Just south of Dublin, the Wicklow Mountains rise into a landscape of heather-covered peaks, glacial valleys, and dark lakes that has stood in for everything from ancient Ireland to fictional kingdoms on screen. Known as the “Garden of Ireland” for its greenery, County Wicklow offers some of the country’s most accessible wild scenery, anchored by the atmospheric monastic ruins of Glendalough. The mountains form the largest continuous upland area in Ireland, and despite sitting so close to Dublin, parts of the range still feel remarkably remote once you’re a mile or two off the main road.

What to See and Do
Explore the Monastic Site at Glendalough
Founded in the 6th century by St. Kevin, this monastic settlement in a glacier-carved valley includes a striking round tower, a small stone cathedral, and a scattering of Celtic crosses set between two lakes. The site remained an important pilgrimage destination for centuries after its founding.
Hike the Spinc Trail
This boardwalk-and-stone trail climbs steeply above Glendalough’s Upper Lake to a ridge offering sweeping views back down over both lakes and the surrounding valley. It’s a genuinely rewarding half-day hike for a moderate level of fitness, with the boardwalk sections protecting the fragile boggy ground beneath.
Drive the Sally Gap and Military Road
Built by the British in the early 19th century to help track down rebels hiding in the mountains, this road now offers one of Ireland’s most scenic drives, crossing open blanket bog and passing close to Lough Tay, often called the “Guinness Lake” for its dark water and pale sand shoreline.
Visit Powerscourt Estate
This grand estate combines formal Italianate and Japanese gardens with views toward the Sugar Loaf mountain, plus a waterfall nearby that’s Ireland’s tallest. It’s a more manicured counterpoint to the wilder scenery elsewhere in the mountains.
Spot Filming Locations
Wicklow’s valleys and moors have appeared in productions ranging from historical dramas to major fantasy series, and several tour operators now run dedicated routes to the specific spots used on screen. Even without the film connection, these same locations rank among the county’s most scenic viewpoints.
Top-Rated Wicklow Mountains Tours & Experiences
Best Time to Visit
Late spring through early autumn offers the most reliable hiking weather, with heather turning the hillsides purple in August. Ireland’s changeable weather means it’s worth planning for rain at any time of year, though a misty day can lend the valleys an even more atmospheric character.
How to Get There
The Wicklow Mountains sit under an hour south of Dublin by car, making them an easy day trip, though public transport to specific trailheads is limited compared to driving. Several tour operators run day trips from Dublin covering Glendalough and the Military Road for visitors without a car.
Good to Know
Trails and roads at higher elevations can be exposed and boggy, so waterproof boots make a real difference even on a dry-looking day. A single day covers Glendalough and a scenic drive, but a second day allows time for a proper hike and a stop at Powerscourt, along with a slower look at the smaller villages scattered through the valleys.
The Wicklow Mountains deliver a compact, dramatic slice of Irish wilderness close enough to Dublin for a day trip, yet wild enough to feel like a genuine escape from the city just an hour behind you.
