Aber Tywi, also known as the Mouth of the River Tywi or the Tywi Estuary, is a geographical feature located in South Wales. It is where the River Tywi (or Towy) empties into the Bristol Channel.
Here Arthur and his men fought one of several battles against the boar Twrch Trwyth, and the warriors Cynan and Gwilenhin were slain. From here, the chase moved on to Glynn Ystun.
