Overview
The Sligo‑Leitrim Mountains, also known as the Dartry Mountains, form a dramatic limestone backbone across north‑west Ireland. Stretching from the iconic table‑mountain Benbulben in County Sligo, through the myth‑laden Knocknarea, up to the highest summit Truskmore (647 m) on the Sligo‑Leitrim border, the range drops into the rugged Ox Mountains to the south. Designated a Special Protection Area and Special Area of Conservation, the uplands host a mosaic of grassland, blanket bog and cliff habitats that support red‑billed choughs, peregrine falcons, red deer and a wealth of wildflowers.
History & Background
The mountains are ancient; Benbulben’s limestone was sculpted over millions of years by wind, rain and sea. Archaeological sites dot the landscape – the massive cairn on Knocknarea, burial chambers over 5 000 years old, the Neolithic Carrowmore cemetery nearby, and the limestone caves of Keshcorran linked to the Morrigan goddess. Legend holds that the cairn on Knocknarea is the tomb of Queen Maeve of Connacht. The poet W.B. Yeats found endless inspiration here, his grave lying in Drumcliff beneath Benbulben’s shadow and verses such as “Under Ben Bulben” immortalising the scenery. The name Truskmore derives from the Irish Trosc Mór – “rough, large ground” – reflecting its historic role as clan territory and later as a site for a telecommunications mast.

Mountain Biking
The Ox Mountains and the foothills around Coolaney host a network of marked single‑track routes popular with local and visiting riders. The hero image shows one of these trails winding through heather‑covered slopes, offering panoramic views of Lough Gill and the Atlantic coast. Trail difficulty ranges from easy family loops to more technical sections with rock gardens and steep descents. Riders should check the latest trail conditions at the local mountain‑bike information point in Coolaney before setting off.
Wildlife & Birdwatching
The limestone cliffs and blanket‑bog habitats support a diverse bird community. In spring and early summer, red‑billed choughs perform aerial displays over the cliffs, while peregrine falcons nest on the sheer faces of Benbulben. Autumn brings migrating waders and the occasional barnacle goose. Red deer, Irish hares and badgers are regular sightings in the upland valleys, and the wildflower carpet – including spring‑time mountain avens and summer heather – attracts butterflies such as the silver‑spot skipper.
Seasonal Highlights
- Spring (April‑June) – Wildflowers carpet the plateaus; choughs return to breed; longer daylight for extended walks.
- Summer (July‑August) – Warm, dry days are ideal for the Benbulben Loop and Gleniff Horseshoe; sunrise over Benbulben is a photographer’s favourite.
- Autumn (September‑October) – Colour change on the lower slopes; migratory bird activity peaks; fewer crowds.
- Winter (November‑March) – Snow can blanket the higher ground, creating dramatic scenery; experienced walkers should be prepared for rapid weather changes.
Practical Information
- Getting there: The nearest major airport is Ireland West Airport Knock, about 80 km south of Sligo town. From there, the R284 and N4 provide access to the mountain road network.
- Transport: A car is the most convenient way to reach trailheads; regular bus services run between Sligo and towns such as Drumcliffe and Manorhamilton. No dedicated public‑transport links reach the higher trailheads.
- Parking: Free parking is available at the Benbulben car park (near Dún Cúra Lake), the Knocknarea trailhead off the R284, and the Truskmore access point off the R281. Spaces can fill quickly in summer, so early arrival is advised.
- Facilities: Toilets are provided at the Benbulben car park and at the visitor centre in Sligo town. The Sligo County Museum hosts a small exhibition on the geology and mythology of the mountains.
- Accessibility: The Truskmore summit road is paved and suitable for wheelchair users, though the final short stretch to the cairn involves uneven ground. Other routes are uneven and not suitable for wheelchairs.
- Safety: Weather can change rapidly on the exposed plateaus. Walkers should carry waterproof clothing, a map and compass, and inform someone of their route. Climbers must be equipped for technical rock.
- Guided tours: Day‑tour operators from Dublin and other cities often combine mountain hikes with cultural stops at Drumcliff, Glencar Valley and Strandhill.
