Glencolmcille Tower Loop

Difficulty: Moderate-hard Time: 3.5-4 hours Distance: 10km with 330m ascent

The trailhead is at Ionad Siúil Lodge/Glencolmcille Fire Station. From here, the route goes clockwise, signed by blue arrows. You’ll pass cross pillars, stone chapels and megalithic tombs. When up on Beefan, you’ll find Tobar Cholmcille (St Columba’s Well). Later, it’s well worth a detour to a Napoleonic signal tower for stunning views of the Donegal coastline, including cliffs at Slieve League, before descending along paved roads. sportireland.ie

Afters: For great food, ceol and craic, head to The Rusty Mackerel along Teelin Road, a 15-minute drive via the R263. As well as great drinks, seafood is its speciality but it does burgers and pasta too; therustymackerel.com
