Located in the Malaysian state of Sarawak, on the large rugged island of Borneo, the Batang Ai National Park features an impressive 24-square-kilometre expanse of lush tropical rainforest containing an extraordinary array of rare and protected wildlife. The park lies at the headwaters of the Batang Ai and the Lubang Baya river and is accessible only by chartering boats which travel up the river, through thick jungle, and across the magnificent Batang Ai Lake. Visitors can look forward to exhilarating mountain treks, spotting orangutans, gibbons, hornbills and other exotic wildlife; and interacting with the local indigenous people, many of whom continue to live in traditional communal dwellings known as longhouses.
