Mochras

Mochras is a peninsula lying west of Llanbedr in Gwynedd, Wales. The peninsula was formed after the River Artro was diverted by the Earl of Winchilsea in 1819 from its previous course where it entered the sea to the south of Mochras. Prior to this, access to the ancient settlement on the 'island' would have been through the village of Llandanwg, which is now across the estuary.

Mochras is known for the wide variety of seashells that wash up on the beach, and for its wild flowers. It is said to have been connected to the mythical Cantre'r Gwaelod.
The peninsula lies within the Snowdonia National Park. From the end of October to the following March local farmers bring their sheep from the lowlands to graze on the 'island'.

Geology

Mochras is significant for the UK earth sciences. The area consists of a low lying raised beach.
Between 1967 and 1969 the British [Geological Survey|Institute of Geological Sciences] drilled a 1,938 m stratigraphic proving borehole at Mochras Farm. This found relatively young Tertiary and Mesozoic rocks, faulted against the ancient Cambrian rocks of the Harlech dome. In 1971, the vertical throw of the fault was judged to be at least.

Access

Public vehicular access to the peninsula is only possible via a causeway across the estuary of the River Artro when the tide is out. Access on foot is always possible from the adjacent Morfa Dyffryn beach, which extends for several kilometres south of Mochras. Access to emergency vehicles is available at any time through the neighbouring airfield.

Amenities

Mochras has a popular camp site which offers the opportunity to practise "wild camping" in pitches which are far from the nearest neighbour. Camp fires are allowed on the beach; with only raised, contained fires and barbecues allowed on the campsite.
