Exploration of the creeks and river banks produced a variety of amphibians and reptiles, as well as some scorpions. Trips were made to a waterfall and also up shallow creeks beds at night.

Amphibians documented included a Slender toad (Ansonia sp.), Kuhl's creek frog (Limnonectes kuhlii), Mjoberg's dwarf litter frog (Leptobrachium cf. mjobergi), Black-spotted rock frog (Staurois guttatus), and Yellow-bellied puddle frog (Occidozyga laevis) as well as at least two species of large ranid frogs that escaped before they could be identified or photographed.

There is an aerial walkway near Ulu Ulu where rainforest canopy birds and primates like gibbons can be observed, but it requires an early morning start and considerable climb up 270m of steps and 70m of vertical ladders steps to reach the viewing platforms and walkway which extends 150m across the canopy.
