Peninsular Malaysia is part of the Malay Peninsular between Thailand in the north and Singapore in the south.
Loosely speaking, the peninsular is divided into the eastern and western coastal stretches, with marked differences in the ethnic composition of the various regions, with ethnic Malay, Chinese, Indian and other influences strongly felt in this diverse region.
The western, southern and northern parts are generally far more populated than the east coast, which is physically divided from the west by the mountainous interior. The eastern states never attracted the immigration that affected others parts of Peninsular Malaysia. The result is untouched golden beaches and peaceful, serene islands just off shore. It is also seen as the heart of Malay culture and is the most conservative part of Malaysia.
In the northwest, the small city of Penang dominates. Though it has beaches, the real draw here are the lovely old streets of Georgetown. For beaches, go a little further to the north and Langkawi, an island which shares many characteristics with its Andaman neighbours in Thailand to the north.
In the southern western part of Malaysia is the capital Kuala Lumpur and the once great port of Malacca, still very much worth visiting for its historical legacy as a cultural melting pot.
