Hoolangapar Gibbon Sanctuary is located in Jorhat, Assam and spreads across an area of about 21 km sq. It is home of India's only Gibbons population -Hoolock Gibbons. Not just the Gibbons, it also houses 7 species of monkeys out of total 15 species that are found in India, varied species of birds, spiders and squirrels. Gibbons are the Apes and are differentiated on smaller size, lower sexual dimorphism, no nesting habits from the Greater Apes. Hoolock gibbons are the second largest of the gibbons and spread from NE India to Myanmar, with smaller populations in Bangladesh and China. Hoolangapar Sanctuary provides an unparalleled opportunity to meet these gibbons in their natural habitat. Also, the sanctuary has India's only population of nocturnal primates- the Slow Loris. With distinctive large eyes, every species of Slow Loris has been identified either Vulnerable or Endangered. Spiders represent the other attraction for macro-hunters, with large webs and colorful tentacles - they naturally attract their victims as well as photo-enthusiasts. How to reach?
