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 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.
