Tawang Road Trip Guide: Guwahati to Tawang via Dirang & Sela
Tawang road trip guide: the 2-day Guwahati, Bhalukpong, Dirang, Sela route, top sights, Bum La permits, altitude and cold tips, and the best months to go.
To visit Arunachal Pradesh, Indian citizens from outside the state need an Inner Line Permit (ILP), and foreign nationals need a Protected Area Permit (PAP) instead. The easiest way for Indian travellers to get an ILP is online through the official Arunachal Pradesh eILP portal. This guide explains who needs what, the documents you will typically need, where permits are checked and the extra permissions for places like Bum La.
Permit rules, fees and processing times are set by the state and can change, so always check the official portal for current rules before you travel. We do not quote fees or timelines here.
What is the Inner Line Permit?
The Inner Line Permit is an official travel document that allows an Indian citizen who is not a resident of Arunachal Pradesh to enter and stay in the state for a limited period. The system dates back to colonial-era regulations and is meant to protect the state's tribal communities, land and culture. A few other Northeast states have similar systems, but each state issues its own permit, so a permit for one state does not work for another.
The ILP is valid for specific dates and, depending on the type, for specific districts or areas. Keep it with you throughout your trip, not just at the border.
Who needs which permit?
| Traveller | Permit needed |
|---|---|
| Indian citizens from outside Arunachal Pradesh | Inner Line Permit (ILP) |
| Foreign nationals | Protected Area Permit (PAP), usually arranged through a registered tour operator |
| Residents of Arunachal Pradesh | No ILP; carry your usual ID |
Children travelling with their family usually need to be included in the application too. Check the portal for how it handles minors.
Foreign nationals should note that the PAP has its own rules, which can include travelling in a group or through an approved operator, and limits on which areas are open. Check the latest requirements with the state government or an Indian mission well before you plan your dates.
How to apply for an ILP online
Arunachal Pradesh runs an official eILP portal for online applications. Search for the Arunachal Pradesh eILP portal and make sure you are on the official government website, which normally has a .gov.in address. Be careful of look-alike websites that charge extra or collect your details.
The process usually looks like this:
- Choose the type of permit, for example a tourist ILP for individuals or a group.
- Fill in your personal details, travel dates and the places you plan to visit.
- Upload a scanned photo ID and a recent passport-size photograph.
- Pay the permit fee online. The fee is generally nominal; check the portal for the current amount.
- Download the e-permit once it is approved, and keep both a printout and a copy on your phone.
Tip: Apply as soon as your dates are fixed, rather than the night before you leave. Processing times vary, and you cannot enter the state without a valid permit.
Some offices in Guwahati, Tezpur and other cities have historically issued ILPs in person, and there have been on-arrival options at certain points. These arrangements change, so do not rely on them. The online route is the safest option.
Documents you will typically need
- A valid photo ID: such as an Aadhaar card, voter ID, passport or driving licence. Use the same ID you will carry on the trip.
- A recent passport-size photograph in digital form, in the size and format the portal asks for.
- Travel details: your entry and exit dates and the districts or places you will visit, such as Tawang, West Kameng (Dirang, Bomdila) or Ziro.
- Details of everyone in your group, if you apply as a group.
Carry the original of the ID you used, plus a couple of photocopies and spare photos. They come in handy at checkposts and for extra local permits.
Entry checkpoints
Your permit is checked when you enter Arunachal Pradesh, and sometimes again at checkposts inside the state. Common entry points include:
- Bhalukpong: the main entry for the Tawang route, coming from Tezpur in Assam. See our Tawang road trip guide.
- Banderdewa: on the road to Itanagar and onwards to Ziro.
- Other gates in eastern Arunachal, used for routes from Upper Assam.
Make sure the places on your permit match where you are actually going. If your plans change, check whether you need to update or apply for a new permit.
Extra permissions for Bum La and some lakes
The standard ILP does not cover everything. Places close to the border, such as Bum La Pass near Tawang, and some high-altitude spots like Madhuri Lake (Sangetsar Tso), need additional permission. This is usually arranged in Tawang, often a day ahead, and visits also depend on army clearance and the weather. Bum La in particular can be closed at short notice.
Our drivers and local contacts in Tawang can guide you on the process when you arrive, but no one can guarantee a Bum La visit, so build some flexibility into your plan.
Tip: Keep at least two hard copies of your ILP in the car. Some local permits and hotel check-ins ask for a copy.
A few practical reminders
- Plan your route first, then apply, so the districts on your permit are correct.
- Check permit validity against your full trip, including the drive out.
- Respect photography restrictions near army areas and border zones.
- Rules change from time to time. Recheck the official portal close to your travel date.
