Formerly known as Along, the town of Aalo functions as the headquarters of the West Siang district in Arunachal Pradesh. Lying close to several tiny villages, this small town is situated at the congregation of the two rivers of Sipu and Yomgo. Mechuka Valley, among the most beautiful offbeat places to visit, can be visited from Aalo to which it is well connected via road. With blooming orchards of oranges in and pleasant cum cool weather, Aalo is best visited in the winter season.

Aalo and its surrounding region cater to both adrenaline junkies and peace-seekers alike. On one hand, activities like trekking and river rafting are quite popular here. The surrounding terrain of rocky river banks and jungle cutting through the valley make for excellent hikes.
