We travelled in Anjaw, Lohit and Changlang district of Arunachal for 15 days in the month of October. All the places we stayed at, were government-run with basic accommodation; this website on travelling to Changlang is helpful.
All places on Google Maps. Dibrugarh, Namdapha National Park, Nampong (Pangsau Pass & Stillwell road), Myanmar (Lake of no return), Jairampur (World War 2 Cemetery), Wakro, Golden Pagoda, Parshuram Kund, Hawai, Walong (Namti Plains, Helmet top and hot springs), and Kibithu - easternmost town in India on the LAC - Line of Actual Control, with China. Indian nationals require Inner Line Permits to visit.
P.S. Carry your binoculars to increase chances of spotting wildlife, and swimming gear as you'll be next to a stream of river, mostly. Insect & mosquito repellents are a must. And as a responsible traveler, I ask you to help keep the beauty of this place as it is now, untouched! Thankyou and Happy Travels! :)
