The Clwydian Range and Dee Valley Area of Outstanding Natural Beauty

The Clwydian Range and Dee Valley AONB is 390 square kilometres of some of the UK’s most wonderful landscapes. From the coastal slopes of Prestatyn Hillside in the North to the remote Berwyn Mountains and the Pontcysyllte Aqueduct and Canal in the South, the Clwydian Range and Dee Valley AONB is a landscape of contrasts waiting to be discovered. The Clwydian Range is a remarkable chain of heather-clad peaks crowned with Iron Age hillforts. To the South, the rolling Llandegla moors give way to the expansive Ruabon Mountain and the spectacular limestone cliffs of the Eglwyseg escarpment. Here the Dee Valley is etched with reminders of a medieval landscape, with the picturesque remains of Castell Dinas Bran, Eliseg’s Pillar and Valle Crucis Abbey and the mighty Chirk Castle which guards the entrance to the valley to the East. The Pontcysyllte Aqueduct and Canal, now a World Heritage Site, is a monument to the AONB’s industrial past.

The AONB falls within parts of the counties of Denbighshire, Flintshire and Wrexham, within easy reach for all parts of the UK, and is uniquely placed for you to discover a rich diversity of landscape, history and culture.

The Clwydian Range was designated by the Secretary of State for Wales in July 1985 under the National Parks and Access to Countryside Act 1949.

In November 2011 the Welsh Government Environment Minister confirmed a southerly extension to include much of the Dee Valley from Corwen to Newbridge.

What is an AONB?

An Area of Outstanding Natural Beauty (AONB) is a designated part of our landscape whose distinctive character, beauty, and cultural heritage are so precious that it is safeguarded in the national interest. Safeguarding is the protection and enhancement of the natural beauty, communities and businesses, and the unique architecture and archaeology of the area.

There are 46 Designated Areas of Outstanding Natural Beauty in the UK, and the Clwydian Range and Dee Valley AONB is one of only 5 in Wales.
