Hiking in Ireland: Waymarked Trails, Peaks & Coast
Ireland's walking is gentle, green, and rain-polished: waymarked long trails through Wicklow and Kerry, the Carrauntoohil ascent, and cliff coast paths. This guide covers the trails and the weather.
Hiking involves real physical risk. Route conditions, weather, and your fitness all affect safety — check local trail conditions and forecasts before you go, carry navigation, water, and layers, and never hike beyond your ability. Times and difficulty descriptions here are general guidance, not a guarantee; consider a local guide for remote or high-altitude routes.
Ireland's hiking is defined by two things: extraordinary greenness and extraordinarily changeable weather, both products of the same Atlantic rain. The mountains are modest — Carrauntoohil, the highest, is just over 1,000 metres — but the walking is genuinely rewarding: the Wicklow Way through the 'Garden of Ireland', the Kerry and Dingle Ways along the wild southwest, the Burren's limestone pavements, and cliff paths above the Atlantic. The waymarked-trail network makes multi-day walking straightforward, the pubs make the evenings memorable, and the rain — well, the rain is part of the deal. Embrace it and Ireland is wonderful. The Irish walking day has a fixed shape: walk through whatever weather arrives, dry off in the pub, and repeat — preferably with live music.
The Wicklow Way: Ireland's classic trail
The Wicklow Way — Ireland's oldest waymarked trail, running from Dublin's suburbs to Clonmel through the Wicklow Mountains — is the natural first Irish long walk. The route passes Powerscourt Waterfall, the monastic city of Glendalough (worth a rest morning), and the open moorland of the Wicklow Gap, with B&Bs and hostels serving each stage. It's well waymarked, gently graded, and achievable by any fit walker over 5-7 days. The Dublin start makes logistics trivial — you can be on the trail within an hour of landing. The Wicklow weather is the classic Irish mix: sunshine, showers, and mist in rotation, sometimes within the hour. Pack the full rain kit regardless of the forecast and you'll love it. The Glendalough monastic site deserves an unhurried half day: 1,000 years of history in a glacial valley, and the trail passes right through it.
Kerry and Dingle: the wild southwest
The Kerry Way — Ireland's longest waymarked trail, circling the Iveragh Peninsula around Killarney — and the Dingle Way around its neighbouring peninsula offer the wildest Irish walking: Atlantic cliffs, empty beaches, mountain passes, and Gaeltacht villages where Irish is still spoken. The Kerry Way's stages link Killarney's lakes with the Black Valley (famously the last place in Ireland to get electricity) and the coastal villages of the Ring of Kerry. The Dingle Way adds the drama of the Brandon massif and the Blasket Islands views. These are 8-10 day undertakings with superb B&B infrastructure and luggage transfers available. May and September are the sweet spots: long days, settled weather (relatively), fewer midges. Stage distances vary widely — a walking distance calculator helps balance the longer Kerry days.
Carrauntoohil: Ireland's highest peak
Carrauntoohil (1,038m) in the MacGillycuddy's Reeks is Ireland's highest mountain and its most serious day walk — usually climbed via the Devil's Ladder (a steep, loose gully that lives up to its name) or the more scenic Brother O'Shea's Gully route. The mountain demands respect disproportionate to its height: the weather changes in minutes, the Devil's Ladder is genuinely hazardous in wet conditions, and navigation on the summit plateau in mist is non-trivial. Go with a guide if you're unsure, start early, and carry full mountain kit — the Kerry mountain rescue team earns its keep on this hill. On a clear day, the view from the cross-topped summit across the Reeks is Ireland's finest mountain panorama. Check an elevation finder for the true profile — the Devil's Ladder is steeper than the map suggests.
The Burren and the limestone west
The Burren in County Clare offers walking unlike anywhere else in Ireland: vast limestone pavements (clints and grykes) where Arctic and Mediterranean wildflowers grow side by side, ancient dolmens and ring forts, and the green road trails linking it all. The walking is gentle but the terrain is ankle-twisting — the grykes (cracks) demand attention, especially in rain. Spring brings the famous Burren wildflower display, one of Europe's botanical wonders. Combine it with the Cliffs of Moher coastal path (best walked early to avoid crowds) for the classic Clare double. The Burren's otherworldly light and silence make it a contemplative counterpoint to Kerry's drama. The Burren perfumery and its tea rooms make the perfect mid-walk stop: wildflower teas and famous Burren chocolate in a limestone landscape.
The Wild Atlantic Way on foot
Ireland's Wild Atlantic Way — the 2,500-kilometre coastal touring route — is best experienced on foot in sections: the Sheep's Head Way in West Cork (a superb peninsula loop), the Beara Way's wild ridges, the cliff paths of Donegal's Slieve League (among Europe's highest sea cliffs), and the Causeway Coast's basalt drama in the north. These coastal walks share a formula: big Atlantic skies, empty beaches, and villages where the pub is the evening's entertainment. The waymarking is good on the established trails; the wilder headlands need map and compass. Seabirds, seals, and the occasional basking shark are the wildlife bonus. Walk them from April to October; winter brings the full Atlantic fury.
Weather: the Irish contract
Irish hiking weather is a contract you sign at the trailhead: it will rain, the forecast will be wrong in the details, and you will have magnificent moments between the showers. The practical rules: full waterproofs (jacket and trousers) on every walk, layers for the wind chill, and a bothy-style acceptance that getting damp is normal. Met Éireann's forecasts are good for the big picture; the mountain-specific detail matters less here than in the Alps because the hills are lower — but the wind on exposed ridges (Carrauntoohil, the Reeks, Donegal) is the real hazard, capable of knocking walkers over. The reward for the rain is the green: Ireland's forty shades are not a marketing slogan but a meteorological fact. For time planning in changeable conditions, a hiking time calculator with a weather margin keeps days realistic.
When to go and the pub factor
The Irish walking season runs April to October, with May-June (long days, wildflowers, nesting seabirds) and September (harvest light, quiet trails, settled spells) the finest months. July-August brings the warmest weather and the busiest trails — and the midges in the west. Winter walking is for the hardy: short days, saturated ground, and the full Atlantic weather system. The pub factor deserves its own mention: the Irish walking day traditionally ends with a pint and often live music, and the B&B hosts along the waymarked trails are famously hospitable. Book B&Bs ahead on the popular trails in summer; the good ones fill. And learn the phrase 'soft day' — the Irish euphemism for rain you'll hear constantly, delivered with a smile.
Frequently asked questions
What is the best long-distance walk in Ireland?
The Wicklow Way for the classic first trail (5-7 days, easy logistics from Dublin); the Kerry Way for the wildest scenery (8-10 days); the Dingle Way for the best combination of mountains and coast.
How difficult is Carrauntoohil?
Ireland's most serious day walk: the Devil's Ladder route is steep and hazardous in wet conditions, and the summit plateau needs navigation in mist. Go with a guide if unsure, start early, carry full kit.
When is the best time to hike in Ireland?
May and June bring long days and wildflowers; September brings harvest light and thinner crowds. July-August is warmest but busiest; winter is for the very hardy.
Do I need waterproofs in summer?
Absolutely — full waterproof jacket and trousers on every walk, year-round. Irish weather changes hourly and the rain is part of the experience, not an exception.
Can you wild camp in Ireland?
Wild camping is generally tolerated in the mountains if done discreetly and responsibly (leave no trace, away from houses and livestock), though it's not a formal right. The B&B and hostel network makes it unnecessary on the waymarked trails.
What are midges like in Ireland?
Bothersey in the west from roughly June to September, especially near water and in calm conditions. Head nets and repellent help; the east and the uplands suffer less.
