There are quite a few hiking trails in the park, which are short but quite nice. The signs are not quite clear, so it is better to download hiking trail map app. We hike the tupai and burung trail for about 1 hour.
A natural fish spa by the river. The fishes are fairly big, so the spa experience could be quite "brutal".
There are a lot of fishes, with 3 species, and there are very human friendly. Buy some fish snacks (RM 0.50) to feed the fishes.
