The Carabosse River is a tributary of the Path River. It has its spring in the Hungry Mountains south-west of Lake Raiteso and meanders its course in a south-westerly direction for about 70 miles. For almost its entire length, the Carabosse acts as the border between the Ustalavic counties of Amaans and Caliphas. Only in its final few miles before flowing into the Path does the river become the border between Caliphas and blighted county of Virlych, at which stage it has the Ebonwood forest on its western bank. It joins the Path River north of the settlement of Hallein Town in Lastwall.
