Naga hills, reaching a height of around 3825 metres, lie on the border of India and Burma (Myanmar). These hills are part of a complex mountain system, and the parts of the mountain ranges inside the Indian state of Nagaland and the Burmese region of Sagaing are called the Naga Hills. The hills, due to their complexity and position form a barrier between the two countries. The Naga Hills are part of the Arakan Range (Rahkine Range) which to the north rise to 12,552 feet. The term Naga refers to the Naga people who were called Naga or Naka in the Burmese language, which means 'people with pierced ears'.
