Llansteffan Beach (Llanstephan / Tywi Estuary)

This lovely beach is situated on the western side of the Tywi / Towy Estuary. I say it is a beach but apparently the tourist board won’t call it one and insist it is referred to as an estuary. Well, if it looks like beach, feels like a beach and smells like one, then in my books it is a beach!

The sand here is fine and golden, becoming much firmer towards the sea - ideal for sandcastles. Llansteffan beach’s main stretch is backed by a flat grassy area with picnic benches and children’s play park. Along with plenty of facilities close at hand, Llanstephan is a great family beach.

The only drawback with this beach is that swimming is considered dangerous, particularly along the stretch of beach further up the estuary. It is also worth pointing out that you should not attempt to cross the estuary, even at low tide.

Llansteffan beach is overlooked to the west by the ruins of the Norman Llansteffan Castle. You can climb the one remaining tower from which the views of the beach and estuary are great.

Had a chalet here for many years at the extreme Northern end .It’s a superb beach for walking at any time of the year with the cliff path providing a convenient walkway   when the tide is up ,swimmers do need to be aware of the estuary tides though with a strong river current   .At low tide you can get to Wharley point which is a National Trust headland with interesting caves and a view around to the adjoining estuary at Dylan Thomas’ Laugharne .The view from the castle is also amazing especially when the tide is out and the sand flats stretch for miles across to Pembrey .In fact I feel the need to get up and go there again as soon as possible .

What did we get wrong?
