How do you visit the Wicklow Mountains from Dublin?

Most visitors take an organised day tour from Dublin — Glendalough, Powerscourt and the Wicklow passes are the typical stops. Without a car, a tour is the practical option as public transport to the interior is very limited. Driving yourself is perfectly manageable; the mountains are 40 km from Dublin city centre and the roads, while narrow in places, are straightforward.

Wicklow Mountains guide: day trips from Dublin, hikes and highlights

Ireland’s garden on Dublin’s doorstep

The Wicklow Mountains begin almost immediately south of Dublin’s suburban fringe and stretch for 60 km down the eastern seaboard, forming the largest continuous upland area in Ireland. The landscape they provide — blanket bog, granite moorland, glacial lakes and wooded river valleys — stands in near-complete contrast to the city immediately to the north. For a day trip from Dublin, the Wicklow Mountains deliver what Ireland is routinely promised to deliver: dramatic scenery, ancient monastic ruins and green emptiness, all within 40–50 km of O’Connell Street.

The area encompasses Glendalough (the most visited single site), Powerscourt Estate and its waterfall, the Sally Gap mountain pass, Lough Tay (the “Guinness Lake”), the Vale of Avoca, and the 127 km Wicklow Way walking trail. No other area within day-trip distance of Dublin offers comparable variety.

Getting to the Wicklow Mountains

By car: the most flexible option and straightforward from Dublin. Take the N11 south towards Bray, then follow the R755/R756 inland through Roundwood towards Laragh and Glendalough. Journey time to Glendalough is 40–60 minutes from the city centre depending on traffic. The Sally Gap approach (via the R115 Military Road from the N81 at Brittas or from Rathfarnham) is longer but takes you through the high moorland and is one of the great scenic drives near Dublin.

Roads in the mountain interior are often single-track with passing places — drive attentively. Parking at Glendalough is paid and fills quickly on summer weekends.

By organised tour: without a car, an organised day tour is the practical solution. Public buses reach Wicklow Town on the coast and Rathdrum in the valleys, but service into the mountain interior (Glendalough, the Sally Gap) is too infrequent and indirect for a reliable day trip. The full-day Wicklow Mountains hike and drive tour combines the outstanding mountain landscape with Glendalough in an 8.5-hour day and is consistently one of the best-rated day tours from Dublin.

For a focus on Glendalough with mountain scenery en route, the Wild Wicklow Glendalough day tour is the most popular option. A combination including Powerscourt and Lough Tay is covered by the Powerscourt, Guinness Lake and Glendalough tour.

The key highlights

Glendalough

The valley with two glacial lakes and the ruins of a 6th-century monastic city is the single most visited site in County Wicklow and one of the best-preserved early medieval monastic settlements in western Europe. The round tower, cathedral ruins, smaller oratories and surrounding woodland valley combine to produce a landscape with genuine atmosphere. Full detail in the Glendalough guide.

Even if you visit only Glendalough and drive there via the Military Road, the mountain approach gives an excellent sample of the wider Wicklow landscape. The winding road from Sally Gap down to Laragh, descending into the glacial valley past the cliffs above the Upper Lake, is one of the most scenic approaches to any Irish heritage site.

Powerscourt Estate

On the northern edge of the Wicklow Mountains, 24 km south of Dublin, Powerscourt combines a Palladian mansion (badly damaged by fire in 1974, partially restored) with formal Italianate terraced gardens, a Japanese garden, a walled kitchen garden and views south over the Sugar Loaf mountain. The formal garden composition — three terraces descending to the Triton Lake with the Sugar Loaf behind — is among the most photographed garden scenes in Ireland.

The Powerscourt Waterfall, 5 km from the main estate, is at 121 m the highest waterfall in Ireland. Full detail in the Powerscourt gardens and waterfall guide.

The Sally Gap and Military Road

The Military Road (now the R115) was built by the British military between 1800 and 1809 to give access to the mountains after the 1798 Rebellion, when the Wicklow Mountains had been used as a base by insurgents under Joseph Holt. It runs the length of the mountains from Rathfarnham in south Dublin county to Aghavannagh in the south of Wicklow — about 56 km of mountain road with almost no habitation.

The Sally Gap crossroads (488 m elevation) is the high point of the road and the most desolate stretch. The open blanket bog in all directions — dark peat, purple heather, granite outcrops and mountain streams — has a genuine wildness unusual for anywhere 40 km from a capital. Drive through it even if you stop nowhere else.

Lough Tay (“Guinness Lake”)

One of the most distinctive inland views in Leinster. Lough Tay lies in a deep glacial hollow between the Luggala and Fancy mountains, cupped in steep heather slopes with the Guinness family’s Luggala Estate on its northern shore. The pale sandy beach at the lake’s northern end and the very dark peat-stained water give it the colour of a pint of Guinness in the glass — hence the nickname. A lay-by on the road between Sally Gap and Roundwood gives the standard viewpoint.

The Powerscourt, Guinness Lake and Glendalough tour includes a stop at the Lough Tay viewpoint as part of the Wicklow circuit.

The Vale of Avoca and Avoca village

At the southeastern corner of the county, the rivers Avonmore and Avonbeg meet at Avoca in a wooded valley. Thomas Moore’s poem “The Meeting of the Waters” (1807) immortalised the spot; the meeting point is marked by a small terrace above the confluence. The village of Avoca is home to Avoca Handweavers, one of the oldest continuously operating businesses in Ireland (established 1723), which produces tweeds and woollens on site using traditional methods. The mill shop and café are worth a visit; the weaving floor is viewable from a gallery.

Combining Avoca with Glendalough (30 minutes apart by road) makes a satisfying south Wicklow circuit.

The Wicklow Way

Ireland’s first long-distance walking route runs 127 km from Marlay Park on the southern edge of Dublin city to Clonegal in County Carlow, crossing the full length of the Wicklow Mountains. Sections are accessible as day hikes from various trailheads. The stretch from Glendalough to Roundwood (approximately 12 km) is one of the more popular day-walk segments on good mountain terrain. The Spinc ridge above Glendalough is both part of the Wicklow Way and the finest viewpoint ridge in the county.

Hiking in the Wicklow Mountains

The range provides walking options from easy valley paths to serious summit routes:

Glendalough valley floor (3 km loop, 1 hour): flat, well surfaced, suitable for all abilities. Covered in the Glendalough guide.

The Spinc ridge (8 km loop, 3–4 hours): climbs above Glendalough Upper Lake to a ridge with spectacular valley views. Moderate to strenuous; good boots required.

Lugnaquilla (925 m): the highest peak in Leinster and in all of Munster and Leinster. Requires a full day, navigation skills and proper mountain equipment. Not a beginner route.

Bray Head (6 km cliff walk, 2 hours each way): accessible by DART, this coastal walk at the southern end of the mountains is described in the DART coastal day out guide.

Planning a Wicklow day

Structure from Dublin by car: leave before 09:00 to beat weekend traffic. Visit Powerscourt or Sally Gap first (morning light), then Glendalough in the afternoon. Combine with Avoca for a southeast Wicklow circuit.

Structure from Dublin by tour: most Wicklow day tours depart 08:00–09:00 from central Dublin pickup points and return by 18:00. Small group tours give more flexibility at stops.

Combination days: Wicklow and Kilkenny pair well for a full south Leinster day. The Wicklow, Glendalough and Kilkenny day trip guide covers this combination.

Eating: the mountain interior has limited food options. Laragh village at the Glendalough entrance has cafés. Rathdrum (15 minutes from Glendalough) has better options. Enniskerry near Powerscourt has the Avoca café and a village pub. Bring packed lunch and water for any hiking.

Accommodation: staying overnight in Laragh (the Glendalough Hotel), Rathdrum or Ashford gives access to early morning valley conditions before the tour buses arrive. The valley at 08:00 before crowds arrive is a fundamentally different experience. The Dublin 4-day itinerary with day trips has a Wicklow day built in.

The Wicklow Mountains are covered as one of the top day-trip options in the best day trips from Dublin guide and form a central element of the Dublin wild Atlantic 5-day itinerary.
