Morfa Dyffryn National Nature Reserve, near Barmouth

Welcome

Morfa Dyffryn National Nature Reserve is one of the most important dune systems in Wales because of its bare sand and wildlife habitats.

Dunes like these with bare sand areas are becoming increasingly rare. The wind constantly moves and reshapes the dunes and they provide a home for rare and highly specialised plants and animals.

As well as the huge sand dunes, there are areas of seashore, saltmarsh and grassland and each of these habitats is home to an amazing variety of wildlife.

Together with Morfa Harlech to the south, the two reserves form an almost continuous area of sand dunes along the coastline.

Visiting Morfa Dyffryn

There are two walking routes from the car park on Ffordd Benar through the reserve to the beach.

The wooden boardwalk from the car park goes straight to the beach.

The path from the car park goes through the dune slacks and onto the open beach.

On a clear day enjoy views of the Llŷn Peninsula and a glimpse of Bardsey Island from this stretch of the Cardigan coast.

There is a viewpoint with picnic bench at the beach end of the boardwalk and there are picnic tables in the car park.

Naturist beach

Please note that part of the reserve is a designated naturist beach and is signed accordingly.

Seasonal dog restrictions

Please keep dogs on leads during the bird breeding season March – July; ringed plovers nest right on the beach and other birds nest in the dunes and saltmarsh.

What to see on the National Nature Reserve

Morfa Dyffryn is a National Nature Reserve.

National Nature Reserves are places with some of the very finest examples of wildlife habitats and geological features.

The landscape and wildlife varies depending on which time of year you visit – here’s what to look out for.

Spring

This is a good time to see many of the flowering plants that grow in the dune grasslands and slacks.

Several nationally rare and scarce wildflowers, lichens and mosses make their home here. The wild orchids include the lovely marsh helleborine which grows alongside the northern marsh-orchid as well as the early marsh-orchid.

There is a whole host of other brightly coloured wildflowers to enjoy from early spring onwards. Thrift and common centaury put in an early appearance and they are soon followed by other coastal species including common restharrow, wild pansies, bird's-foot trefoil and many others.

You might also come across sea mouse-ear, thyme-leaved sandwort, portland spurge and dune fescue.

Lapwing nest here and ringed plovers breed on areas of shingle.

Summer

In the warmer months, a wide variety of flowering plants can be seen in the dune grasslands and slacks. These include dune pansy, speedwells, thyme, maiden pink and orchids.

There are also colonies of the rather scarce green-flowered helleborine and round leaved wintergreen - July or August is the best time to see this species.

Summer is also a busy time for many invertebrates including mining bees and beetles.

Look out for the small copper, peacock, and gatekeeper butterflies and day-flying moths such as the cinnabar and forester.

Autumn

The drier dune grasslands are well known as good habitat for fungi and the dunes here offer impressive fungi 'vistas'.

Dwarf earthstar occurs only in mature dune grasslands such as those found at Morfa Dyffryn.

You may also see multi-coloured waxcaps, coral and club fungi, earthtongues and parasols.

Winter

The sand flats and salt marsh in the estuary are important feeding grounds for winter wildfowl.

The beach is used by wading birds but, if you look offshore, you may spot wintering grebes and divers.

Other bird species that put in an appearance at the reserve in winter include choughs and hen harriers.
