Namdapha National Park & Tiger Reserve, located in Arunachal Pradesh's Changlang district, is one of India’s most biodiverse and remote wilderness areas. Spanning an area of 1,985.23 sq. km along the India-Myanmar border, it features dense, untouched tropical rainforests and is home to the turbulent Noa-Dihing River.

Situated near the town of Miao, Namdapha was declared a Tiger Reserve in 1983. The park is a treasure trove of flora and fauna, much of which remains scientifically unexplored. With over 150 species of timber, it’s often called a botanist’s dream. Rare plants like the Blue Vanda orchid and the highly valued medicinal herb Mishmi Teeta (Coptis teeta)—used by local tribes—are found here. Notably, tree species such as Pinus merkusii and Abies delavayi grow here and nowhere else in India.

Namdapha is the only national park in the world that hosts all four major big cat species: the Tiger, Leopard, Snow Leopard, and Clouded Leopard. It also shelters several smaller wild cats, elephants, Himalayan black bears, Indian bison, and a wide range of primates, including the rare Hoolock Gibbon—India’s only ape species.

With its raw beauty, ecological richness, and scientific significance, Namdapha remains one of India's most pristine and enigmatic natural sanctuaries.
