Foel Ddu

About Foel Ddu

Rising above the northern edge of the Wnion valley, this modest Hump offers a quiet, grassy ascent away from the busier trails of the main range. Characterised by its dark, rounded profile, the summit provides an excellent vantage point overlooking the rugged terrain that bridges the gap between Cadair Idris and the Arans.

Key Statistics

Did You Know?

• •The name stems from the Welsh 'Foel', meaning a bare or bald hill, and 'Ddu', meaning black or dark, likely referring to the dense heather or peat hags that cover its upper slopes.
• •The summit offers a clear, unobstructed perspective across the valley to the massive northern escarpment of Cadair Idris and the distinctive, craggy profile of Rhobell Fawr to the north.
• •Walkers often approach from the lanes near Dolgellau, using the hill as a quieter alternative to the more famous peaks nearby, frequently enjoying the summit in total solitude.
• •Its classification as a Hump—a hill with at least 100 metres of prominence—ensures it feels like a distinct and independent peak despite its relatively low elevation.
• •The lack of a defined path through the thick heather means that in poor visibility, the 'Black Hill' requires a level of navigational focus usually reserved for much higher mountains.
