 · Malaysia is simply divided into six main regions, namely the Northern Region, Central Region, Southern Region, East Coast, Sabah, and Sarawak. You may break your visits down to several specific regions or better still, if time permits, visit the whole country. The best part about Malaysia is its size. It is small enough for you to take in ...
