Overview
Caoinkeen is the second-highest point in County Cork, and the reason to climb it is the north-east face: a near-vertical headwall dropping into a corrie lake, an almost impenetrable wall of rock. The Irish name An Caincín means ‘snub nose’ or ‘turned-up nose’, and it fits the ridge running north from Knockboy, which is cut off abruptly in that cliff. At 692.8 m (2,273 ft) Caoinkeen is the 123rd-highest mountain in Ireland and the second-highest in the West Cork Mountains, listed as an Arderin and a Vandeleur-Lynam, and included in the Irish Highest Hundred. The summit itself is a broad, rocky top overlooking the corrie lake, not a dramatic point.
Name & history
The bedrock here is purple and green sandstone and siltstone, part of the Caha Mountain Formation, and glaciation during the last Ice Age did the rest of the work, scouring out the corrie and its cliffs and leaving peat-covered hollows across the plateau. Historically the upland was used for seasonal transhumance grazing. The summit cairn likely began as a territorial marker, helping shepherds move livestock between summer high pastures and winter lowland fields, and it has since served as a quiet waypoint for walkers.
Walking routes
There are two main approaches, depending on where you start and how long you want to be on the hill. Neither is waymarked on the upper ground, so this is a day for map, compass and confidence in bad visibility.
The Priests Leap approach (shorter route)
The most direct access starts from a small lay-by on the Priests Leap road (grid reference V98530 61072). Space is limited to about two cars, so arrive early on busy weekends. From the lay-by, follow the farm tracks north-east towards the ridge. The path is unpaved but well-trodden, climbing steadily through heather and bog cotton. It is straightforward until you leave the tracks near the upper slopes, where navigation matters.
The Kilgarvan loop (classic 14 km circuit)
For a fuller day out, the Kilgarvan approach is widely regarded as the best way to experience the mountain. Starting on the R569 near Kilgarvan, turn left towards Bantry and look for a sharp bend where a forest track leads into the Lakinkeen area. After roughly a kilometre the formal path disappears and a drainage channel guides you onto the ridge.
The loop climbs to spot height 637 m, where a short detour left reveals the Sheen Valley. Continuing along the ridge, you pass the Caoinkeen cliffs before reaching the summit cairn. From here you can extend to Knockboy (706 m), the highest point in the range, before descending past Coumyfaun Lake and back to the road. Total ascent is around 750 m over dry heather, boggy clay and rock. Allow six hours for the full circuit.
What to expect
- Summit views: The reward is the panorama. Look west to the Atlantic, north towards the Iveragh and Beara peninsulas, and south over Cork’s coastal lowlands. The corrie lake below is at its best in the low light of late afternoon.
- Wildlife & flora: The upland heath supports meadow pipits, skylarks and the occasional buzzard. Irish hares and red foxes work the lower slopes, and feral goats turn up now and then. Spring and early summer bring purple heather and white bog cotton.
- Photography: The open plateau and the drop-offs give strong conditions for landscape shots, with golden-hour light raking across the sandstone ridges and the corrie lake.
Practical information
Caoinkeen is a walk-in with no visitor centre, fee or opening hours. Access is free, but the remote setting means you need to be fully self-sufficient.
Navigation & maps: The summit sits at grid reference W01039 64554 on OSI 1:50,000 sheet 85. The lower sections are well-trodden, but the upper ridge has no continuous waymarks. A handheld GPS or a phone with offline topographic maps, plus a paper map, are essential in poor visibility.
Parking: The Priests Leap lay-by is the most convenient, though it only fits two cars. For the Kilgarvan loop, use designated roadside parking on the R569. Park well off the road and never block farm gates or access tracks.
Seasonal conditions: The mountain is walkable year-round, but winter brings snow, ice and short days. Spring through early autumn gives the most reliable conditions and the longest daylight. Summer afternoons can throw sudden Atlantic showers, so carry waterproofs whatever the forecast.
Safety & accessibility: Hill-walking carries real risk here. The terrain is uneven and steep, with exposed sections near the cliffs, and it is not suitable for wheelchairs or those with limited mobility. Check the Met Éireann forecast, carry enough food and water, and tell someone your route and return time. There are no toilets, bins or refreshments, so pack out all waste.
Getting there: The area is not served by public transport. Most walkers drive from Bantry (about 15 km) or Killarney, using the R569 or the Priests Leap road to reach the trailheads. Ballylickey and Bantry both have cafés for afterwards.
Start early to beat the afternoon Atlantic weather, and allow extra time for navigation on the upper ridge.
