Mouling National Park is spread over districts of Upper Siang, West Siang and East Siang of Arunachal Pradesh. It is the second National park in Arunachal Pradesh after the Namdapha National Park. Mouling National Park is named after a nearby peak called Mouling peak. Mouling is an archaic word that means "red poison" or "red blood". This is believed to be red latex from a tree species found locally. The area is thought to have a large number of poisonous snakes, but this cannot be verified as the ecology of the area has been sparsely explored. The park is maintained by the Divisional Forest Office that is located in Jengging.
