Tawang in Arunachal Pradesh has no airport of its own. Fly into Tezpur or Guwahati in Assam, then travel the rest of the way by road, a long mountain journey that the Sela Tunnel has made usable through more of the year. Indian citizens who are not residents of Arunachal Pradesh need an Inner Line Permit, applied for online in advance, and weather can disrupt both flights and the road at short notice.

Tawang’s remoteness is part of its appeal, but it does mean more planning than a direct flight. Here is how the journey actually breaks down.
Which airports are nearest to Tawang?
Tawang has no commercial airport. The two realistic air gateways are Tezpur Airport (TEZ) in Assam, which is the closer of the two and cuts down the road portion of the journey noticeably, and Guwahati Airport (GAU), which has far more flight connections from the rest of India but means a longer onward drive. Most travellers coming from outside the Northeast fly into Guwahati first, since it has the widest range of domestic connections, and then either continue by road or look at the limited helicopter option described below.
Do you need a permit to visit Tawang?
Yes. Indian citizens who are not natives of Arunachal Pradesh need an Inner Line Permit (ILP) to enter the state, and this single permit covers Tawang along with the rest of your route through the state. The permit is applied for online through the state government’s official ILP portal, and involves uploading a photo ID such as Aadhaar, a passport-sized photograph, and your travel dates and planned places of stay, along with a modest fee. Processing is usually quick for an online application, but it can take longer during the peak travel season from October to March, so apply at least a week before you travel rather than at the last minute. Be careful to use the official government portal directly; there are agent sites that charge extra for a permit you can get yourself for a small fee.
How has the Sela Tunnel changed the road journey?
The route from Tezpur or Guwahati to Tawang runs through high mountain terrain, including the Sela Pass, which used to be prone to heavy snow closures in winter. In March 2024, the Prime Minister inaugurated the Sela Tunnel, a twin-lane tunnel built under the pass at an elevation of roughly 13,000 feet, built by the Border Roads Organisation specifically to keep this stretch open through more of the year, including winter. This has made the overland approach to Tawang meaningfully more reliable than it used to be, though it does not remove all weather risk on the rest of the route, since other sections of mountain road can still be affected by rain, landslides or snow outside the tunnel itself.
Is there a helicopter option from Guwahati?
A limited helicopter service connecting Guwahati and Tawang has operated at various times, run by Pawan Hans, typically on only a few days of the week and with very few seats available per flight. This service is frequently affected by weather, technical issues, VIP movement and other priority needs, so it should be treated as a possibility to inquire about rather than something to build a fixed itinerary around. Bookings for this service have generally needed to be made in person or by phone with the operator rather than through standard online travel booking, so confirm current operating days and availability directly with Pawan Hans before counting on it.
What should you plan around for weather?
Tawang sits at high altitude and its approach roads climb through mountain passes, so expect cold conditions for much of the year and genuinely harsh winter weather with snow possible, particularly from around December through February. Both flights into Tezpur and Guwahati and the onward road journey can be delayed or disrupted by fog, rain or snow, so build slack into your itinerary, especially if your trip is time-bound, and avoid scheduling a return flight for the same day you plan to leave Tawang.
Common Questions
Can foreign nationals visit Tawang?
Foreign nationals require a different permit process than the Inner Line Permit used by Indian citizens, and rules for foreign travellers in protected areas of Arunachal Pradesh have changed over time. If you are not an Indian citizen, check current requirements with the Arunachal Pradesh government or an Indian embassy well before you plan your trip.
How long does the road journey from Guwahati to Tawang take?
It is a long multi-day style journey across mountain roads, and most travellers break it up with an overnight stop rather than attempting it in one push. Exact driving time depends heavily on road and weather conditions on the day, so treat any specific time estimate you read online as approximate.
Is Tezpur a better option than Guwahati for reaching Tawang?
Tezpur is closer to Tawang by road than Guwahati is, which can save meaningful travel time, but Guwahati has many more flight options from across India. Many travellers fly into Guwahati for better connectivity and either continue by road from there or connect onward to Tezpur.
Can I get the Inner Line Permit on arrival?
The straightforward route is to apply online in advance through the official portal. Arranging it only after you arrive adds risk and delay, particularly in the busier October to March travel season, so it is best treated as a pre-trip task, not something to sort out on the ground.
Does the Sela Tunnel mean the route is open all year now?
The tunnel has made this specific stretch far more usable through winter than it was before, but it has not eliminated all weather-related disruption on the wider route to Tawang. Always check current road conditions before you travel, especially in winter.
