Diffwys

Diffwys is a mountain within the Rhinogydd range in Gwynedd, rising to 750 meters with a trig point at its summit. The peak overlooks the surrounding terrain and sits among other heights that make up this rugged hill country.

The mountain is composed of sedimentary rocks from the Paleozoic era, representing millions of years of geological history in Wales. These rock formations tell the story of how this landscape took shape over vast stretches of time.

Local mountaineering groups maintain regular routes across Diffwys, establishing traditions of responsible climbing and environmental protection practices.

The best time to visit is between May and September when the weather is most stable for mountain walking. Access is by way of established trails and parking areas nearby, which follow local path systems and markers.

The summit falls just 2 meters short of reaching Marilyn status, a specific classification within British mountain categories. This narrow miss has made it a memorable target for some mountain hikers who track such distinctions.
