Nature Reserve:Morfa Harlech Nature Reserve (NRW)

Nature Reserve, free entry

LL46 2UR



Morfa Harlech sand dunes structures are arguably the most dynamic form of natural habitat in the world. The coastal walk through the reserve is a dramatic and spectacular sweep of untouched golden sand.

At first sight this might appear to be uninteresting as a National Nature Reserve - little but rolling sand dunes covered in marram grass. But it is a genuinely wild place, created by and changing with the forces of nature, not of humans. The dunes here are actively growing with a constant supply of sand being blown inland from the north of Barmouth Bay. The sand accumulates there, having been deposited by the rivers that had washed it down from the mountains of Snowdonia. The land here is rising, not only from accumulation of sand, but because the north west of Britain is gradually rising. When Harlech Castle was built in 1274 it was right on the seashore!

Dunes grow first with sand building up around some obstruction such as seaweed or debris on the shore. Once the embryo dune starts growing, specially adapted plants like marram grass can take hold. This grass is deep rooted and can grow rapidly to keep pace with sand that might smother it.

Further inland the dunes become more vegetated. Other grasses and a variety of plants adapted to the special conditions of vey dry soil and salty atmosphere grow on them.

Morfa Harlech is also a good place for birdwatching, especially in winter when you might see whooper swans and large flocks of wigeon and mallard. Hundreds of curlew and oystercatcher also congregate on the mudflats to the north.
