Finely laid out botanical garden, for tourists 5 RM entry, for locals, like almost everywhere in Malaysia, a bit cheaper. Since there are 4000-5000 different plants in the area, you didn't need to create anything great, just lay a nice path through the rainforest and put signs on the plants, and the garden was done. Depending on your interest in plants, you can spend just 15 minutes or an hour here.
