I recommend visiting - Kinabatangan River, Borneo
The lower basin of the Kinabatangan River boasts one of Malaysian Borneo's most diverse lowland habitats and is positively teaming with wildlife. Meandering along the river, through oxbow lakes and up various tributaries with a local nature guide, you have the chance to see rare and endangered animals, many endemic. Wildlife you could see includes proboscis monkey, orangutan, estuarine crocodile, and pygmy elephant. There is also a spectacular array of birdlife.
