Overview
The Curraun (or Corraun) Peninsula sits at the western edge of County Mayo, forming the natural land bridge between the Irish mainland and Achill Island. At its narrowest point, the headland is just 800 metres wide, yet 99% of its perimeter is washed by the Atlantic Ocean, giving it the distinct character of a rugged island. The peninsula is home to a small, tightly knit Gaeltacht community spread across the villages of Tornragee, Polranny, Belfarsad, Currane and Dogh Beg. Irish is spoken daily by a significant portion of residents, and the local accent and place names add a distinct cultural layer to the landscape.

History & Heritage
The peninsula’s past stretches back millennia. Archaeological surveys have uncovered megalithic tombs, promontory forts and stone circles, pointing to continuous settlement for over 5,000 years. The most visible medieval relic is Kildavnet Tower, a 15th-century tower house often referred to as Granuaile’s Castle. It ties the area directly to Grace O’Malley, the formidable pirate queen whose O’Malley clan dominated these waters in the 16th century.
Later centuries brought their own notable figures. The Protestant Rev. Edward Nangle founded the Achill Mission (locally known as “the Colony”) at Dugort in the 19th century, establishing schools, an orphanage and a hospital that shaped local life for decades. Further south, Captain Charles Boycott once leased land at Keem Bay before moving to Corrymore House, where he crossed paths with Michael Davitt, founder of the Irish Land League. The peninsula also produced James Lynchehaun of Polranny, whose 1894 attack on Valley House became the real-life inspiration for J. M. Synge’s groundbreaking play The Playboy of the Western World.
Walking & Cycling
The peninsula is a haven for active travellers, offering everything from gentle coastal paths to demanding mountain ascents.
The Great Western Greenway
Running along the northern edge of the peninsula, the Great Western Greenway is a 42-kilometre traffic-free route built on a former railway line. It’s completely flat, well-surfaced and ideal for families, casual walkers and cyclists. The path delivers uninterrupted views of Clew Bay and the 365 islands scattered across it, with frequent access to local villages and cafés.
Atlantic Drive & Hill Walking
For those seeking elevation, the Atlantic Drive’s Loop 1 forms a 20-kilometre circuit starting from Achill Sound. After crossing the Michael Davitt Bridge, the R319 winds through Polranny and Owenduff before hugging the cliff edge near Mulranny. The route is low-gradient and suitable for road bikes, though cyclists should allow for occasional headwinds and narrow stretches.
Beyond the roads, the valley between Polranny Hill (452 m) and Curraun Hill (524 m) offers serious hill-walking. The marked trails wind through blanket bog, mixed woodland and a chain of small lakes including Loughaun and Cullydoo. From Curraun Hill’s summit, the vista stretches across Clew Bay to Croagh Patrick, the Connemara mountains and the distant Mullet Peninsula. The full ascent typically takes four to five hours with roughly 700 metres of elevation gain, so sturdy boots and a reliable map are essential.
Cultural & Natural Highlights
- Kildavnet Tower – Standing above the Sound, this well-preserved tower house offers a tangible link to the O’Malley maritime empire. It’s open seasonally, but the exterior and surrounding grounds can be viewed year-round.
- Mulranny Village – Awarded the 2011 EDEN European Destination of Excellence for sustainable tourism, Mulranny serves as the peninsula’s main hub. It features a range of guesthouses, restaurants and the Blue-Flag-rated Mulranny Strand, a sheltered bay ideal for safe swimming.
- Fr Griffin Park – A local sports field in Currane with panoramic views toward Croagh Patrick and Achillbeg. It’s a great spot to catch a community Gaelic football or soccer match.
- Valley House – Now operating as a hostel, bar and restaurant, this historic building hosts a woodland faerie trail and occasional cultural events, keeping the legacy of James Lynchehaun’s story alive in a modern setting.
The landscape itself is a wildlife haven. Machair grasslands and coastal cliffs support breeding populations of chough, golden plover and peregrine falcon. Sea anglers frequent the rocky points for cod, ling and blue shark, while the inland lakes hold brown trout.
Practical Information
- Getting There – Drive to Achill Sound via the N59 and cross the Michael Davitt Bridge. The R319 loops around the peninsula, connecting back to the N59 at the southern end.
- Public Transport – Bus services run from Westport, Galway and Dublin to Achill Sound. From there, local taxis or bike hire can take you further onto the peninsula.
- Parking & Facilities – Free roadside parking is available at most lay-bys along the R319 and at the Greenway trailhead near Mulranny. Public toilets are located in Mulranny village and at the Greenway start point. Refreshments and accommodation are concentrated in Mulranny and the surrounding Gaeltacht villages.
- Dog-Friendly Access – Dogs are welcome on the Greenway and most walking routes. Keep them on a lead in boggy sections and around livestock, and always clear up after them.
- Safety – Weather on the west coast can shift rapidly. The upland trails are unfenced and cross wet peat, so carry a waterproof jacket, wear grippy footwear and check conditions before heading out. Tell someone your planned route, especially if tackling Curraun Hill.
Best Time to Visit
Spring brings wild thyme, daisies and lady’s-straw to the coastal grasslands, while summer offers the calmest seas for swimming at Mulranny. Autumn delivers golden light and fewer crowds, making it ideal for photography and hiking. Winter brings dramatic Atlantic swells and mist-shrouded cliffs, best suited for experienced walkers comfortable with shorter daylight hours.
Most visitors base themselves in Mulranny or Achill Sound, then spend a full day combining a Greenway walk, a coastal cycle and a climb up Curraun Hill. Pack a picnic, allow extra time for the cliff-edge lay-bys, and you’ll experience one of the Wild Atlantic Way’s most authentic, uncommercialised landscapes.
