Deep in a 130-million year old rainforest is Danum Valley Conservation Area which is a research centre but sometimes allows a few visitors. The dense jungle is one of the world's biodiversity hotspots and is home to giant trees, orangutans, pygmy elephants, extremely rare pygmy rhinoceros and a host of other mammals, insects, reptiles and amphibians making it a nature-lover's paradise. #rainforest #borneo #flora #fauna #wildlife #photography #waterfalls #hiking #nature
