The Dzukou Valley, popularly known as the ‘valley of flower’. It is located at the border of Nagaland and Manipur. It is situated at an altitude of 2,438 metres behind the Japfu mountain range, it is one of the most popular trekking spots in the North East.

• Dzukou valley and Japfu peak are located adjacent to the Pulie Badze Wildlife Sanctuary (Nagaland).
• The Pulie Badze Wildlife Sanctuary (PWS) is located at Kohima District of Nagaland. The sanctuary is a natural habitat for Blyth’s Tragopan (Nagaland’s state bird), the Rufous-necked Hornbill and the Dark-rumped Swift, among many others.
