The valley runs inland at a perpendicular angle from the coast along a bearing of 45° (northeast), carrying the Codroy River and its tributaries to the gulf.
The mouth of the Codroy Valley at the coast is extremely windy and is the location of Wreckhouse, so-named by employees of the historic Newfoundland Railway for the wind's ability to blow railway cars off the tracks.
The area was settled families of French, Irish, Mi'kmaq, English, and Scots.
The Scots were Highlanders who arrived between the 1840s and 1860s, most of them secondary migrants who had been living on Cape Breton Island in Inverness County, Nova Scotia.
