The mulberry tree is crucial for silk production. Its leaves are the only food for silkworms (Bombyx mori) - and so without a mulberry tree there are no caterpillars, and without a caterpillar there is no silk. The tree was not native to the Drôme, but grew along the roadside. It was deliberately planted at the driveways of houses that bred caterpillars. This kept the routes short and ensured supplies for the beneficial insects. Today, however, there are hardly any trees left in the landscape.

Beautiful trail, almost continuously from Crest to the Rhône. Unfortunately, logically, only as much gradient as a river has.
