An hour or two east of Kuala Lumpur, in the forests of Pahang, sits the Kuala Gandah Elephant Conservation Centre: a government-run sanctuary that relocates and cares for elephants displaced by shrinking habitat. In May 2010 we spent a day there, and it rearranged our hearts a little.
Visiting hours revolve around the residents' daily routine, and the highlight is feeding time. The keepers hand you fruit, point you at an elephant, and let the two of you work out the rest.
If your Malaysia plans revolve around Kuala Lumpur, this is the day trip we would argue for first. You go for the elephants; you leave quietly rooting for the people who look after them.
