Aber Bach (also known as Aber Hesgwm) is a pebbly shingle beach with rocks either end. It fishes onto patchy mixed ground.

Fish caught include bass, pollack.

From the A487 between Fishguard and St. David’s, follow the brown signs to Melin Wlan Tregwynt (Tregwynt Woollen Mill). Continue past the mill to a T-junction, where turn left. Very shortly, take the lane on the right, which leads to a parking area above Aber Mawr beach. A short walk north leads to Aber Bach.
