The Acheron River is a remote Marlborough river that flows south from its headwaters near the Acheron Saddle through Molesworth to its confluence with the Clarence. Due to its entire course being within the Molesworth area, with only seasonal road access, the river is less well known than the other major Marlborough rivers, however with a normal flow with a range between 10-20cu m/s (source: NIWA) the river is of similar size to the Awatere.
Two suspension bridges cross the river including the historic Lower Acheron Suspension Bridge, built in 1945 by students from Canterbury University.
The river has small numbers of brown trout which may reach substantial size.
