Aeyo Valley: Arunachal Pradesh's Best-Kept Secret

Aeyo Valley: Arunachal Pradesh's Best-Kept Secret 


Not long ago, a single hunter armed with an air gun could bring down 50-60 birds in a day across these hills. Nobody questioned it — until the harvests did. Corn yields kept falling, year after year, and the valley's people finally traced it back to the very birds they'd been hunting out of the sky.

So the community did something rare: they sat down, talked it out, and chose change. Commercial hunting was scaled back to sustainable, subsistence levels — and in its place rose two new paths: farming and tourism.

Today, the forests that once echoed with gunfire echo with the footsteps of trekkers instead. What was once a hunting ground has quietly become one of the Himalayas' best-kept secrets — and the story doesn't end there.

While the world chases Manali and Leh, Aeyo Valley in Arunachal Pradesh has spent centuries perfecting the art of staying hidden — and it's nothing short of breathtaking.
