Taking its name from the two rivers that flow through it, Endau-Rompin National Park is a naturalist's fantasy of indigenous rainforest flora and fauna. There are many hiking trails, as well as herds of elephant or the croaking of rare frogs within range of both your eyes and ears.
A few great sites include waterfalls like the Buaya Sangkut, which is the prize at the end of a physically demanding climb up Semanggong Hill; as well as the Upeh Guling Waterfalls, which are famous for their 240 million year old volcanic rock. If interested in the native Orang Asli, make sure to visit Kampung Peta, which is a short drive from the park headquarters. Just make sure to be as respectful as possible and please ASK if you are going to take pictures.
Note:The included website has a lot of in-depth information about this park, as well as some tour information for those who would rather enter the rainforest with a guide.
