Overview
The Dartry Mountains form a striking limestone plateau in the north‑west of Ireland, lying between Lough Melvin, Lough Gill and Lough MacNean. The range is a dissected karst landscape, its peaks and valleys carved by successive glaciations. With 19 recognised summits, the Dartry range boasts a mix of lofty county‑tops – the highest being Truskmore at 647 m – and distinctive, sheer cliffs such as the world‑famous Benbulbin (526 m). The mountains are a magnet for hikers, climbers, photographers and anyone drawn to the wild, open skies of the Irish midlands.
History & Background
The name Dartry derives from the ancient túath of Dartraighe, a tribal kingdom that formed part of the historic kingdom of Bréifne. The range sits just north of the Breifne Mountains, which share a similar geological heritage. Over millennia, the limestone bedrock has been sculpted by ice, creating deep glacial valleys – Glencar, Glenade and Gleniff – that cut dramatic passages through the hills. These valleys have long served as routes for cattle drovers and, more recently, as scenic drives for tourists exploring the hidden heart of the west of Ireland.

The most photographed of these is Benbulbin, a flat‑topped monolith that dominates the Sligo skyline. Its sheer north face is riddled with folklore – a fairy door is said to appear on a dark patch, promising fine weather for a few days. The mountain also features in the tragic love story of Diarmuid and Gráinne, whose hidden cave on Benbulbin is one of the highest caves in Ireland.
Walking & Climbing
For the adventurous, the Benbulbin and Cloyragh Loop (AllTrails) offers a challenging ridge walk that rewards climbers with panoramic views of the Atlantic coastline, Lough Gill and the distant Slieve League cliffs. Beginners may prefer the Benbulbin Forest Walk, a gentle loop through native woodland that provides excellent photo opportunities of the mountain’s iconic silhouette.
Guided hikes are available through local operators such as High Hopes Mountaintreks – a good option for those who want expert commentary on the geology and legends of the range.
Scenic Valleys & Lakes
The glacial valleys of Glencar, Glenade and Gleniff are dotted with tranquil lakes and streams, ideal for quiet walks or picnics. The surrounding lakes – Lough Melvin, Lough Gill and Lough MacNean – add a watery contrast to the stark limestone peaks and are popular for angling and bird‑watching.
Cultural Connections
Benbulbin inspired poet W.B. Yeats, who penned the poem Under Ben Bulben while reflecting on mortality and Irish identity. Visitors can trace Yeats’s footsteps by exploring nearby literary sites such as Lissadell House and the Yeats Building in Sligo town.
Practical Information
The Dartry Mountains are a free‑entry natural area; there are no admission fees or formal opening hours. Parking is available at several trailheads, including the Benbulbin Forest Walk car park near Sligo town and the Truskmore summit lay‑by. The official guide page for the range is hosted by The Mountain Guide: https://www.themountainguide.co.uk/ireland/dartry-mountains.
While the mountains are open year‑round, the higher summits can be exposed to wind and mist, especially on the Atlantic side. The terrain is largely un‑paved, with some steep sections on the Benbulbin ridge; appropriate footwear and a basic level of fitness are advisable for the more demanding routes.
For detailed route maps and grid references, consult the individual peak pages linked from the Mountain Guide table above. The range is easily accessed by road from Sligo (via the N4) and from the town of Manorhamilton in Leitrim. Public transport options are limited, so a private car or organised tour is the most convenient way to reach the trailheads.
Key points for visitors:
- No entry fee; free parking at most trailheads.
- Best accessed by car; nearest major towns are Sligo and Manorhamilton.
- Trail information and maps are available on the Mountain Guide website.
- The area is part of the Dartry Mountains Landscape, a designated natural heritage zone, and is supported by local tourism bodies such as Leitrim Tourism.
Whether you are chasing the dramatic silhouette of Benbulbin, summiting the county‑top Truskmore, or wandering the quiet glens that wind between the lakes, the Dartry Mountains deliver a quintessential Irish mountain experience – raw, historic and unforgettable.
