Natural wonders in Wales

Wales' landscape is defined by its geological diversity, featuring the highest peaks of the Brecon Beacons, such as Pen y Fan, and extensive cave systems like the 17-kilometre Dan-Yr-Ogof. The region contains glacial lakes like Llyn Tegid and Victorian engineering projects like the Cardiff Bay Barrage and Lake Vyrnwy. Coastal highlights include the limestone cliffs of the Gower Peninsula and the Llŷn Peninsula's secluded waterfalls. From the raised bogs of Cors Caron to the cascading falls of the River Mellte, these sites showcase the country’s varied upland and aquatic environments.
