|Route outline (key)|
The B4342 is a long B-road in Cardiganshire.
It starts on the coast at New Quay, as a continuous road with the A486. It then heads south eastwards via Gilfachreda to reach the A487 at Llanarth. There is a multiplex north through the village before the B4342 turns off to the right and regains its number.
The road TOTSOs right less than half a mile further on before continuing southeast to Mydroilyn then east to Dihewyd. Here there is a sharp bend to the right at the junction with the B4339. Continuing east the B4342 descends into the valley of the River Aeron and reaches the village of Ystrad Aeron. The road meets the A482 at a T-junction and multiplexes south into the next village, Felinfach.
The road regains its number and its easterly direction only for about a mile. At the next T-junction it meets the B4337 and multiplexes north over the river and into Tal-sarn where the multiplex ends and our road heads east once more.
The B4342 then follows the valley of the Aeron upstream for over five miles to Llangeitho, where it crosses the river. There is a most unexpected roundabout in the centre of the village, after which the road climbs out of the valley to Stags Head, where it is crossed by the B4578. The road now descends into the Teifi Valley where it ends on the A485 at Trecerfel, about a mile south of Tregaron.
