Former landfill site in Llangollen opens to visitors after being transformed into nature reserve A former landfill site on the outskirts of Llangollen has taken on a new lease of life. Denbighshire Council and the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty team have worked together to create a new nature reserve at Wenffrwd. Visitors are now able to explore the new site by following the 0.5 miles of newly surfaced path which winds through a variety of habitats and offers views of the River Dee and across the valley. The transformation was made possible by funding from the National Lottery Heritage Fund and European Rural Development Fund.
