Knockomagh

About Knockomagh

Rising steeply above the salt-water rapids of Lough Hyne near Skibbereen, this wooded Marilyn offers an exceptional vantage point over Ireland's first Marine Nature Reserve. The ascent through ancient sessile oak leads to a summit panorama of the West Cork coastline, the Atlantic, and the distant silhouettes of Roaringwater Bay’s islands.

Key Statistics

Did You Know?

• •The name originates from the Irish 'Cnoc na Máighe', meaning 'hill of the plain'. Despite its modest height, its isolation gives it enough prominence to be classified as a Marilyn.
• •Much of the hill is protected within Knockomagh Wood National Nature Reserve, home to ancient sessile oak, hazel, and holly. It represents a rare fragment of the native woodland that once covered the West Cork coastline.
• •The summit provides a perfect bird's-eye view of Lough Hyne’s unique geography, including 'The Rapids'—a narrow channel where the tide rushes in and out, creating a unique salt-water habitat.
• •On the shoreline below the hill’s western slopes lie the ruins of Raheen Castle, a 15th-century tower house once belonging to the O’Driscoll clan, who dominated the waters of Roaringwater Bay.
• •The standard ascent follows a zig-zagging forest trail from the lough-side car park, a route that manages to feel surprisingly alpine despite the hill's proximity to the sea.
• •While the climb is short, the humidity and steep gradient through the dense canopy ensure that most hikers arrive at the summit looking considerably more weathered than a 197-metre elevation suggests.
