There’s a particular kind of Irish day that makes you want to lace up your boots (don't forget your hiking boot insoles for added comfort!) even before the kettle has finished boiling for your first morning coffee or cup of tea. The sky can’t quite decide what it’s doing (typical in Ireland!). The hedgerows are shining from a recent shower. Somewhere in the distance, there’s a soft, silvery line of sea or the dark fold of a mountain, or, if you're especially lucky, both are visible to you. And you just know that if you get out there early enough, you’ll have a whole world to yourself for at least an hour or so.
Ireland’s hiking scene is greatly varied for a small island. You can climb into high, rocky ridgelines in Kerry, wander quiet boardwalks over wild bogland, trace old pilgrim paths up to dramatic sea cliffs or head into national parks where the trails are so well-marked you can simply… relax into the walking. This is the ultimate guide to the “best of the best” hikes in Ireland, written for real-life adventuring: where to go, what it feels like, what to expect underfoot and the little details that make each hike memorable.
If you’re planning a trip, you’ll also find official trail and park resources shared throughout, so you can double-check route updates, facilities and local guidance before you go.

The Best Hikes in Ireland for Jaw-Dropping Views
The Spinc & Wicklow Way Loop, Glendalough (County Wicklow)
If you only do one hike near Dublin, make it this one. The Spinc is the kind of trail that makes you stop mid-sentence because the view keeps interrupting you. You climb through woodland, pass the soft rush of Poulanass Waterfall and then suddenly you’re high above Upper Lake, with the valley spread out like a painting beneath your feet. The route includes a long boardwalk section across the hillside and delivers those famous Glendalough panoramas that feel far more “wild” than you’d expect so close to the city. The National Parks walking trail guide lists the Spinc and Wicklow Way at 11.5km with a time estimate of 4 hours 15 minutes and a 490m climb and Discover Ireland describes it as a high mountain route with that same ascent figure, so it’s definitely one to take seriously if it’s been a while since your last proper hill walk.
For planning, start with the Wicklow Mountains National Park walking trails PDF and the Discover Ireland listing, which are both very practical for route expectations.
Diamond Hill, Connemara National Park (County Galway)
Diamond Hill is one of those hikes that gives you a huge “reward-to-effort” return. It’s well signposted, starts right at the visitor centre and as you gain height the views just keep unfolding: the Twelve Bens, Kylemore Abbey in the distance and the Atlantic glittering beyond. Connemara National Park highlights that the upper trail brings you to the summit and specifically calls out those Twelve Bens and Kylemore Abbey views, which honestly makes it sound like a brochure… until you’re up there seeing it for yourself.
If you’re choosing between an easier and a more challenging option, many guides describe two main routes (a shorter lower trail and a longer upper trail), which makes this a great pick if you’re travelling with mixed abilities.
Slieve League Pilgrim’s Path, Sliabh Liag (County Donegal)
Donegal does drama like nowhere else. The Slieve League cliffs feel enormous in a way that photographs never quite capture. The Pilgrim’s Path is the classic way up: a steady climb through a U-shaped valley that brings you onto the plateau where the cliffs take your breath away. Discover Ireland describes the Pilgrims’ Path as a 3.2km each-way access route, with mixed terrain and an aggregate ascent of 425m, which is a helpful “heads up” if you’re expecting a gentle stroll.
For very practical visitor info (including walk options and timings), the Sliabh Liag visitor information page is worth a read before you go.
Cuilcagh Boardwalk Trail (“Stairway to Heaven”), Fermanagh (Northern Ireland)
This one feels like stepping onto a floating path through the sky. The trail crosses blanket bogland on a boardwalk and then climbs up the stepped section that earned its nickname. The official boardwalk site describes the walk as 11km to the viewing platform and notes the steep wooden steps at the end, so it’s a proper day out rather than a quick photo stop.
If you’re going with a group, it’s also worth checking the Marble Arch Caves site guidance about larger organised groups on the trail.
Slieve Donard (Mourne Mountains), via Glen River (Northern Ireland)
If you want a classic mountain summit day, Slieve Donard delivers. WalkNI’s route info for “Slieve Donard (via Glen River)” gives you the essentials at a glance (distance and terrain), and it’s a great starting point for planning and safety.
The Best Hikes in Ireland for Wild, Rugged Adventure
Carrauntoohil & the MacGillycuddy’s Reeks (County Kerry)
Carrauntoohil is Ireland’s highest peak and the Reeks are magnificent, serious mountains that demand respect. If you’ve been dreaming of a “big” Irish hike, this is it, but it’s also one where preparation matters. Kerry Mountain Rescue has clear mountain safety guidance, including warnings about navigation and descent risks in poor visibility.
If you do go into the Reeks, also take a moment to read the visitor guidelines from the MacGillycuddy Reeks conservation project (for example, the no-dog policy and general conservation etiquette). These mountains are loved hard, and they need us to tread gently.
The Bangor Trail, Wild Nephin (County Mayo)
This is the hike people talk about in a slightly hushed voice, like they’re sharing a secret. The Bangor Trail runs through one of Ireland’s most remote-feeling landscapes and it’s not a casual day ramble. Recent trail write-ups describe a long, demanding route (often approached as a one- or two-day undertaking depending on pace and planning), and it’s a brilliant choice if you’re experienced and craving that “far from everything” sensation.
The Best Hikes in Ireland for Scenery Without the Stress
Torc Mountain, Killarney National Park (County Kerry)
Killarney is famous for a reason: lakes, woodland, waterfalls, and those soft Kerry mountains layered into the distance. Torc Mountain is a lovely way to get a summit experience while still feeling quite accessible compared with the wilder Reeks. Local route summaries commonly describe an ~8km option starting from the upper car park area, with mixed surfaces including woodland trails and open mountain sections, which makes it a solid “half-day highlight” if you’re staying in or near Killarney.
Glenveagh National Park Trails (County Donegal)
Glenveagh is a dream if you want gentle, beautiful walking with the option to scale up into harder hill days. The National Parks site emphasises that Glenveagh covers a huge area and includes easy trails for beginners, plus practical supports like a trail walker bus to get you to good starting points.
If you like having an official PDF you can save to your phone, the Glenveagh walking trails guide is genuinely handy for choosing routes on the day.
Mullaghmore Loop, The Burren (County Clare)
The Burren is a different kind of beauty: limestone underfoot, rare wildflowers in the right season, and that open, wide feeling like the landscape is breathing. I liken it to being on the moon, it's other-worldly and not like any other place you'll ever see. Mullaghmore is one of the best-known Burren loops and is regularly described as a moderate route that brings you up to a classic Burren viewpoint.

Ireland’s Iconic Long-Distance Hikes (For Weekends, Week-Long Trips, or “One Day I Will…”)
A long-distance trail in Ireland can be pure bliss and a great challenge to complete. You’re not just “doing a hike,” you’re stitching together villages, peninsulas, beaches, hills and quiet roads, and you start to feel the shape of a region in your bones.
The Dingle Way is a circular trail around the Dingle Peninsula, and the official site describes it as 179km, typically walked over 8–9 days by a reasonably fit adult. This is one where you definitely don't want to forget your hiking boot insoles and thick socks to make all the walking easier on your feet!
The Kerry Way is one of the most famous, and Sport Ireland describes it as a 230km circular route starting and finishing in Killarney, passing through beautiful towns like Glenbeigh, Caherciveen, Waterville, Sneem and Kenmare.
The Wicklow Way is a classic for its accessibility and variety, with its own official site describing it as part of Ireland’s network of waymarked ways and noting the mix of mountains, upland lakes, glacial valleys, streams, forests and farmland.
If you’re planning any of these, I always recommend starting with Sport Ireland Outdoors and Trails.ie (both are listed below as great resources for hikers) listings alongside the official trail sites, because they’re great for route summaries and waymarking info.
When to Hike in Ireland (And How to Actually Enjoy It)
Late spring through early autumn tends to be the easiest window for longer days and kinder ground conditions, but Ireland doesn’t really do guarantees. My best advice is to dress like a person who expects four seasons before lunch: a light waterproof, a warm layer and proper footwear even on “short” hikes (because a short Irish hike can still contain a bog). Make sure you have hiking boot insoles within your boots for added comfort and support for your feet.
If you’re heading into higher or more exposed terrain, take navigation seriously. Mountain rescue teams repeatedly stress that poor visibility and tricky descents can catch people out and Kerry Mountain Rescue’s safety notes are a good reminder that the summit is only half the job, you still have to get down safely!
