Near the mouth of the River Teifi, on the southern side opposite Cardigan, stands St Dogmaels. It is essentially a seafaring village, as examination of headstones in the churchyard will testify. The remains of an Abbey founded by Robert Fitz-Martin in the 12th century are worth a visit. Poppit Sands a little further down the estuary has a beautiful and extensive beach which denotes the start (or the end!) of the 186-mile Pembrokeshire Coast Path.
