Bus

Bus travel is an option for the road journey from Guwahati to Tawang, but there are no direct buses from Chennai to Tawang. You will need to combine bus and train or flight travel.

• From Chennai, you can take a bus or train to Guwahati, then board an Arunachal Pradesh State Transport (APST) bus or private bus to Tawang.

• APST buses run regularly from Guwahati to Tawang, covering the hilly terrain with stops at key towns like Tezpur and Bomdila. The journey takes about 16 to 18 hours.

• Plan overnight stops in major cities like Nagpur, Guwahati, and Tezpur to rest and refuel. Booking accommodations in advance is advisable during tourist seasons.

• Carry essential documents such as vehicle registration, insurance, and permits required for Arunachal Pradesh, as it is a restricted area for Indian citizens without an Inner Line Permit (ILP).

Step-by-Step Travel Plan

This step-by-step plan is designed for first-time travelers from Chennai to Tawang, helping you organize your journey smoothly and avoid common challenges.

• Carry snacks from Chennai for the long journey, as food options on remote highway stretches can be limited and not always hygienic.

• Keep your luggage light and secure, as multiple transfers between trains, buses, and taxis increase the risk of loss or damage.
