The whole Reserve is made up of three parts: Cors Fochno, an internationally important peat bog; Dyfi Estuary, an internationally important feeding ground for thousands of wading birds and the beach and sand dunes of Ynyslas, enjoyed by around quarter of a million people every year.
Ynyslas dunes are remarkable. They are still growing, day by day, millimetre by millimetre, providing a home for many rare plants and insects. When you visit, you can see the process taking place. Earth, sea and wind in action. In the summer, the sand dunes are transformed into a colourful carpet of wild flowers and are especially renowned for their rare orchids. And then there's the submerged forest ... the remains of tree trunks which appear at low tide, from the days when the shingle ridge was further out to sea. This could be part of the inspiration for the famous story of the lost land of Cantre'r Gwaelod.
Birds to see...... Stonechats, linnets and larks can be found in the older dunes. Listen for the larks' stream of notes high up in the air. The estuary is home to many wading birds - the shelduck, with its bright green head and chestnut patch on its chest is amongst the most colourful. Parts of the dunes may be roped off in spring and early summer to protect rare ring plover eggs, which are laid directly on the sand.
When you look out to sea, you may see dolphins and porpoise, just some of the fascinating beach. There are four walking trails around this nature reserve
