Dong Valley

Dong Valley is one of the most unique and fascinating destinations in Arunachal Pradesh, located in the Lohit district near the India–China–Myanmar tri-junction. This remote valley is widely known for being among the first places in India to witness the sunrise every day. Surrounded by rugged mountains, pristine rivers, and untouched natural landscapes, Dong Valley offers a rare blend of adventure, geography, and raw natural beauty.

The valley lies at the confluence of the Lohit River and the Sati River, making it not only scenic but also geographically significant. Due to its remote location and limited accessibility, Dong Valley remains largely unexplored, attracting adventure lovers, trekkers, photographers, and travelers who seek offbeat destinations away from crowded tourist spots.
