The town is situated near the confluence of the rivers Ystwyth and Rheidol, on the west coast of Wales. Although the name may seem to suggest  otherwise, only the River Rheidol passes through the town; following the reconstruction of the harbour, the River Ystwyth skirts the town. Aberystwyth has a pier and a fine seafront which stretches from Constitution Hill at the north end of the Promenade to the mouth of the harbour at the  south, taking in two separate beach stretches divided by the castle.  Today it is essentially made up by a number of different areas:  Aberystwyth town, Llanbadarn Fawr, Waunfawr, Penparcau, Llanbadarn and Trefechan, with Penparcau being the most populous.
