Cooley Peninsula & Táin Trail

The Cooley Peninsula is Ireland's setting for the Táin Bó Cúailnge - the greatest epic of Celtic mythology. This dramatic peninsula where Cú Chulainn defended Ulster offers mountains, mythology, and Mourne views.

Why This Route?

Cooley combines legend and landscape:

• Táin mythology - Ireland's Iliad set here
• Mountain driving - Dramatic Cooley Mountains
• Mourne views - Across Carlingford Lough
• Medieval Carlingford - Perfectly preserved heritage town
• Border country - Northern Ireland visible across the water

Where to Stay

This 68-kilometre loop around the Cooley Peninsula starts and finishes in Dundalk, but the jewel of the route -- medieval Carlingford on the shore of Carlingford Lough -- is a far more atmospheric place to spend the night. Its compact size and strong hospitality scene make it the ideal single base for this day circuit.

Carlingford

Carlingford's narrow medieval streets, King John's Castle, and waterfront oyster restaurants put you at the heart of the peninsula's best scenery. From here you can head up to the Windy Gap for Mourne views in the morning, loop through Omeath, and return via Proleek Dolmen and Ravensdale Forest without ever being far from base. After a day of mountain roads and mythology, the town's pubs and seafood joints -- PJ O'Hare's for oysters, Ghan House for fine dining -- round off the experience.

The Táin Bó Cúailnge

Ireland's great epic tells of Queen Maeve of Connacht's cattle raid to capture the Brown Bull of Cooley. The hero Cú Chulainn single-handedly defended Ulster, fighting a series of combats at fords across the landscape.

The Route

Starting from Dundalk

Louth's largest town has good facilities. The County Museum covers local history and mythology.

Faughart

Birthplace of St Brigid and site of an early monastery. Edward Bruce (brother of Robert) is buried here after his 1318 defeat.

Ravensdale Forest

Pine forest with walking trails at the foot of the Cooleys.

Carlingford

The jewel of the route - a medieval town of remarkable preservation:

Medieval Heritage

• King John's Castle - Norman fortress on the harbour
• Taaffe's Castle - 16th-century tower house
• The Mint - Medieval merchant's house
• The Tholsel - Gateway in town walls
• Dominican Friary - Atmospheric ruins

Town Character

Narrow medieval streets, pubs, craft shops, oyster restaurants.

Táin Way

This 40km hiking trail circles the peninsula, following Cú Chulainn's legendary route. Day sections are walkable.

Slieve Foy

The Cooley Mountains' highest peak (589m). The ridge walk offers spectacular views but requires experience.

Long Woman's Grave

A megalithic tomb on the mountain slope, associated with a Spanish princess legend.

Windy Gap

A mountain pass with views in all directions - the Mournes across the lough, the drumlin belt inland.

Omeath

A quiet village on the lough shore, traditionally a day-trip destination from Northern Ireland — day-trippers came across on the Red Star passenger boat from Warrenpoint. There is no ferry from Omeath now. The service was passenger-only, never carried cars, and ceased around 2003. See our car ferry guide for the crossings that do still run.

Proleek Dolmen

Detour inland to see this remarkable portal tomb - a massive capstone balanced impossibly on small stones.

Practical Tips

1. Carlingford is small - Parking can be difficult on weekends
2. Mountain roads - Some are narrow; drive carefully
3. Táin Way - Download maps; some sections poorly marked
4. No ferry across the lough - The Omeath–Warrenpoint boat has not run since about 2003, and the Carlingford Lough car ferry is not sailing on any date in 2026. Drive round by Newry
5. Medieval town tour - Guides available locally

The Irish driving rules and road signs guide covers speed limits, signage and the penalty points system, which is worth ten minutes before you set off.
