Malltraeth Sands is a picturesque beach located on the southern coast of Anglesey, an island in North Wales. This stunning stretch of golden sand is situated near the village of Malltraeth, which lies at the mouth of the Afon Cefni river.

The beach itself is renowned for its natural beauty and tranquility, attracting visitors from both near and far. It spans approximately two miles in length and offers breathtaking views of the surrounding landscape. The expansive sands are backed by dunes and grassy areas, providing ample space for relaxation and recreational activities.

Malltraeth Sands is a haven for wildlife enthusiasts, as it is designated as a Site of Special Scientific Interest (SSSI) due to its rich biodiversity. Birdwatchers flock to this area to catch glimpses of rare species such as the little tern and the oystercatcher. In addition, the nearby estuary is an important habitat for a variety of wading birds.

The beach is easily accessible, with a car park located nearby and a footpath leading directly onto the sands. During low tide, the sea retreats, revealing vast expanses of sand, perfect for long walks, beachcombing, and picnics. However, visitors should be cautious of the incoming tides, as they can be fast-moving and cut off sections of the beach.

Overall, Malltraeth Sands is a true gem on the Anglesey coastline, offering visitors a peaceful and idyllic beach experience, coupled with the opportunity to admire its natural wonders and diverse wildlife.

Sediments ancient and modern Looking over an outcrop of the Gwna Melange, a metamorphosed sedimentary rock of Cambrian age to the contemporary sediments of the Malltraeth Sands. The Afon Cefni channel can be seen in the middle distance, at approximately low tide. The sea-washed rock outcrop has a thick growth of lichens.

Concretions in sandstone Variable cementing of the sandstone, Carboniferous in age, by carbonates has resulted in irregular weathering and the appearance of large, dark-coloured nodules on the eroded surfaces. The presence of bedding planes passing straight through some nodules is indicative of the structure being secondary in nature. The dark colour is largely due to the slow ablation of the surface compared to less heavily-cemented areas, and the surface is stable enough to be colonised by lichens (yellow Caloplaca is prominent).

Conglomerate beds Beds of a pebble conglomerate dip steadily to the right in this image. It is widely regarded as being a basal formation to the local Carboniferous outcrop, but here its position in the stratigraphy is rather obscure. Similar beds can be found at the side of Lligwy Bay <a href="https://www.geograph.org.uk/gridref/SH5087">SH5087</a> where limestone is also in evidence.

Outcrop of unconformity At the left of this image rocks belonging to the Gwna Melange can be seen. These are of Pre-Cambrian age and significantly metamorphosed. Falling down and spreading over the ancient topography, a rough cliff-like feature, are much younger rocks comprising a scree of angular debris obviously derived from the Gwna Melange. Higher up the succession, to the top right of the image the sediments are more obviously bedded and fine-grained in nature. The younger sediments are widely regarded to be of Devonian age, but may be Carboniferous as there is a lack of diagnostic fossils. A walking stick is stuck into a small thrust fault in the Gwna Melange for scale.
