The large sweep of the pebbled Tanybwlch beach is to the south of the harbour at Aberystwyth and is overlooked by the imposing Iron Age hill fort, Pen Dinas with its prominent memorial in the shape of an upturned canon that commemorates Wellington’s victory at the battle of Waterloo in 1815. Pen Dinas and neighbouring Tanybwlch beach have been a local nature reserve since 1999. A climb up to the top of Pen Dinas on a pleasant day is very rewarding – you can see for miles inland along both the Ystwyth and Rheidol river valleys, as well as out to sea. Parking. Dogs allowed.
