Moelwyn Mawr

This is a hillwalk, not a roadside viewpoint. A direct route from Croesor village uses old quarry tracks and rough mountain paths to reach the ridge. Typical versions are about 10 km with roughly 700 metres of ascent and take 3–4 hours; longer circuits that add Moelwyn Bach, Rhosydd Quarry, and Cnicht can run to 15–16 km and most of a day. Expect steep, rocky, and sometimes boggy ground, with a short scrambly section around Craigysgafn and limited waymarking.

The summit itself is a rewarding place to pause: a slate-built triangulation pillar sits among loose slate and grass, with Llyn Stwlan and the Moelwynion spread around it. The surrounding quarry remains and old tramway approaches give the walk more texture than a bare summit ascent.

• Bring a map and compass, and know how to use them. Paths can be faint, especially in mist.
• Wear hiking boots, waterproofs, and warm spare layers. Carry enough food and water for a full mountain outing.
• Keep dogs on a lead where the route crosses agricultural land, and use only designated parking in Croesor without blocking homes, field entrances, or narrow roads.
• This is best for walkers with suitable fitness, navigation skills, and experience on rough upland terrain. Turn around if the conditions or your group’s ability no longer fit the route.
