After breakfast, we proceed to Hoollongapur Gibbon Wildlife Sanctuary. Originally established in 1881 when the land was put aside for preservation. The area is rich in biodiversity and is home to the Western Hoolock Gibbon, India's only gibbon. The area is also home to other members of the primate family such as the Stump Tailed Macaque, Rhesus Macaque, Northern Pig-tailed Macaque, Eastern Assamese Macaque and Capped Langur. The park is also home to Indian elephants, tigers, leopards, boar and 219 species of bird. Overnight stay at Gibbon Resort,{The Hoollongapar Gibbon Sanctuary, formerly known as the Gibbon Wildlife Sanctuary or Hollongapar Reserve Forest, 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. Since then, the forest has been fragmented and surrounded by tea gardens and small villages. In the early 1900s, artificial regeneration was used to develop well-stocked forest, resulting in the site's rich biodiversity. The Hoollongapar Gibbon Sanctuary contains India's only gibbons the hoolock gibbons, and Northeastern India's only nocturnal primate the Bengal slow loris. The upper canopy of the forest is dominated by the Hollong tree (Dipterocarpus macrocarpus), while the Nahar (Mesua ferrea) dominates the middle canopy. The lower canopy consists of evergreen shrubs and herbs. The habitat is threatened by illegal logging, the encroachment of human settlements, and habitat fragmentation.}
