Mountains & Viewpoints in County Londonderry

Six of the eight entries here sit in the Sperrins, the range that fills the south and east of the county and runs 64 km from Strabane to Lough Neagh. Sawel, at 678m, is the high point of both Londonderry and Tyrone. Meenard reaches 625m on the same border ridge, and Slieve Gallion, a 528m volcanic plug, closes the range off at its eastern end above Lough Neagh.

The walking varies more than the heights suggest. Sawel has no marked path, just a stone fence up boggy ground to the trig point, and takes two to two and a half hours in waterproof boots. Meenard is open bog and route-finding, usually taken with Mullaghaneany on an 11 km round with map and compass. Benbradagh, above Dungiven, is short and steep, with the concrete ruins of a Cold War US Navy communications base near the top. Loughermore, also near Dungiven, is a quiet 396m Marilyn. Slieve Gallion is the outlier, since a road climbs most of the way up.

The two remaining entries are wider than a single summit. Limavady sits on the River Roe under the basalt cliffs of Binevenagh, and the Causeway Coast and Glens region takes in the coastal route that runs west to Derry. Clear air matters more here than season; the Sperrins also hold Northern Ireland’s first Dark Sky Park, with the OM Observatory at Davagh Forest.

Limavady – Roe Valley market town

Limavady, londonderry

Limavady is a market town of about 11,300 people on the River Roe, laid out on a cruciform plan in 1610 and overlooked by the basalt cliffs of Binevenagh. It gave the world the tune of 'Londonderry Air', and its 18th-century distillery, closed in 1915, was revived as a whiskey brand in 2021 with a new facility due to open near Magilligan in late 2026.

Questions people ask

Which of these summits is the easiest to reach?
Slieve Gallion, on the eastern edge of the Sperrins. A road climbs most of the way up the 528m volcanic plug, so the wide views over Lough Neagh and across to the Mournes take very little effort compared with the rest of the list.
Do I need map and compass skills for the Sperrin tops?
For Sawel and Meenard, yes. Neither has a marked path. Sawel means following a stone fence up boggy ground for roughly two to two and a half hours, and Meenard is open bog and heather, usually walked with Mullaghaneany on an 11 km round.
Which hills can I walk from Dungiven?
Benbradagh and Loughermore both sit above the town. Benbradagh is a short, steep 465m pull to the Cold War communications ruins and a 360° view over the Roe Valley. Loughermore is a quieter 396m Marilyn with a trig point looking towards Binevenagh and Donegal.
Where should I go in the Sperrins for stargazing?
Davagh Forest, which holds the OM Observatory under Northern Ireland's first Dark Sky Park. The wider Sperrin range is the quietest in Ireland, so light pollution is low across the bog. Go on a clear, moonless night and dress for exposed upland cold.
What makes a good base for these viewpoints?
Limavady works for the northern end, sitting on the River Roe beneath the basalt cliffs of Binevenagh and close to Dungiven's two hills. Coleraine suits anyone combining the county with the Causeway Coast and Glens and the coastal route towards Derry.
