, in the
Clwydian Range and Dee Valley AONB. Five National Landscapes, or Areas of Outstanding Natural Beauty (AONB), have been designated in Wales, one of which, the Wye Valley National Landscape, straddles the
Anglo-Welsh border. The areas are: •
Gower National Landscape () – which spans of the
Gower peninsula. The AONB covers almost the entire
peninsula (excluding some eastern urban areas), and is located within the
City and County of Swansea on the
south-west coast of Wales, on the north side of the
Bristol Channel. Referred to colloquially as "the Gower", it was the first area in the United Kingdom to be designated as an AONB in 1956. •
Llŷn AONB () – which spans or around a quarter of the
Llŷn Peninsula, covering much of the coastline and the ex-volcanic hills. The peninsula extends into the
Irish Sea from mainland
north-west Wales, and south-west of the
Isle of Anglesey. The AONB was created in 1956, and is one of the most scientifically important in both Wales and the United Kingdom. of the AONB's coastline is
Heritage coast. •
Anglesey AONB () – which was designated as a AONB in 1966, in order to protect the aesthetic appeal and variety of the island's coastal landscape and habitats from inappropriate development. The AONB covers most of Anglesey's coastline, as well as inland areas, such as
Holyhead Mountain and
Mynydd Bodafon. The AONB covers around , about a third of the
county, making it Wales' second-largest AONB, and largest until 2011. It is one of the most dramatic and scenic landscape areas in
Southern Britain. The
River Wye () is the
fifth-longest river in the United Kingdom. The upper part of the river passes through the settlements of
Rhayader,
Builth Wells and
Hay-on-Wye, but the area designated as an AONB surrounds only the 58-mile stretch lower down the river, The AONB is in land area, increasing from before 2011, and it is also a
proposed national park.
Proposed areas , in the proposed
Ceiriog Valley, from the bridge at
Llanarmon Dyffryn Ceiriog. •
Cambrian Mountains — launched in November 2006, the campaign by Cambrian Mountains Society to make the area an AONB, campaign on the basis that AONB status would "boost the local economy, and help agriculture, heritage and culture". The area's bid to become a national park has been in the works since the 1960s, reaching the
Welsh Office in 1973, where it was ultimately rejected. The campaign continues to propose that the area should become a national park, advocating for any type of environmental protection for the area. Welsh ministers expressed openness to the idea in 2023, however progress on the bid would be delayed to 2026 as ministers focus on a Clwydian Range and Dee Valley national park. •
Ceiriog Valley and
Y Berwyn — The
Countryside Council for Wales (CCW) started the consideration of the area into an AONB in February 2011 alongside proposals for the then
Clwydian Range AONB. A final report published in March 2012, concluded that AONB status for Y Berwyn (which includes the Ceiriog Valley) is "desirable for the statutory purpose of conserving and enhancing the area’s natural beauty", but further work is to be done by the CCW to investigate alternatives to AONB status before a final decision is to be made. • Expansion of the Gower AONB — first proposed in 2005, the Gower Society calls for an extension of the Gower AONB, and submitted a proposal to the
National Assembly for Wales in March 2012. The Gower Society have also proposed for the AONB to become a national park, however such proposals have not been acted on by the Welsh Assembly Government. •
Gwent Levels — In July 2019,
John Griffiths AM for
Newport East called for the area to be awarded AONB status following the scrapping of the
proposed M4 relief road, which if followed through would've passed through the proposed area. Griffiths states that AONB status would protect the area from similar proposals. The Gwent branch of the
Wales Green Party sponsored a petition to make the area an AONB. •
Towy Valley (Tywi Valley) – In April 2023, the Carmarthenshire Residents Action Group launched a campaign for the Towy Valley to become an AONB to protect the area from "harmful developments", with proposed
electricity pylons used as an example. •
Mid Wales – In April 2023, a petition was launched for a
Mid Wales AONB covering the Upper Wye Valley and the water catchment areas of at least the rivers
Irfon,
Ithon and
Elan.
