Heading up the KL Tower for views of the city and the world’s former tallest buildings the Petronas Towers is ok. But Kuala Lumpar overall is a bit of an unpleasant hodgepodge of super modern malls and skyscrapers with still quite underdeveloped and at times poverty spots right in the city.
Fly in, and get out to the real highlights of Malaysia which sit outside of its capital.
Or, if looking for a South East Asia big city break, put Bangkok, Phnom Penh, Yangon, Ho Chi Minh, Singapore and Hanoi (for its old town) way ahead of KL.
