Previously known as Shemgang, has been closed to tourist for a long time. As it borders Assam in India its southern forests where known to be guerilla bases. In 2003 the King of Bhutan led an attack to which swept the guerillas out of the region. Now a small part of this region has been opened and its absolute delight for bird watchers. In some parts of this region the animist traditions of Bhutan are still practiced. Royal Manas National Park covers a part of Zhemgang along with Jigme Singye Wangchuck and Thrumshingla National Park. Around 86% of Zhemgang is under thick forest.
