Bumla Pass Permit: The Application Process

Your Inner Line Permit gets you into Arunachal Pradesh. It does not get you onto the road to the Line of Actual Control. Bumla Pass, PT Tso and Sangetsar Lake are visited in an authorised local vehicle from Tawang, and access is controlled jointly by the district administration and the Army, so a separate clearance naming each traveller and the vehicle is completed locally in Tawang town. Access cannot be guaranteed in advance and is subject to permit formalities, Army clearance, weather, security and road conditions.

The same clearance normally covers Sangetsar (Madhuri) Lake, which is why the two are almost always done on one day.

Applications are made at the Deputy Commissioner's office in Tawang, which then goes to the Army garrison for endorsement. The office works government hours on working days, and processing timing varies rather than following a fixed schedule. This is the practical reason itineraries put a spare day in Tawang around the border run rather than assuming it can be completed on arrival morning.

Original government photo ID for every traveller (Aadhaar, voter ID, passport or driving licence), photocopies of the same, at least two passport-size photographs per person, your ILP, and the vehicle and driver details. Children need ID too — a birth certificate or school ID is accepted. A digital copy on your phone is not sufficient for the application.

In most seasons the Bumla and Sangetsar leg must be run in a locally registered vehicle with a local driver, hired in Tawang, rather than the vehicle you arrived in. This is enforced by the local taxi union and the administration together. Budget for it — it is a separate cost from your main vehicle and a common surprise for travellers who booked on a headline rate elsewhere.

Snow closing the road is the most common reason, and it is decided on the morning, not the night before. Military activity or tension along the LAC closes the pass without notice or explanation. Documents that do not match — a nickname on one paper and a legal name on another — get rejected outright. Foreign nationals are refused as a matter of standing policy, regardless of visa or PAP status.

Access to Bumla cannot be guaranteed in advance. Any operator who claims otherwise is promising something they do not control. Build the itinerary so a closed pass costs you a morning, not the trip.

Carry the original permit and your ID; there are checks on the way up. Leave Tawang early — the pass is usually cleared for visitors in the morning window and the weather deteriorates through the afternoon. There are no facilities beyond the Army canteen, no fuel, and no mobile network. Expect to spend twenty to thirty minutes at the top, which is all that the altitude and the Army allow.
