Let’s start with the top mountain passes in Arunachal Pradesh that form the backbone of connecting the state with the outer world.

But before that, what is a mountain pass precisely? A mountain pass is a route among the mountain ranges, with the pass being the location point at which the altitude along the route is the highest.

In simpler terms, it means a winding road carved across the mountains, and if you take that road, you will pass through a point at which you will be at the highest altitude accessible of that group of mountains.

Humans make not all the mountain passes, but even glaciers, the path of streams running from the mountain tops, and natural events are how mountain passes are formed.

But most of the mountain passes developed are the ones that we use to commute between places. They have become an essential part of connecting and drawing borders between regions and protecting them.

So now that we know the basics, let’s begin to know about the best mountain passes in Arunachal Pradesh, shall we?

Diphu Pass, also known as Dipher Pass, is one of the strategically essential passes in Arunachal Pradesh, forming a critical border approach to eastern Arunachal Pradesh.

It is a mountain pass lying on the McMahon Line around the area of the tripoint borders of India, China, and Myanmar, which is disputed. Diphu Pass is located in Anjaw district, 120 km northeast of district headquarter in Hawai via the Hawai-Walong-Dong-Kibithu-Kaho-Dhipu Pass route.

In October 1960, China and Burma demarcated their border to Diphu Pass, 5 miles south of the watershed of the mountain ranges. However, this caused a diplomatic row with India, which expected the tri-point to be a watershed. 

The dispute still exists and has become part of the border disagreement between China and India regarding Arunachal Pradesh, an issue for many decades.

Pangsau Pass or Pan Saung Pass, located on the crest of the Patkai Hills on the India–Myanmar border, connects both countries. At 3,727 feet (1,136 m) in altitude, it is one of the high-altitude mountain passes in Arunachal Pradesh. 

It is named after the closest Burmese village, Pangsau lies 2 km to the east beyond the pass. Pangsau Pass became the centre of attention during the British occupation of India in the late 19th century. 

The British saw the pass as a way to establish a railway connection between India and Burma, both being their colonies.

After an extensive survey covering several towns and villages around the pass, they concluded that a track could be pushed through to Burma and down the Hukawng Valley. 

Similarly, a road from Assam into northern Burma had been planned in the Patkai range. None of these was materialised, however.

Later on, during World War II, the pass became famous because of the Stilwell Road (Ledo Road) connecting British India to Nationalist Chinese forces fighting the Japanese in China.

Sitwell Road connected Ledo to Pangsau Pass. The distance between them was 61km, which began at Ledo in Assam and passed through several towns before switchbacking steeply upwards through densely forested hills Pangsau pass.

Since 2007, Pangsau Pass has been the venue for the Pangsau Pass Winter Festival, a joint India-Myanmar 3 day fest organised during the 3rd week of January every year in Nampong, Arunachal Pradesh.
