Dana used to be an old customs point during the days of the salt trade.
Merchants would bring salt from the Tibetan lakes along with goods like yak-
tail, medicinal plants, ghee, and musk. From the lowlands would come the much-
needed grains. And it was at Dana that all the customs duties were paid to the
Thakalis who would then pay an annual tribute to Kathmandu. The monopoly that
the Thakalis of Tukuche enjoyed over the trade that occurred over this route
was the single most important reason for their rise to economic power in the
region and beyond.
Also according to many sources, the gorge at Dana is the deepest in the world.
And while many will tell you that it is true, the Guinness Book begs to
differ, giving the title to a gorge in Greece. The gorge here at Dana between
the massive mountains of Annapurna and Dhaulagiri is indeed very deep, but
given the topography, it might not qualify as a true gorge.
