung Shue Wan - the most populated area on Lamma Island. It’s main business - seafood restaurants, pubs, grocery stores and shops which sell oriental and Indian-style handicrafts, environmentally friendly products, clothing, homewear and art. The area has become popular among young people and expatriates owing to the low rent and peaceful setting.

Eastern village Sok Kwu Wan consists mainly of seafood restaurants and has the largest fish farming site in Hong Kong. Tourists can barbecue and fish at Lo Shing Beach which is ten minutes´ walk from the village.

The southern part of Lamma Island has minimal population, with access limited by treacherous hiking or private boat.
Sham Wan is one of the five most important archaeological sites in Hong Kong. It is also an important breeding site for sea turtles, the only species of turtle that breeds in Hong Kong, to lay eggs.
