Overview
The Sperrin Mountains form one of Ireland’s largest upland areas, extending roughly 64 km from Strabane in the west to the shores of Lough Neagh in the east. The range straddles County Tyrone and County Londonderry and is protected as an Area of Outstanding Natural Beauty. Its landscape is a patchwork of rounded summits, blanket bog, heather‑clad moorland and glaciated valleys such as Barnes Gap, Gortin Glen and the Glenelly Valley. The highest peak, Sawel Mountain, rises to 678 m (2 224 ft) and offers panoramic views that can include the Foyle Estuary, Lough Neagh and, on a clear day, the Mourne Mountains.
Geologically the Sperrins are dominated by Precambrian metamorphic rocks, with younger Ordovician igneous intrusions on the southern flank. The mountains are sparsely populated, providing a sanctuary for a diverse range of wildlife: red fox, sika deer, pine marten, red squirrels, peregrine falcons, buzzards, sparrowhawks and, occasionally, golden eagles that wander from Donegal. The area also supports the last significant red‑grouse population in Northern Ireland and a rare alpine plant, cloudberry, on the western slopes.
Because of its remoteness and minimal artificial lighting, the Sperrins have been designated a Dark Sky area. The International Dark‑Sky Park at Davagh Forest hosts the OM Dark Sky Park and Observatory, while the Stars and Stones experience combines virtual‑reality astronomy with visits to the ancient Beaghmore Stone Circles.
History & Legends
Human activity in the Sperrins stretches back to the Bronze Age, when more than 90 stone circles and cairns were erected across the landscape. The most famous are the Beaghmore Stone Circles in the southeast, aligned to the movements of the sun, moon and stars.
In later centuries the mountains became a refuge for outlaws. The most notorious was Shane Crossagh Ó Maoláin, a raparee who evaded the law for decades before being hanged in 1720. Legend says his loot was divided at the Robber’s Table, a rocky outcrop that can still be visited today.
The Sperrins also host Ireland’s only commercially operated gold mine – the Cavanacaw Mine – a reminder of the region’s mineral wealth. Throughout the centuries the hills have been a strategic stronghold for the O’Neill clan, whose legacy is visible at the Hill of the O’Neill and the restored Ranfurly House Arts and Visitor Centre in Dungannon.
What to See & Do

Long‑distance walkers can also tackle Stage 17 of the Ulster Way (central Sperrins, 55 km) or Stage 19 (north Sperrins, 85 km), both of which weave through Glenelly Valley and offer optional detours to Sawel and Dart.
Cycling & Mountain Biking
The rolling roads of the Sperrins have earned a place in National Geographic’s Top 101 Scenic Drives. Cyclists can follow the Far and Wild guided tour or explore the Davagh Forest mountain‑bike trails, which cater to beginners (gentle loops) and experienced riders (technical descents). The Cycle Sperrins initiative provides detailed route maps for self‑guided adventures.
Star‑Gazing & Dark‑Sky Experiences
The OM Dark Sky Park and Observatory at Davagh Forest offers holographic displays, sky maps and a large telescope. For a deeper immersion, the Stars and Stones two‑hour experience blends virtual reality astronomy with a night under the glass‑roofed glamping pods at the observatory, followed by a visit to the nearby Beaghmore circles.
Visitor Centres & Cultural Sites
- An Creagán Visitor Centre – family‑friendly interpretation of the bogland and local wildlife.
- Hill of the O’Neill – panoramic viewpoint over seven Ulster counties; guided tours of Ranfurly House are available.
- Gortin Glen Forest Park – 10 km of way‑marked walking trails, a 6 km scenic drive, wildlife enclosures and a children’s playpark. Horse‑riding is permitted with a permit.
- Beaghmore Stone Circles – Bronze‑Age megalithic site with visitor information panels.
- Sperrin Sculpture Trail – a series of large‑scale artworks scattered across the hills, celebrating the region’s “giant spirit”.
Angling & Water Activities
Rivers such as the River Faughan (originating on Sawel) and the Grillagh provide excellent trout fishing. The Lough Neagh Stories centre near Magherafelt offers guided fishing trips and cultural interpretation of the lake.
Practical Information
Getting there – The nearest airports are Belfast International and Derry/Londonderry. From either airport, the A6 Glenshane Pass runs through the heart of the Sperrins, linking Strabane, Omagh and Cookstown. Bus services to Omagh and Derry connect with local taxi hire for trailheads.
Parking – Most trailheads (e.g., the Sawel loop start on Glenelly Road, Gortin Glen Forest Park, Davagh Forest) provide free car parking. Some forest‑park car parks have limited spaces in summer, so arriving early is advisable.
Visitor centres – Opening hours vary seasonally; An Creagán is open 10:00‑17:00 Mon‑Fri (closed weekends in winter). The OM Dark Sky Park operates year‑round, with evening sessions from 20:00‑22:30 during the summer months.
Admission – Access to the mountains, forest parks and most walking routes is free. The Stars and Stones experience and guided tours at Ranfurly House have separate ticket prices, which can be booked via the Discover Northern Ireland website.
Safety – The terrain includes peat‑bog sections and exposed ridges; sturdy walking boots are recommended. Wire fences guide the Sawel & Dart loop, making navigation easier in poor visibility.
