The lower part of this valley does not have roads suitable for cars because of the very mountainous terrain. The upper and middle parts of this valley are served by a few secondary forest roads which connect to the west with route 381. Forestry is the main economic activity in this valley; recreational tourism, second.

The upper part of this river has a freezing period of about one more week. The water level of the river varies with the seasons and the precipitation; the spring flood generally occurs in April.
