Almost 40% of the area is preserved as Ulu Temburong National Park and is considered one of the world's most diverse ecosystems with a range of wilderness habitats, from lowland forest and jungle rainforest to mountain forests and waterfalls. Most of the park is untouched by man and the traditional culture of Borneo longhouse communities (where an extended family or several families live together in a single, long home) remains intact. Home to the rare Proboscis monkey and thousands of unique species of plants and animals, access is via traditional longboats along river corridors or jungle hiking tracks -- there are no roads into the park. A series of canopy walkways rising over 180 feet above the tree tops and long suspension bridges give new definition to the term "back to nature."
