About this Route

This GPX climbs Moel Siabod from Pont Cyfyng by the old quarry track and Daear Ddu ridge, returning the same way. It covers 9.7 km with about 796 m of ascent and usually takes 5 to 7 hours. Daear Ddu is a Grade 1 scramble: the difficulties can often be varied, but hands-on movement and careful route choice are unavoidable.

From Pont Cyfyng, follow the lane and quarry track uphill past old workings and towards Llyn y Foel. The track gives way to rough, wet ground around the lake. Daear Ddu rises beyond as a broken rocky ridge. Keep to the crest or the easiest worn line, using hands on blocks and short steps. Exposure is limited on the best route but increases if you stray onto steeper flanks. The ridge finishes close to Moel Siabod's 872 m summit shelter and trig point.

Return down Daear Ddu and the quarry track exactly as shown by this GPX. Descending the scramble is harder than climbing it, especially on wet or icy rock. This is not a route for walkers who want to avoid using their hands. Keep the group close, leave space below loose blocks and turn back before the ridge if conditions or confidence are poor.

Daear Ddu is best taken slowly, choosing the easiest rock rather than chasing a single worn line.

Essential Tips

This is a Grade 1 scramble

Hands-on climbing is part of the route. Choose another ascent if anyone is uncomfortable with scrambling.

Descent is the harder direction

Downclimbing Daear Ddu needs time and concentration. Face into awkward steps and keep the group together.

Avoid wet, icy or windy conditions

Slippery rock sharply increases the risk. Turn back at Llyn y Foel if the ridge is unsafe.

Watch loose blocks

Keep space between walkers and never climb directly below someone who may dislodge a stone.
