Aberystwyth South Beach is a gently sloping beach of coarse grey, gravelly sand reaching from the harbour wall at the southern end to the castle at the other. It is backed by a promenade with P&D car parking, cycle stands, toilets with disabled facilities and showers. A dog ban operates between Castle Headland and the first groyne at the end of South Marine Terrace, from 1st May to 30th September. RNLI lifeguards patrol from early July until early September.
The main town with its facilities is just a short walk away, and fishing trips operate from the harbour in the summer. Aberystwyth rail station is about ½ mile away. Surfers will find a good reef break known as the Harbour Trap at the southern end of the beach. This works best between low and mid-tide with an offshore wind, but there are rips from the rivers Rheidol and Ystwyth which emerge here.
