Many people have mentioned that there was at one time a crossing place across the Burry Estuary. Wynford Vaughan Thomas recorded the following in his book Portrait of Gower.
In the old days, before they dredged the channel up to Llanelli, it was possible to cross the estuary by a path through the sands. John Wesley was guided across it from Pembrey when he came to Gower. It was a tricky way through sand-banks and quick-sands an Wesley was thankful to reach the Gower shore safely. Today we would be utterly unwise to attempt such a thing. The tide comes in swiftly and you can find yourself isolated on an ever-decreasing bank of sand before you know where you are.
