Cardigan Bay is home to Europe’s largest population of bottlenose dolphins which like the atlantic seals are often visible from the beach and cliffs at Cwmtydu. A number of seals pup on Cwmtydu beach every year.
As well as the sea birds, seals, and dolphins, the Wildlife Trust of South Wales lists 20 nature reserves in Ceredigion with a wide variety if habitats, from ancient woodland and grasslands to lakes and islands. These offer sightings of many other species including birds, rare plants, and insects.
One of the few sites in Wales to see the pearl bordered fritillery butterfly is on the next valley up the coast from Cwmtydu. The walk of about three miles takes in a short stretch of the coast path, an ancient settlement at Castel Back and an excellent secluded beach at Nanternis.
