It depends how long you gonna stay in Malaysia. If you are in Kuala Lumpur, be sure to visit the Twin Towers and also KL Tower. :) If time persist, you may go Cameron Highlands.

In KL the Petronas Tower are worth a look as well as Chinatown during the day or night. We stayed at the Sol Melia and the area right behind it during the night was pretty lively, I think the street is called Jalan Bukit. Great and cheap massages right on the street.
I going to Borneo... seeing Orangutans (or at least trying to) in Sabah would be my recommendation. over 7 years ago
