Its source lies in the hills of southernmost Flintshire to the east of Rhydtalog village. It flows in a roughly north-easterly direction before turning south-east through the villages of Llanfynydd and Ffrith where the Nant-y-Ffrith stream flows into it. It then heads north-east again through a wooded valley before joining the River Alyn at Cefn-y-bedd.

The name of the river indicates a place where hemlock grows.^[1]
