Here is a video I made during my visit to Gua Damai Extreme Park with my parents and uncle and aunties from Tourism Malaysia Selangor.
It was really amazing. You can do extreme sports here. There is rockclimbing, abseiling and cave exploration too. You can also visit if you want to. Below is the info:
