Tawang Road Trip Guide: Guwahati to Tawang via Dirang & Sela

The road trip from Guwahati to Tawang is usually done over two days: Guwahati to Dirang via Bhalukpong on the first day, then over the Sela Pass to Tawang on the second. It is one of the most dramatic drives in India, climbing from the Assam plains to well over 4,000 metres. This guide covers the route, the sights, permits, altitude, the best months and why the driver you choose matters.

Tip: Indian visitors from outside Arunachal Pradesh need an Inner Line Permit before crossing into the state at Bhalukpong. Read our Arunachal ILP guide and apply before you travel.

The route over two days

Day 1: Guwahati to Dirang (via Tezpur and Bhalukpong)

From Guwahati you drive north-east through the plains towards Tezpur, cross the Brahmaputra and head to Bhalukpong, the entry checkpoint into Arunachal Pradesh. This first part is roughly 5 hours. Your permits are checked here.

After Bhalukpong the road starts climbing through forest along the Kameng river, past Tenga and up to Bomdila, then down into the Dirang valley. In total, Day 1 is a long day of about 9 to 11 hours on the road, so leave Guwahati early, ideally by 6 am. If you prefer shorter days, break the journey at Bhalukpong or Bomdila instead.

Dirang, at roughly 1,500 metres, is a good place to sleep before going higher. It has apple and kiwi orchards, a hot spring and the old Dirang Dzong area.

Day 2: Dirang to Tawang (via Sela)

Dirang to Tawang is roughly 135 to 145 km and usually takes about 5 to 7 hours, depending on the road, weather and how often you stop. The road climbs steeply towards Sela, at roughly 4,170 metres (about 13,700 feet).

The Sela Tunnel, opened in 2024, now gives an all-weather route that bypasses the highest section of the pass and is meant to keep the road open more reliably in winter. Most tourists still want to see Sela Lake and the pass itself, so check with your driver on the day whether to take the tunnel, the old pass road, or both, depending on weather and road status.

After Sela you descend past the Jaswant Garh war memorial and Jang, with the Nuranang (Jang) waterfall nearby, before climbing again to Tawang, at roughly 3,000 metres.

What to see in and around Tawang

  • Tawang Monastery: a large and important Buddhist monastery founded in the 17th century, set on a ridge above the town. Visit in the morning to hear prayers.
  • Tawang War Memorial: a stupa-style memorial to soldiers who died in the 1962 war, with an evening light and sound show on many days.
  • Sela Lake and Sela Pass: high-altitude lake beside the pass, often frozen in winter.
  • Madhuri Lake (Sangetsar Tso): a striking lake with dead tree trunks standing in the water, roughly 40 km from Tawang on a rough road.
  • Bum La Pass: on the India–China border at around 4,600 metres, visited with army supervision.

Madhuri Lake and Bum La need extra permits beyond the standard ILP. These are typically arranged in Tawang a day in advance, and visits depend on weather, road conditions and army clearance on the day. Bum La can be closed at short notice, so treat it as a possibility, not a guarantee. Rules change, so check locally when you arrive.

Plan at least two full days in Tawang: one for the town sights and one for Madhuri Lake and Bum La if permits come through.

Altitude and cold: how to stay well

Going from near sea level in Guwahati to over 4,000 metres at Sela in about two days is a big jump. Altitude sickness can affect anyone, regardless of fitness.

  • Sleep low, then go high. Spending the first night at Dirang helps your body adjust.
  • Do not linger at Sela or Bum La. Take your photos and move on; 20 to 30 minutes at the top is plenty.
  • Drink plenty of water and avoid alcohol for the first couple of days.
  • Watch for symptoms: headache, nausea, dizziness or breathlessness at rest. Tell your driver and descend if they get worse.
  • See a doctor before the trip if you have heart, lung or blood pressure conditions, or are travelling with infants or elderly parents.
  • Dress in layers. Thermals, a fleece, a down or padded jacket, gloves, a woollen cap and good shoes, even in summer. Sela can be cold and windy year-round.
Tip: Carry some cash. ATMs exist in Tawang, Bomdila and Dirang, but network and card payments can be unreliable on the way.

Why an experienced hill driver matters

The Tawang road has long climbs, tight bends, sections under construction, and stretches where landslides or snow can block traffic for hours. Army convoys use the same road. A driver who knows this route will:

  • Plan start times so you cross Sela in daylight and in the best weather window.
  • Know where to stop for food, fuel and toilets, which are limited in places.
  • Drive in low gear on steep descents and handle snow, slush and loose gravel safely.
  • Read the road situation and change plans when needed, rather than pushing on.

For this route a sturdy SUV such as an Innova Crysta or Ertiga is usually the right choice, and a Tempo Traveller can work for larger groups in good season.

Frequently asked questions

How many days do you need for a Tawang trip from Guwahati?

Plan at least 6 to 7 days in total: two days each way on the road plus two or more days in Tawang. Rushing it leaves little time to adjust to the altitude.

Do I need a permit for Tawang?

Indian visitors from outside Arunachal Pradesh need an Inner Line Permit, and foreign nationals need a Protected Area Permit. Bum La and Madhuri Lake need extra permissions arranged locally.

Is Bum La Pass always open to tourists?

No. Visits need a separate permit and army clearance, and the pass can close at short notice due to weather or other reasons. Treat it as possible, not guaranteed.

What is the best time to visit Tawang?

March to May and October to November are usually the best windows. Winter brings snow and possible closures, and the monsoon makes landslides more likely.

Does the Sela Tunnel mean I miss Sela Lake?

Not necessarily. The tunnel bypasses the highest section, but in good conditions you can usually still take the old pass road to see the lake. Your driver will advise on the day.
