Arunachal Pradesh, the "Land of Dawn-Lit Mountains," beckons adventure seekers and nature enthusiasts with its breathtaking landscapes, rich cultural heritage, and ancient monasteries. Nestled amidst the majestic Himalayas, this northeastern state boasts one of India's most remarkable engineering feats – the Sela Tunnel.
For decades, travellers venturing to Tawang, the crown jewel of Arunachal Pradesh, had to navigate the treacherous Sela Pass. This high-altitude mountain pass, perched at over 13,700 feet, was prone to harsh weather conditions and year-round snowfall, often restricting access to Tawang for several months. However, the inauguration of the Sela Tunnel in March 2024 by Prime Minister Narendra Modi has transformed travel in the region.
Constructed by the Border Roads Organisation (BRO), the Sela Tunnel is a marvel of modern engineering. This high-altitude tunnel, the world’s longest bi-lane tunnel at this height, bypasses the Sela Pass, ensuring year-round connectivity to Tawang. The tunnel complex consists of two tunnels and a link road, allowing for a seamless and swift passage through the once-daunting mountain pass.
With the ease of access provided by the Sela Tunnel, Arunachal Pradesh tourism is expected to flourish. Several tour operators are now offering Tawang tour packages, catering to various interests and budgets. These packages typically include visits to the Tawang Monastery, the largest Buddhist monastery in India, exploration of the serene Gompas (monasteries) scattered across the region, and excursions to natural wonders like the Shonga-Tser Lake.
For the intrepid traveller, an Arunachal Pradesh road trip offers an unparalleled adventure. The state boasts a network of scenic highways, winding through lush valleys, cascading waterfalls, and snow-capped peaks. A road trip itinerary can be customized to include visits to Bomdila, another beautiful hill station, Dirang, famous for its hot springs, and Ziro Valley, a UNESCO World Heritage Site known for its rice paddies and tribal villages.
On Saturday, March 10, 2024, Prime Minister Narendra Modi inaugurated the Sela Tunnel in Arunachal Pradesh, marking the debut of the world's longest twin-lane tunnel. This strategic infrastructure project is poised to significantly enhance connectivity in the region, reinforcing the government's commitment to bolstering transportation networks in challenging terrains.

Sela Pass, located on the road connecting the town of Bomdila and Tawang, is primarily accessed via the Assam gateway. While the new Sela Tunnel has made the journey smoother and all-weather accessible, here is a guide on reaching the region from the nearest major city.
Nearest Major City: Guwahati serves as the main gateway to the entire Northeast region. It has the biggest airport and railway station nearby.
Route: The journey involves travelling from Guwahati to Tezpur, then onwards to Bhalukpong (the Arunachal Pradesh border checkpoint), and finally through Bomdila and Dirang towards Sela Pass/Tawang.
Distance/Time: Guwahati to Sela Pass is approximately 450-500 km and takes about 16-18 hours of continuous driving, usually broken into a two-day trip with a night halt in Bomdila or Dirang.
Nearest Air/Rail Link: Tezpur (via Tezpur Airport or Dekargaon Railway Station) is the closest transportation hub outside of Arunachal Pradesh.
Route: From Tezpur, you drive directly to Bhalukpong, then follow the Inner Line Permit (ILP) process, and proceed to Bomdila and Dirang. The road ascent starts heavily after Dirang.
Distance/Time: Tezpur to Sela Pass is about 280-300 km and takes roughly 10-12 hours, typically requiring a night halt to adjust to the high altitude.
All non-Arunachal Pradesh residents must obtain an Inner Line Permit (ILP) to enter the state. This permit must be checked and validated at the Bhalukpong checkpoint before proceeding towards Sela Pass. Plan to obtain this in advance online or at major railway stations like Guwahati.
The Sela Tunnel, situated at an elevation exceeding 13,000 feet, is poised to become the world's longest bi-lane tunnel, strategically addressing challenges posed by snowfall and landslides on the Ballipara–Chariariduvar–Tawang Road. Orchestrated by the Border Roads Organisation (BRO), the project encompasses two tunnels and a link road.
Tunnel 1 spans 980 metres, featuring a single-tube design, while Tunnel 2, stretching 1,555 metres, is a twin-tube structure with one dedicated bi-lane for traffic and the other for emergency services. Connecting these tunnels is a 1,200-metre link road, ensuring seamless connectivity.
The foundation stone for the Sela Tunnel project was ceremoniously laid by Prime Minister Modi on February 9, 2019. The realization of this ambitious venture demanded an impressive effort, with over 90 lakh man-hours contributed by an average of 650 workers and labourers daily over the past five years.
The construction entailed the use of substantial resources, including approximately 71,000 metric tonnes of cement, 5,000 metric tonnes of steel, and 800 metric tonnes of explosives. The Sela Tunnel not only exemplifies engineering prowess but also signifies a significant stride towards bolstering all-weather connectivity in the challenging terrains of Arunachal Pradesh.
The Sela Tunnel project comprises two tunnels and an access road, totaling approximately 12.04 km. The main tunnel (Tunnel 2) is a twin-tube structure measuring 1,555 meters in length, and the smaller tunnel (Tunnel 1) is 980 meters long.
The Sela Tunnel connects Tawang to the rest of the country via the Ballipara–Chariariduvar–Tawang Road network. Specifically, it bypasses the treacherous Sela Pass and provides all-weather connectivity to the region.
