Aberarth Beach is mostly pebbles and shingle with some patches of coarse sand backed by low cliffs of boulder clay. There are groynes and other sea defences to prevent erosion and at low tide the stone remains of fish traps can be seen. The sandiest part of the shore is to the south of the river (Afon Arth).
Aberarth village is well kept, with narrow lanes and no specific parking areas, but roadside parking can be found. Probably the best place to look is on the roads leading west from the A487 south of the river bridge. There are no toilets or any other facilities here. For surfers this is a beach break at its best around mid to high tide. There are rips to beware of, and underwater rocks can be a hazard, so it's not really suitable for beginners and it tends to be flat in summer.
