74 miles of stunning coastline

You couldn’t have a more varied and dramatic landscape than Eryri’s.

The National Park is home to 74 miles of spectacular coastline, with beaches and shores as breathtaking as the mountains and forests.

There are very few places in the world where it is possible to experience such a wide variety of environments within such a short distance.

The beautiful Dyfi, Mawddach and Dwyryd estuaries, together with the spectacular coastline and sandy beaches, contribute to Eryri’s wide variety of landscapes.

Morfa Harlech Sand Dunes

The dune system at Morfa Harlech is one of the most important dune systems in Britain and one of only a handful in Wales.

Such areas are becoming increasingly rare.

It is one of Wales’ richest natural treasures and is home to a wide variety of wildlife that has evolved specifically to live in such a habitat.

Along with Morfa Dyffryn in the south, the dune system has been designated a National Nature Reserve and areas of the beach have been designated Sites of Special Scientific Interest.
