Pulau Ketam, literally translated, means "Crab Island". It is a small island located off the coast of Port Klang, Selangor, Malaysia, and was founded circa 1880. The island is easily accessible from the Port Klang jetty by ferry. The "floating houses" that come to view as visitors approach the island are a sight to awe any city slickers. Perching casually on long wooden stilts, these dwellings are suspended about one to ten (1-10) metre above sea level. The main thoroughfares are narrow concreted pavements, whilst in the residential areas, the older rickety wooden plank bridges can still be seen. There are no cars in Pulau Ketam, only bicycles, some of which are motorised.
Pulau Ketam is equipped with almost all the basic facilities. It also plays a role as a major fish, crabs, prawns provider to Klang valley and a tourism spot of Negeri Selangor. Ferry services are available everyday. The journey takes will take about 30 minutes. Beside ferry, speedboat is also available 24 hours per day on call. If you have cargoes to deliver, cargo boats are available too. The locals are mainly Teochew and Hoklo (Hokkien) Chinese, with Teochew, Hokkien and Mandarin Chinese the main dialects spoken.
