If you want to travel to Itanagar City centre (Ganga market) or Naharlagun township in a public transport, there are 2 buses of APSTC running linked with Doyni Polo Express. Rush down the station , keep ILP handy and board these. Bus fare is Rs 60 per head
Else you only 2 options - at mercy of Taxi walas or hungry mosquitoes. Taxi walas will charge you anything around ₹ 700-1100 even ₹1200
Do not, I Repeat Do not expect any other transport after sunsets or before sunrise, unless you have someone...
more... to pick you up from NHLN.
The road is an uphill with numerous zig zag curves and sloppy sharp turns and prone to landslide and it's effect - traffic jams.
No need to mention no OLA UBER at all.
Some pics of the last night land slide. So 40 mins journey to Itanagar took around 90 mins.
