Wicklow Gap

Overview

Wicklow Gap (Irish: Bearna Chill Mhantáin) sits at the heart of the Wicklow Mountains, perched between the peaks of Tonelagee to the north‑east and Turlough Hill / Camaderry to the south. It is one of the two paved mountain passes that cut across the range – the other being Sally Gap – and is traversed by the R756, a winding, asphalt‑surfaced road that offers drivers a dramatic ascent through open moorland, rocky outcrops and pine‑clad valleys.

At an elevation of roughly 470 m, the Gap provides one of the most rewarding viewpoints in the east of Ireland. On a clear day the eye can sweep from the rolling sea‑lit horizon of the Irish Sea to the distant peaks of Snowdonia in Wales, a sight that has made the spot a favourite stop for photographers and landscape lovers.

The Wicklow Gap Road

The 26 km stretch of road from Hollywood to Laragh is known locally as the Wicklow Gap Road. It is one of only two east‑to‑west crossings of the Wicklow Mountains, the other being the Sally Gap route. The road follows the historic Great Military Road built after the 1798 Rebellion and threads past the Kings River, the glacially‑shaped Glendasan valley and the Upper Lake at Glendalough. The landscape is dominated by yellow gorse and purple heather, with very few trees, giving the drive an almost other‑worldly feel.

History & Background

The pass has long served as a natural corridor between the western lowlands around Dunlavin and the monastic settlement of Glendalough in the east. Its strategic importance was recognised in the early 19th century when the British Army constructed the Great Military Road, a network of routes designed to suppress the 1798 Rebellion. The road that now forms the R756 follows much of that historic alignment, and the remnants of the military road can still be traced in the surrounding landscape.

In the modern era the Gap has become synonymous with outdoor recreation. The short stretch of road that leads from the pass to Turlough Hill gives access to a hydro‑electric plant that harnesses the mountain’s wind and water resources. Moreover, the Gap lies directly on Saint Kevin’s Way, a long‑distance, way‑marked walking trail that follows the ancient pilgrim route from Hollywood to Glendalough. Hikers can therefore combine a summit view with a step back into early Christian history.

Mining Heritage

Lead mining shaped the Wicklow Gap area for more than 150 years, beginning in the late 18th century and continuing until the final mine closed in 1965. Entire mining villages grew along the slopes, complete with a school for the children of workers. To support the shafts, an estimated one million trees were planted in the Glendalough valley, many of which still line the forested tracks today.

Although the mines have long ceased operation, the landscape still bears their mark: piles of stone, old adits and the remains of the Miners’ Village are visible from the road. Visitors with an eye for history can spot the Piper Stone Circles and the ruins of a monastic settlement that sit alongside the mining remains, offering a tangible link between the area’s industrial past and its earlier spiritual heritage.

What to See & Do

Driving & Cycling

The R756 is celebrated among cyclists for its steady gradient and spectacular scenery. It is classified as a Category 3 climb by the Tour de France, meaning it offers a challenging yet accessible ascent for both road‑bike enthusiasts and casual riders. The road’s hairpin bends and open vistas make it a popular route for weekend bike trips, and the summit viewpoint provides a natural photo‑stop.

Cycling statistics (Glendalough side) – Length: 6.8 km, Total ascent: 337 m, Average gradient: 4.9 %, Steepest section: 10.7 % (≈100 m). The climb is listed as a 3rd‑category climb on the Climbfinder platform and is often tackled by cyclists heading towards the village of Laragh, where a small cycle‑café provides refreshments.

Walking the Saint Kevin’s Way

For walkers, the Gap marks a key waypoint on Saint Kevin’s Way. From the pass you can set off on foot to either side:

• North‑east to Tonelagee – a moderate climb that rewards hikers with panoramic views of the surrounding peaks and the heart‑shaped Lough Ouler (Lake of the Eagle).
• South‑west to Turlough Hill – a gentler walk that passes the hydro‑electric plant and offers opportunities to explore the engineering works.

Both routes are well‑marked and can be combined into a longer day‑hike that loops back through the valley of Glendalough.

The Miners’ Road Walk

A marked Miners’ Road Walk runs alongside the old mining sites, linking the ruins of the Miners’ Village with the Piper Stone Circles and the monastic settlement. The trail is relatively flat and suitable for families; interpretive panels explain the 19th‑century lead‑mining operations and the planting of one million support trees.

Scenic Viewing

The main attraction at the summit is the viewpoint platform that juts out over the pass. From here you can see:

• The Irish Sea stretching to the east.
• The mountains of Snowdonia across the water on exceptionally clear days.
• The glacial corries and U‑shaped valleys that define the Wicklow landscape.

The viewpoint is free to use and offers a short interpretive panel that explains the geology, the Great Military Road and the mining heritage of the area.

Practical Information

Getting There

• By Car – The R756 can be accessed from the N81 at Dunlavin (west) or from the R755 at Glendalough (east). The road is fully paved and suitable for standard vehicles; however, the narrow sections near the summit require careful navigation.
• By Bicycle – The same R756 route is the preferred ascent for cyclists. Bike parking is available at the small lay‑by near the viewpoint, and a cycle‑café just before Laragh offers drinks and snacks.
• By Foot – Saint Kevin’s Way passes directly through the Gap. The nearest trailheads are the Turlough Hill car park (south) and the Tonelagee trailhead (north‑east).
• Public Transport – No direct bus serves the Gap. The closest public‑transport hub is Glendalough, reachable by Local Link routes 183 (Arklow‑Glendalough) and 895 (Sallins‑Glendalough) or by the private St Kevin’s bus (route 181) from Dublin. From Glendalough, a short drive or taxi ride brings you to the R756.

Parking

There are several modest parking areas on the Gap itself, primarily intended for walkers and cyclists. These are free but limited in number, so early arrival in the high season is advisable. Larger car parks are available at the Upper Lake, Laragh and the Visitor Centre in Glendalough, all of which provide shuttle access to surrounding trails.

Facilities

The Gap itself has minimal facilities – a viewpoint board, a small information sign and a bike‑stand. Restrooms, cafés and visitor services are located in Glendalough and the nearby villages of Laragh and Roundwood. For emergency assistance, the National Parks duty ranger can be reached on 087 980 3899 during office hours (Monday‑Friday, 09:30‑16:30 in winter, 10:00‑17:30 in summer).

Dog Friendly

Dogs are welcome on the R756 and on Saint Kevin’s Way, but they must be kept on a lead at all times to protect wildlife and other visitors, in line with National Parks guidelines.

Admission & Fees

Wicklow Gap lies within Wicklow Mountains National Park, which is open year‑round and free of charge. Parking fees may apply at the larger car parks mentioned above, but there is no entry fee for the pass itself.

Seasonal Considerations

The pass is accessible throughout the year. Winter snow can make the road icy, so drivers should check local conditions before setting off. Fog and mist are common in spring and early summer, adding a dramatic atmosphere but reducing visibility on the winding sections. The National Parks service occasionally issues temporary closures for safety or maintenance; any such notices are posted on the park’s website and at the information office in Glendalough.

Nearby Attractions

While you are in the area, consider a short detour to the Upper Lake and the Glendalough Visitor Centre, both offering additional walking routes and a chance to explore the famous monastic ruins. The Lough Ouler near Tonelagee provides a picturesque spot for a picnic, and the Kings River valley can be admired from several pull‑outs along the R756. The village of Aghavannagh lies a few kilometres north of the Gap and makes a pleasant stop for a tea or a quick walk.

Wicklow Gap offers a rare combination of high‑altitude road travel, challenging cycling, and tranquil walking routes, all framed by some of the most striking scenery in the Irish countryside. Whether you are chasing a summit view, a historic trail, or a memorable bike climb, the Gap is a natural highlight on any Wicklow itinerary.
