It is located roughly 800 feet (240 m) over water level at the eastern end of the Preseli Mountains. It stands astride the old Tenby to Cardigan turnpike road, currently the A478. The town developed around the former Crymmych Arms train station on the now-closed Whitland to Cardigan Railway, nicknamed Cardi Bach (Little Cardi). Crymych, which is twinned with Plomelin in Brittany, has a chosen community council. The town has provided its name to a selecting ward of Pembrokeshire that encompasses the villages of Crymych itself and Eglwyswrw.
