Taman Negara National Park spans more than 2,500 square miles and is the oldest officially protected area in Malaysia.

It is also Malaysia's largest national park and has been developed into a major destination for ecotourism.

Carmen Roberts takes us on a journey into a pristine rainforest that is over 130 million years old.
