We visited the highly accessible Kepong Botanic Gardens (FRIM) and the Forest Skywalk. Frederick Dawson's review covers the less accessible portion of FRIM (worth reading). We enjoyed our weekday morning visit to Kepong Botanic Gardens. Upon arrival we took a forest trail and the shaded coolness was a particularly pleasant reprieve from the high temperature humidity. The dense under-story plants hide all trace that this area was a product of reforestation.

Afterwards, we made our way to the Forest Skywalk. Since it was a Tuesday morning, we were the only people on the structure. The highlights are looking down from the canopy toward the forest floor, views of the forested hills and nearby pond. All pleasantly scenic, but after visiting the Treetop Walk at Singapore's MacRitchie Reservoir Park, it was a bit underwhelming.
The Kepong Botanic Gardens (FRIM) is a fine introduction to this world heritage site. However, its a shame you cannot simply cross over from the botanic garden area to to the forest reach center.
