Mountains & Viewpoints in County Cork

Most of this list is packed into the south-west corner of the county, where long peninsulas run out into the Atlantic. Mizen Head is the best known: a signal station on an offshore crag, reached by an arched bridge and 99 steps, on a private site that locks when the visitor centre closes. Brow Head, above Mallavoge, is the actual southernmost point of the mainland by about nine metres, and has no car park, no railings and no café.

North of the Mizen, Sheep’s Head holds Ahakista on Kitchen Cove and Kilcrohane under Seefin, with the Goat’s Path climbing over the spine between them and Sheep’s Head Way trailheads at both. Beara, further north again, is where the Caha Mountains meet the road at the tunnelled Caha Pass and the hairpins of the Healy Pass; Bull Rock, off the tip, can only be seen from a boat.

The rest is spread thin. Knockboy, at 706m the county’s highest point, is a bog summit walked from the single-lane Priest’s Leap road on the Kerry border. Galley Head sits south-east of Clonakilty, and Old Head is inside a golf course at Kinsale, open only a few days a year. Boat trips to the Fastnet run from Baltimore and Schull, and all of it wants a clear day.

Where to start

  1. Mizen Head – Ireland's south-west edge Mizen Head

    The most south-westerly point of the mainland, with a signal station on an offshore crag reached by an arched bridge and 99 steps.

  2. Ahakista – harbour on Sheep's Head Ahakista

    A sheltered harbour halfway along Sheep's Head, with the Air India memorial garden, two Bronze Age stone circles and loops off the Sheep's Head Way.

  3. Brow Head – Ireland’s southernmost point Mallavoge

    The true southernmost point of mainland Ireland, unmanaged and unfenced, carrying a Napoleonic signal tower, Marconi ruins and old copper workings.

  4. Caha Mountains – the passes over Beara Glengarriff

    The range down the spine of Beara, topped by 685m Hungry Hill and met most easily on the Caha Pass and the Healy Pass.

Ahakista – harbour on Sheep's Head

Ahakista, cork

Ahakista sits halfway along the Sheep's Head peninsula around a sheltered harbour known as Kitchen Cove. Its memorial garden remembers the 329 people killed when Air India Flight 182 came down over the Atlantic in 1985, its sundial set to catch the sun at the moment of the explosion. Two Bronze Age stone circles and loops off the 90km Sheep's Head Way round out the reasons to come.

Brow Head – Ireland’s southernmost point

Mallavoge, cork

Brow Head, not Mizen Head, is the southernmost point of mainland Ireland – by about nine metres. The unmanaged West Cork headland carries an 1804 Napoleonic signal tower, the ruins of an early Marconi wireless station and 19th-century copper workings, and stood in for an alien coast in Star Wars: The Last Jedi. No car park, no railings, no café, just cliffs and the open Atlantic.

Fastnet Lighthouse – Ireland's Teardrop

Fastnet Rock, cork

Fastnet is Ireland's tallest lighthouse, a 54-metre Cornish-granite tower on a lone rock off West Cork and the last sight of Ireland for emigrant ships, hence its nickname, Ireland's Teardrop. You cannot land on it, but boat tours from Baltimore and Schull circle the rock; the direct trip is the pick if it is the lighthouse you are after.

Fastnet Rock – Ireland's Teardrop lighthouse

Fastnet Rock, cork

Fastnet Rock rises from the Atlantic as Ireland's southernmost point, crowned by a 54-metre granite lighthouse – the tallest rock lighthouse in Ireland or Britain. You can't land on it, but boat tours from Baltimore and Schull bring you close to the beacon that was the last sight of home for emigrants and the turning mark of the Fastnet Race.

Knockoura – a mast-topped Beara peak

Castletownbere, cork

Knockoura rises sharply from the Beara coastline, offering hikers a straightforward 4.8km trek to a trig point crowned by communication masts. The steady Atlantic breezes also make it a premier launch site for paragliders and hang-gliders seeking smooth coastal updrafts.

Old Head Lighthouse – Kinsale headland

Old Head, cork

A black-and-white banded tower, built in 1853, marks the headland nearest to where the Lusitania went down, about eleven miles offshore. The catch: it sits inside a private golf course and opens to the public only a few days a year, when a shuttle runs out from the Signal Tower. The rest of the time, the coastal loop from Garrylucas beach is how most people see it.

Toe Head – a signal tower and a shipwreck

Castletownshend, cork

Toe Head runs out into the Atlantic near Castletownshend, its ruined Napoleonic signal tower one of 81 built around 1804 to watch for a French invasion. A wartime Éire 28 sign still marks neutral Ireland, and off the point the ore carrier Kowloon Bridge went aground on the Stags in 1986. The cliffs are exposed and can be undercut, so keep well back and use only clearly permitted access.

Questions people ask

Which is actually the southernmost point, Mizen Head or Brow Head?
Brow Head, by about nine metres. Mizen Head is the most south-westerly point of the mainland and the one with the bridge, the steps and the visitor centre. Brow Head is unmanaged, with no car park, no railings and no facilities.
Can you visit the Fastnet Rock lighthouse?
You cannot land on it. Boat tours from Baltimore and Schull circle the rock, and some Baltimore trips pair the Fastnet with a landing on Cape Clear Island. If the lighthouse itself is the point, take the direct trip rather than the island one.
Which of these can I do without a long drive?
Ahakista and Kilcrohane are villages in their own right on Sheep's Head, and four Sheep's Head Way trailheads plus the Goat's Path start from Kilcrohane. Mizen Head, Brow Head and Knockboy all need a drive out, and Bull Rock needs a boat as well.
When is the best time to go?
A clear day matters more than the season. Knockboy gives 360-degree views over Bantry Bay and the Cahas only when the cloud is off the summit, and boat trips to the Fastnet and Bull Rock depend on the sea. Whales pass Mizen Head in summer.
Are any of these access-restricted?
Yes. Mizen Head is a private site and locked when the centre is closed, so check times before driving out. Old Head Lighthouse sits inside a private golf course and opens only a few days a year. Galley Head's tower opens during Heritage Week.
