After breakfast will have an hour drive to Gibon Wild Life Sanctuary, where we will have a nature walk of 2 and Half hour inside the park. The Hoollongapar Gibbon Sanctuary, is an isolated protected area of evergreen forest located in Assam, India. The sanctuary was officially constituted and renamed in 1997. Set aside initially in 1881, its forests used to extend to the foothills of the Patkai mountain range. The Hoollongapar Gibbon Sanctuary contains India's only gibbons – the hoolock gibbons, and Northeastern India's only nocturnal primate – the Bengal slow lories. In the nature walk we might witness some of the endangered species of primates such as the western hoolock gibbon, the stump-tailed macaque, northern pig-tailed macaque, eastern Assamese macaque, rhesus macaque, and capped languor .
