Visiting our sites safely
Please take personal responsibility for your safety, making additional preparations ahead of your visit and abiding by the safety measures in place.
From Easter to late August to protect ground nesting birds within the dunes we are requesting that visitors with dogs keep them either on a lead or walking to heel whilst in the dunes. If you wish to let your dog off the lead we recommend the beach on the seaward side of the dunes except for the northerly area which is fenced off for ground nesting ring plovers. In all areas please keep dogs under control and use the dog bins provided.
The Dyfi National Nature Reserve is situated midway between Aberystwyth and Machynlleth.
The 2,000 hectare National Nature Reserve covers three main areas:
The estuary includes vast areas of internationally important mudflats, sandbanks and saltmarsh that provide important feeding and roosting areas for wetland birds.
The superb dunes of Ynyslas are at the southern side of the estuary mouth and are the largest dunes in Ceredigion.
They demonstrate all the stages of dune formation and growth, from sandy shore through vegetated shingle, fore dunes, mobile dunes and fixed dunes to scrub.
They 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.
Cors Fochno lies to the south east of the dunes and the River Leri. It is one of the largest and finest remaining examples of a raised peat bog in Britain.
Its formation started around 5500 BC when part of the estuary floodplain was covered by forest, but as sea levels rose, the forest was replaced by reed swamp and then peat bog. The bog’s surface today is dominated by a tapestry of gold and red sphagnum mosses. The most westerly part is now eroded by the sea, but at low tide the stumps of long dead trees can still be seen on the beach near Borth.
Many rare and unusual species live here including insectivorous plants like sundews, the rosy marsh moth and small red damselfly.
Ynyslas is the main access point to the National Nature Reserve.
The visitor centre and small shop is open Easter until the end of September.
There is a 500 metre boardwalk from the visitor centre across the dunes to the beach and a shell path from the visitor centre to a boardwalk across the dunes to the beach.
There is also a footpath from the caravan park to the shell path where it joins the boardwalk.
The visitor centre has been accredited as a Quality Assured Visitor Attraction by Visit Wales. The Visit Wales Quality Marque is awarded to attractions that have been independently assessed against the national standards of the Visitor Attraction Quality Assurance Scheme.

During the year look out for changes to the landscape and wildlife.
Read on to find out what you could see here during the different seasons.
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:
You might also catch sight of the Greenland white-fronted goose: this is its only locality throughout Wales and England.
