Dyfi National Nature Reserve - Ynyslas Visitor Centre, near Aberystwyth

What's here

Please check the Ynyslas Facebook page for the latest information.


Ynyslas is part of the Dyfi National Nature Reserve, situated midway between Aberystwyth and Machynlleth.

The superb dunes of Ynyslas are at the southern side of the Dyfi Estuary and are the largest dunes in Ceredigion.

The estuary has vast areas of internationally important mudflats, sandbanks and saltmarsh that provide feeding and roosting areas for wetland birds.

There are far-reaching views over the estuary towards Aberdyfi but, even though this town looks so close, it is a 45 minute drive around the estuary from Ynyslas.

Explore the dunes, beach and seashore on the walking trails from the car park or simply follow your nose and take in the wide open spaces, spectacular views and the sounds of wind, sea and birds.

Ynyslas Visitor Centre

The visitor centre is the ideal place to start your visit.

It has an exhibition about what to see at the reserve, and a shop selling hot and cold drinks, snacks, books and local produce.

What to see at the National Nature Reserve

Ynyslas is part of the Dyfi National Nature Reserve.

This 2,000 hectare reserve also includes the Dyfi estuary and Cors Fochno.

Ynyslas dunes demonstrate all the stages of dune formation and growth and are home to a rich population of orchids, mosses, liverworts, fungi, insects and spiders; many of these species are rare and some are unknown elsewhere in Britain.

The landscape and wildlife varies at Ynyslas depending on which time of year you visit – read on to find out what to look out for.


As the weather warms up, there are spring flowers in the dunes and flowering cotton grass on the raised bog.

You may catch a glimpse of one of the many reptiles that live here such as the common lizard, sand lizard, adder and grass snake. The Welsh vernal mining bee is also active during the spring.

There is plenty of birdsong to enjoy, too, from the likes of skylarks, linnets, chiffchaffs and willow warbler. In the evening, nightjars can be heard.


Summer brings a varied display of flowers to the reserve. Marsh and bee orchids appear in the early summer in the dune slacks (the wet areas of the dunes) followed by pyramidal orchids. There are also colourful saltmarsh flowers, sea pink, sea aster, sea spurrey and, in late summer, marsh helleborine.

Butterflies and day-flying moths fill the air, while dragonflies dart around the raised bog.

You might spot wildlife like osprey and otter on the estuary.


The autumn colours are rich and varied on the raised bog which is dressed in a range of russet red colours.

Fungi including waxcaps, earth stars, puffballs and bird’s nest fungi add to the colourful display.

Migrating waders can be seen in the estuary.


During the winter months, the Dyfi estuary is home to wintering wildfowl while, on the beach, you may see waders, sanderling and golden plover.

Keep your eyes peeled for hunting birds of prey over the bog. Look out for:

  • red kites
  • buzzards
  • hen harriers
  • merlins
  • peregrine falcons

You might also catch sight of the Greenland white-fronted goose: this is its only locality throughout Wales and England.
