Hills, valleys and canals
The Clwydian Range
A chain of heather hills running down the east of the county, with Moel Famau and its Jubilee Tower the best known summit. It forms the Clwydian Range and Dee Valley National Landscape, which was formerly an Area of Outstanding Natural Beauty.
Offa’s Dyke Path
The national trail starts at Prestatyn and follows the Clwydian ridge south, so a short stretch makes an easy day walk from the coast.
Llangollen Canal
Walk or cruise the canal from Llangollen to the Horseshoe Falls. Pontcysyllte Aqueduct, a World Heritage Site, is a short drive away just over the border in Wrexham: see our Cefn Mawr guide.
