How to Travel Tawang

Getting to Tawang — two days of road from the nearest airport

Tawang has no airport and no railway, and at roughly 3,000 m in the far north-west of Arunachal Pradesh it is one of the longest approaches of any town in India. Guwahati is about 480–520 km away and 14–16 hours of driving — normally split over two days with a night at Bomdila or Dirang. Tezpur, at around 330–385 km and 12 hours, is the closer and more common starting point. Plan the journey as two days and it is one of the great drives in the Himalaya; plan it as one and it is a punishing overnight.

✈️ Where you start

Guwahati (GAU) — The usual gateway: the Northeast's busiest airport and a major rail hub. From Guwahati the road runs Tezpur → Bhalukpong → Bomdila → Dirang → Tawang on NH13.

Tezpur (Salonibari) — Closer, with limited flights from Kolkata and Guwahati. This is where the cheapest onward transport actually leaves from, so most budget travellers make their way to Tezpur first.

Rail — There is no railway in Arunachal's hills. Guwahati is the major junction; Rangapara North and Tezpur are the closer, smaller stations. All of them mean a long road leg afterwards.

🚕 Onward from Assam

Shared Sumo — The backbone of this route. They leave from Tezpur early in the morning for Tawang at roughly ₹1,200–1,800 a seat, and from Paltan Bazaar in Guwahati at around ₹800–1,000 for the Assam-side legs. Departures are daily but they go when full, so arrive early.

Government bus (APSTS) — ₹500–700 one way, 16–18 hours, typically with an overnight halt at Bomdila or Dirang. Tezpur–Bomdila services historically run on specific days rather than daily, so check the current schedule rather than assuming.

Private taxi — ₹15,000–20,000 for a four-to-six-day round trip from Guwahati. The only option that lets you stop at Sela Pass, Nuranang Falls and the Dirang valley on your own schedule. Worth it for four or more people.

App cabs do not operate here. Uber and Ola will not take you into Arunachal Pradesh and will not appear in the app once you are in the hills. Everything is arranged at a Sumo stand, through a Guwahati or Tezpur agency, or via your hotel.

🛣️ The road, and the Sela Tunnel

Sela Pass at 4,170 m was the reason Tawang used to be cut off for weeks every winter. Since March 2024 the Sela Tunnel carries traffic under the pass, so the town is no longer isolated by snow. The old road over the top is still there and still open, and that is where you stop for Sela Lake and the snow views — after heavy snowfall the surface road can close while the tunnel keeps running.

Legs and times: Guwahati → Tezpur 180 km, 4–5 hrs · Tezpur → Bomdila 150 km, 5–6 hrs · Bomdila → Tawang 170 km, 6–7 hrs. From June to September rain and landslides can slow the Bhalukpong–Bomdila stretch badly.

📋 Permits — sort this before you travel

You cannot simply drive into Arunachal Pradesh. Indian visitors need an Inner Line Permit, issued online as an e-ILP through the state portal, usually within 24–48 hours for around ₹100 a person, and checked at the Bhalukpong gate on the road from Assam. List both Tawang and West Kameng as your districts so the whole Guwahati–Tawang route is covered. Validity is typically 15 days and extendable.

Foreign nationals need a Protected Area Permit, arranged through a registered Arunachal tour operator, generally for groups of two or more and valid up to 30 days.

If the online process fails you, ILPs can be issued in person at Deputy Resident Commissioner offices in Guwahati, Tezpur, Shillong, Kolkata and New Delhi, and there is an Arunachal Tourism counter at Guwahati airport arrivals that issues them on the spot.

A second, army-endorsed permit is needed for Bum La and Madhuri (Sangetsar) Lake. It sits on top of your ILP, is open to Indian citizens only, is issued in Tawang town, and is valid for a single day — so plan an extra morning for it and do not assume you can get it the same day you arrive.

💡 Things that go wrong

Do not attempt it in one day from Guwahati — Fourteen to sixteen hours of mountain road, ending above 3,000 m, with the last stretch after dark. Break the journey at Bomdila or Dirang; it also helps your body adjust before Sela.

Carry cash — ATMs in Tawang do run dry, and you will need notes for the Bum La permit trip and for villages on the road where nothing electronic works.

Signal is patchy beyond town — Do not rely on maps or on contacting a driver once you are in the hills.

Best months are October–November and March–April — Clear skies and open roads. Winter is very cold with snow; June to September brings rain and landslide delays.

Give Tawang at least three nights — One day for the monastery, the War Memorial and town; one for the Bum La and Sangetsar permit trip, which starts early and eats the whole day; one for Nuranang Falls and the smaller gompas, or to recover. Take the first afternoon slowly at this height and skip alcohol on night one.

Shops shut early and dinner runs early — Do not plan on eating out late.
