Morfa Harlech National Nature Reserve is a coastal landscape of unrivalled beauty and variety. 

The whole area can be read as a vivid textbook on how our coastline has developed over the centuries and as a reminder of how precious and fragile such landscapes are.

The dunes at Morfa Harlech

The vast dune system is of international importance. 

It is the only system in Wales which is still growing, and where you will find every variation of dune habitat, together with all the different kinds of wildlife that make their home there. 

It is a shifting, changing environment, and man has had no small part to play in its history. 

In the Middle Ages, ships could sail up to the foot of Harlech Castle and, even until the 19th century, much of the Morfa was tidal marsh.

The construction of a sea wall helped create the rough pasture here today.

Wildlife at Morfa Harlech

Spring and summer are the best times to see many of the flowering plants that make the dune grasslands and slacks their home.

The sand dune habitat supports several species. These include a rare mining bee and reptiles such as the common lizard and the much rarer sand lizard which was recently re-introduced to the area.

The sand flats and salt marsh in the estuary are important feeding grounds for winter wildfowl while otters and water voles use the estuary’s waterways. 

Visiting Morfa Harlech

There are public footpaths from Min y Don car park to the shore. 

There are public toilets in Min y Don car park which are run by Gwynedd Council.

Parts of the reserve are fenced off to allow controlled grazing and to protect the specialist sand dune vegetation. Download more information about the trails.
