Six Best Hiking Trails in Ireland for 2026

The Six Best Hiking Trails in Ireland for 2026

Ask ten people who've walked in Ireland to name their favourite trail and you'll get ten different answers. That's not a failing of the question — it's the nature of the country. Ireland is compact enough to drive across in a day, but its walking routes are diverse enough to keep you occupied for a lifetime.

This hiking trails Ireland guide cuts through the noise with six trails. Based on years of walking, guiding, and organising self-guided tours across the country, I'd recommend them to almost anyone planning a first or second walking holiday in Ireland in 2026. Each one is different in character. Together they cover the full range of what hiking in Ireland offers — mountain ridgelines, river valleys, wild Atlantic coastline, and the ancient interior.

If you're deciding where to walk, this area is where I'd start.

What Makes a Great Hiking Trails Ireland Guide?

Before the list of hiking trails Ireland guide options, it's worth being clear about the criteria—because "best" means different things to different walkers.

The six trails here score well on all of the following: scenery that earns the effort, clear waymarking so you're not navigating by instinct on mountain moorland, genuine villages at the overnight stops rather than isolated hostels, and manageable daily distances that leave you with something in reserve for the evening.

They're all walkable as self-guided hiking tours with luggage transfers — which means you carry a daypack, your bags travel between accommodations, and you arrive each evening to a comfortable B&B rather than a heavy rucksack and aching shoulders.

None of them require specialist mountaineering skills. All of them will take your breath away at least once.

1. The Wicklow Way

Distance: 127 km | Duration: 7–10 days | Difficulty: Moderate

Ireland's first and most walked long-distance trail, the Wicklow Way, fully deserves its reputation. Starting at Marlay Park on Dublin's southern fringe and finishing in the quiet village of Clonegal in County Carlow, the route crosses the open granite moorland of the Wicklow Mountains before dropping south into gentle farmland and river valleys.

What makes the Wicklow Way outstanding isn't any single section — it's the sustained quality of the whole thing. The ridge walk above Glenmalure. The descent into Glendalough, one of Ireland's most significant early Christian monastic sites, with its round tower and two glacial lakes. The final open moorland stages are above Roundwood, where the views stretch east to the Irish Sea.

Best for: First-time long-distance walkers, those based in or flying into Dublin, and walkers seeking a mix of mountain and pastoral scenery.

WHI tours: 5-day, 7-day, 10-day Wicklow Way

2. The Kerry Way

Distance: 214 km | Duration: 9–12 days | Difficulty: Moderate to Challenging

Ireland's longest waymarked trail makes a full circuit of the Iveragh Peninsula — the largest of Kerry's magnificent Atlantic peninsulas and home to some of the most dramatic scenery in Western Europe. The Kerry Way passes through Killarney National Park, climbs mountain passes with views to the Skellig Islands, traces remote river valleys, and winds along a coastline that faces nothing but open ocean all the way to America.

This is the trail that changes walkers. The combination of scale, remoteness, and genuine wildness—Kerry is genuinely wild in places, and the weather reminds you of that—creates an intense experience that shorter or easier trails don't. I've walked this route more times than I can count, and it still delivers something new each time.

The village stops along the Kerry Way are excellent: Kenmare, Caherdaniel, Waterville, and Sneem—traditional Kerry communities where the hospitality is as authentic as the scenery.

Best for: experienced walkers looking for a serious multi-day challenge, anyone who wants genuine Atlantic mountain scenery, and walkers with 10 to 14 days available.

3. The Dingle Way

Distance: 162 km | Duration: 7–9 days | Difficulty: Moderate

The Dingle Peninsula is one of the most photographed places in Ireland, and the Dingle Way gives you a week of walking through that landscape rather than driving past it. The trail makes a full loop of the peninsula, starting and finishing in Dingle Town — arguably the finest small town in Ireland and an excellent base for rest days.

What makes the Dingle Way special is the combination of high ground and coastline. The trail crosses the spine of the peninsula – the Brandon Range and the Slieve Mish mountains – with sustained ridge views in both directions, then drops back to sea level along stretches of coast where the Atlantic rollers break against dark cliffs and the next landfall west is North America.

Dingle Town itself is a draw. Dingle Town boasts excellent restaurants, traditional pubs featuring live music most evenings, and a vibrant community that welcomes walkers without overwhelming them. It's the kind of place you arrive planning to spend one night and leave wishing you'd stayed three.

Best for: walkers who want a mix of serious ridge walking and coastal paths; anyone who values a lively base town; those comparing the Dingle Way with the Kerry Way.

WHI tours: Dingle Way 8-day tour

4. The Barrow Way

Distance: 114 km | Duration: 5–8 days | Difficulty: Easy to Moderate

The Barrow Way is Ireland's hidden gem among long-distance trails — not literally hidden, but consistently underrated relative to what it delivers. Following the River Barrow south from Lowtown in County Kildare to St Mullins in County Carlow, the route is flat, pastoral, deeply Irish walking at its most accessible.

The trail follows the river towpath for much of its length — old barge paths along one of Ireland's great inland waterways, wide and flat and easy underfoot. The villages along the Barrow are small and genuine: Leighlinbridge, Graiguenamanagh, and St. Mullins—communities where walkers are warmly welcomed and where an evening pint in a canalside pub is one of the more civilised experiences available on an Irish walking trail.

Don't confuse simple terrain with an uninteresting walk. The Barrow landscape is subtly beautiful — mediaeval bridge ruins, herons standing motionless in the shallows, and the river changing character through the seasons. Walkers who've done both the Kerry Way and the Barrow Way often say the Barrow is the one they think about more often.

Best for: Less experienced walkers, over-50s, anyone whose knees prefer flat ground, and those who want to experience rural Ireland away from the tourist trail.

WHI tours: Barrow Way 5-day, Full Barrow Way 8-day

5. The Causeway Coast Way

Distance: 53 km | Duration: 3–5 days | Difficulty: Moderate

Northern Ireland's Causeway Coast is one of Europe's most dramatic stretches of coastline, and the Causeway Coast Way puts you on foot along the best of it. The trail runs from Ballycastle in the east to Portstewart in the west, passing the Giant's Causeway, the ruins of Dunluce Castle, and the rope bridge at Carrick-a-Rede along the way.

The daily distances are shorter than the other trails on this list, which suits the terrain — this is clifftop and coastal walking, where you want to move slowly and look properly rather than cover ground. The Giant's Causeway alone can absorb a full morning, and the drama of the basalt columns viewed from the coastal path rather than the visitor center parking lot is something entirely different.

Northern Ireland's north coast has developed a strong walking culture recently. The accommodation, the food, and the welcome for walkers in the villages along the route are excellent. Ballycastle, Ballintoy, and Bushmills are all worth the evening.

Best for: walkers with less time (3–5 days), those who want guaranteed dramatic scenery in a shorter route, and anyone interested in the Giant's Causeway as a walking rather than a touring experience.

6. The Cooley Peninsula and Mournes

Distance: varies | Duration: 3–5 days | Difficulty: Moderate

The Cooley Peninsula and Mourne Mountains walking area covers two ranges either side of Carlingford Lough – the Cooley Hills in County Louth on the Republic side and the granite peaks of the Mournes in County Down on the Northern Ireland side. Together they offer some of the finest mountain walking in Ireland's northeast, largely unknown to international walkers.

Carlingford is the centre of this walking world — a mediaeval walled town on the lough shore, with the Cooley Hills rising immediately behind it and views across the water to the Mournes. The town has excellent restaurants, comfortable accommodation, and a genuine community character that makes it one of the most enjoyable base towns on any Irish walking trail.

The Mournes themselves—walked as daytime stages from Carlingford or Newcastle— include some genuinely wild upland country. Slieve Donard (850 m), the highest peak in Northern Ireland, is a full-day walk. The rolling granite moorland between the summits offers miles of ridge walking with views stretching to Scotland on clear days.

Best for: walkers who want to combine two countries in one trip, anyone interested in less-trodden routes, and those based in Dublin who want mountain walking within two hours of the city.

How to Choose the Right Trail

Still deciding which hiking trails Ireland guide fits you? Here's a simple guide:

All six trails are available as self-guided walking holidays with luggage transfers, handpicked accommodation, and route notes. I grade each tour honestly — the Kerry Way is a different proposition from the Barrow Way, and you should know that before you book.

Planning Your Walk in 2026

A few practical notes worth knowing before you start planning.

Best season: May, June, September, and early October offer the most reliable walking weather. July and August are fine but busier. The trails are walkable year-round — Irish walkers don't stop for rain — but shoulder season gives you better light, better prices, and considerably fewer other walkers on the path.

Fitness preparation: You don't need to be an athlete. You need to be comfortable walking 12 to 16 km on consecutive days. If you're walking regularly now, you're ready. Our how-to-prepare-for-a-hike guide covers everything from training walks to what to pack.

Weather: Ireland's weather is famously variable. Good waterproofs are essential regardless of the season. Our guide to managing weather-related risks on Irish trails is worth reading before your trip.
