Where to base your trip
Glencolmcille and Carrick: For Slieve League cliffs and Pilgrim’s Path loops
Dunfanaghy: For Muckish, Horn Head and Ards Forest Park
Gweedore: For Errigal, the Poisoned Glen and Glenveagh access
Letterkenny: Transport hub with easy links to Glenveagh and the north coast
Inishowen Peninsula: For Malin Head and coast-to-summit days
Signature hikes and day routes
Slieve League Cliffs
Choose the easier Pilgrim’s Path to the ridge or the longer One Man’s Path for airy views above 600 m sea cliffs. Weather dictates the plan. In mist or high wind pick lower trails to viewpoints.
Errigal and the Poisoned Glen
A short but steep ascent on improved paths rewards with views across the Derryveagh range and Dunlewey Lough. Pair with the valley walk below the quartzite cone for a full day.
Glenveagh National Park
Mix lakeside trails with the Bridle Path to the castle and gardens. Red deer, eagles and quiet corries give a Highland feel. Good lower option in unsettled weather.
Horn Head and Dunfanaghy
Clifftop walking with sea stacks, dunes and broad beaches. Combine the headland circuit with Ards Forest Park for woodland and shore trails.
Muckish via the Miner’s Track
A steady climb on old railway beds to a broad summit plateau. Views stretch to Tory Island and the Bluestack Mountains.
Inishowen highlights
Pick from Malin Head coastal loops, Mamore Gap and the Urris Lakes circuit for big Atlantic scenes and glaciated corries.
Grading and terrain
Comfortable: Park and coastal loops in Glenveagh, Ards Forest, Horn Head and Malin Head
Moderate: Errigal, Muckish and longer Glenveagh routes with mixed, sometimes boggy ground
Energetic: Slieve League ridge variations and full mountain days linking valleys and passes
Expect peat tracks, rocky paths, boardwalk in places and quiet lanes near villages. Waterproof boots and gaiters keep you comfortable when ground is wet.
When to go
April to October offers longer daylight, blooming machair and better local services. Winter is possible for experienced hikers who plan for short days, strong winds and limited transport.
Getting there
Airports: Donegal, Derry, Belfast and Dublin
Public transport: Buses link Letterkenny with park gateways and coastal towns. Local taxis and pre-booked transfers are useful for point-to-point days.
Driving: Narrow roads and single-track sections near trailheads. Allow extra time.
Practical tips
Navigation: Weather changes quickly. Carry a map, compass and fully charged phone. Guests on our trips receive route notes, GPX files and access to the IWHB GPS Hiking & Cycling App.
Safety: Keep well back from cliff edges. Avoid high ridges in strong wind or thick mist.
Access: Respect farmland, close gates and follow local signage.
Food and water: Stock up before remote days. Many cafés operate seasonal hours.
Wildlife and culture: Look for red deer in Glenveagh and listen for Irish language place names across the Gaeltacht.
FAQs
Is Slieve League harder than the Cliffs of Moher?
Yes. Slieve League is a mountain day with steep ground and exposure. The Cliffs of Moher is a coastal walk on defined paths.
Can beginners climb Errigal?
Fit first-timers can summit in fair weather on the main path. Choose a calmer day, start early and descend if conditions worsen.
Do I need a car for Donegal hikes?
Not strictly. You can base in Letterkenny, Dunfanaghy or Gweedore and use local buses and transfers. A car gives more flexibility for early starts.
Are trails signposted?
Many are, though mountain routes may have only intermittent markers. Carry a map or GPX and know how to use them.
What clothing should I bring?
Waterproof jacket and trousers, insulating layers, hat, gloves and comfortable hiking boots. Pack covers and a head torch are recommended.
