Clwyd covers the north-east corner of Wales, and its real advantage for a buyer is location: it sits right against the Cheshire and Shropshire border, with good road links (the A55 and A483 corridor) making it genuinely easy to reach from north-west England as well as from the rest of north Wales. That border position means you often get Welsh pony breeding with English-county convenience.
The land ranges from the Clwydian Hills, which produce hardier hill-bred ponies, down to gentler, more fertile ground near the Dee valley, which tends to suit better-grown Welsh sections and cobs. Because it draws buyers from both England and Wales, a genuinely good pony here does not sit around for long — decide quickly if you find one you like, and be ready to travel to view promptly.
