Dyfi Ynyslas Visitor Centre and Nature Reserve

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

The visitor centre is open Easter until the end of September. It has a small shop and toilets, and sells hot and cold drinks and snacks.

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.
