Top trails
Routes worth lacing up your boots for.
-
1
Croagh Patrick
Ireland's most sacred mountain and one of its most rewarding hikes. The rocky quartzite ascent requires care near the summit, but the views over Clew Bay with its hundreds of islands are incomparable.
-
2
Glendalough Upper Lake Loop
A classic Wicklow walk circling the atmospheric upper lake of Glendalough, passing the 6th-century monastic ruins, ancient oak woods, and two pristine mountain lakes. One of the most beautiful valleys in Ireland.
-
3
Cliffs of Moher Coastal Walk
The full cliff walk from Doolin to Liscannor offers the most dramatic perspectives on Ireland's most famous sea cliffs. The walk takes you to remote sections away from the visitor centre crowds.
-
4
Carrauntoohil via Devil's Ladder
The ascent of Ireland's highest peak via the classic Devil's Ladder gully route. Requires good navigation and fitness; the loose scree near the summit and summit cross rewarding the hardiest hikers.
-
5
Killarney Black Valley Circuit
A hidden gem circuit through the remote Black Valley, one of Ireland's most beautiful and least visited areas. Ancient glacial valleys, mountain passes, and the remote youth hostel at the valley's heart create an unforgettable experience.
-
6
Slieve League Sea Cliffs
Europe's highest accessible sea cliffs at 601 meters dwarf the famous Cliffs of Moher. The walk along the ridge with the Atlantic crashing far below is both exhilarating and terrifying in equal measure.
-
7
Wicklow Way
Ireland's first long-distance walking route crosses the Wicklow Mountains through wild moorland, mountain passes, and wooded valleys. Day sections can be done independently, but the full route rewards those who walk it end to end.
-
8
Diamond Hill Loop, Connemara
The most accessible challenging walk in the west of Ireland, with a well-maintained path from the Connemara National Park visitor centre to the summit of Diamond Hill. Panoramic views of Kylemore Abbey and the Twelve Bens range reward the climb.
-
9
Causeway Coast Walk
The most spectacular coastal walk in Northern Ireland linking the Giant's Causeway with Carrick-a-Rede rope bridge through dramatic basalt cliff scenery. Passes sea stacks, bays, and historic ruins.

When to hike
Seasonal conditions in Ireland.
- Spring
- March to May brings longer days, lower crowds, and wildflowers on the Burren. Trails can be wet and some mountain routes muddy. Excellent for birdwatching. Pack waterproofs.
- Summer
- June to August is peak season with longest days (18+ hours in June) and best weather probability. Very busy at popular trails; start early. Midges (biting insects) can be bothersome in sheltered areas.
- Fall
- September and October offer the best combination of good weather, low crowds, and stunning autumnal colors in wooded valleys like Glendalough and Killarney. Highly recommended.
- Winter
- November to February brings short days and challenging conditions but dramatic moody landscapes. Stick to lower altitude trails. Croagh Patrick and high Kerry peaks can have ice and snow. Brilliant solitude.
Local hazards
What to watch out for on the trail.
Hazard: Rapidly changing weather — Irish mountains can shift from sunshine to low cloud with rain in minutes; carry waterproofs even on clear days
Hazard: Cliff edges — many coastal paths have unfenced drops; stay on marked paths and keep children close
Hazard: Midges — tiny biting insects active in summer in still, sheltered areas; carry insect repellent especially in Connemara and Killarney
Hazard: Boggy ground — soft bog underfoot can be surprisingly deep; proper walking boots essential on mountain trails
Hazard: Limited mobile signal in remote valleys; download offline maps and share route plans with someone not hiking
Hazard: Mountain rescue services operate throughout Ireland; emergency number is 999 or 112, request Mountain Rescue
