Overview
The Sheehy Mountains (Irish: Cnoic na Seithe, “Hills of the animal hides”) form a low‑lying, rugged range that marks the border between County Cork and County Kerry in the southwest of Ireland. Geologically they consist mainly of Old Red Sandstone laid down in the Devonian period and were later sculpted by Ice‑Age glaciers into deep valleys, rounded summits and hundreds of small lakes. The highest point, Knockboy (Cnoc Buí – “yellow hill”), reaches 706 m and is the highest mountain in County Cork. Other notable peaks include Caoinkeen (692 m), Knocknamanagh (637 m) and Gullaba Hill (625 m). The River Lee is born in the Coomroe valley on the eastern edge of the range before winding eastward to Cork Harbour.
History
Human activity in the Sheehys stretches back at least 5,000 years. The foothills and valleys are dotted with Neolithic megalithic monuments, ringforts and fulacht faí cooking pits, testifying to a long agricultural tradition. In the 6th century Saint Finbarr founded a hermitage on an island in what is now Gougane Barra lake; the tiny St Finbarr’s Oratory remains a pilgrimage site.
The range also forms a historic barrier between two cultural zones. The Cousane Gap – a road cut through the mountains in the late 1820s by Sir Richard Griffith – links Cork to Bantry Bay and created the Pass of Keimineigh, a natural mountain pass that separates the baronies of Carbery, Bantry and West Muskerry. During the Irish War of Independence and the subsequent Civil War the mountains served as a stronghold for IRA and anti‑Treaty forces, adding a modern layer to the landscape’s rich heritage.
A small but noteworthy monument to Máire Buí NíLaoighre stands near the entrance to Gougane Barra, commemorating a local heroine whose story is part of the area’s oral tradition.
What to See & Do
Summit hunting – Shehy Mountains Challenge
Experienced hill‑walkers can attempt the four‑summit challenge in a single day, tackling Knockboy, Caoinkeen, Knocknamanagh and Gullaba Hill. Completion between May and August earns a Certificate of Completion and points toward the Irish Challenge Hillwalker of the Year. Registration is open year‑round via the High Point Ireland entry form; summits can be logged with the Peakhunter app.
Knockboy (706 m)
As the highest point in County Cork, Knockboy offers panoramic views over both Cork and Kerry. The ascent and descent typically take 3–4 hours and provide a rewarding finish for hill‑walkers.
Gougane Barra Forest Park – Visitor Details
Gougane Barra Forest Park covers about 340 acres (≈ 137 ha) of pine woodland surrounding a tranquil lake. The park is accessed via a small electronic barrier; vehicle entry costs €5 (coins only), while pedestrians may enter free of charge after a short 10‑15 minute walk from the lake shore.

The island‑situated St Finbarr’s Oratory provides a photogenic backdrop; the gate to the island is usually unlocked, but visitors should check before entering. Nearby parking is available at the Gougane Barra Hotel and Cronin’s Bar & Café. Picnic tables, toilets and a small café (open weekends in summer) are provided.
Shehy Highland Park
Located about 4 km from the scenic Cousane Gap, this working sheep farm doubles as an outdoor heritage site. Three family‑friendly walking trails wind through mixed woodland and open hill terrain, passing standing stones, a bullaun stone and the remnants of ancient hut circles. Walks typically last 2–3 hours and include picnic spots with views of peat‑bogs, heather and bilberry‑laden slopes.
Flora, Fauna & Photography
The mountains are cloaked in peat bogs, coarse grassland and scattered conifer plantations. Botanists may spot butterworts, sundews, heather and bilberry, while wildlife watchers can see Irish hares, ravens, European stonechats, deer, foxes and rabbits. The area’s varied terrain and reflective lake make it a favourite spot for landscape photographers – especially in the early morning or after a light rain when the lake mirrors the surrounding peaks.
Nearby Points of Interest
- Barley Lake – a small, tranquil lake a short detour north of the main road, popular for quiet walks and photography.
- Cousane Gap – the historic mountain pass built in the 1820s, offering dramatic road‑side views and narrow tunnels that add a sense of adventure to a scenic drive.
