Wicklow Mountains – Overview & National Park

Overview

The Wicklow Mountains form Ireland’s largest continuous upland area, stretching across County Wicklow and spilling into Dublin, Wexford and Carlow. Covering almost 23,000 ha within the Wicklow Mountains National Park, the range is a patchwork of blanket bog, heath, ancient woodlands and open grassland. The park is free to enter, open year‑round and provides an accessible wilderness escape for city dwellers and tourists alike.

History & Background

Human activity in the uplands dates back to the Neolithic, when passage tombs were erected on summits such as Seefin and Seefingan. In the 6th century AD Saint Kevin founded the monastic settlement at Glendalough, which grew into a centre of learning and pilgrimage. The Norman invasion of 1170 saw the construction of the original Wicklow Military Road, later rebuilt between 1800‑1809 to suppress post‑1798 rebellion. During the 16th and 17th centuries the O’Byrne and O’Toole clans used the mountains as a stronghold, a period remembered locally as the terra guerre.

Victorian tourists were drawn to the dramatic scenery and Glendalough ruins, and the idea of protecting the landscape was debated for decades. Taoiseach Charles Haughey announced the park’s creation at Glendalough in 1988; an interpretative centre opened in 1990 and the park was formally established in 1991 under the stewardship of the National Parks and Wildlife Service. Subsequent land acquisitions in May 2009 and 2016 extended the boundary to include Kippure, Glenasmole Valley and Bohernabreena Reservoir, safeguarding further habitats.

The park is designated as a Special Area of Conservation and a Special Protection Area under EU law, protecting species such as red‑sika deer, peregrine falcons and merlins.

What to See & Do

Glendalough Monastic City

Nestled in a glacial valley, Glendalough is the park’s crown jewel. Visitors can explore the 6th‑century monastic ruins, round tower, St Kevin’s Church, stone cross and the tranquil Upper and Lower Lakes. The Glendalough Visitor Centre (Bolger’s Cottage on the Miners’ Road) provides interpretive displays, maps and a small shop.

Iconic Peaks & Walks

• Lugnaquilla – Ireland’s highest summit outside Kerry (925 m). The most popular ascent starts from the Glenmalure valley and takes 6‑7 hours round‑trip.
• Great Sugarloaf – A conical hill on the eastern edge, reachable via a short 1‑hour walk with views of Dublin Bay.
• Djouce Mountain – Offers a 2‑hour loop through mixed woodland and a boardwalk that protects the underlying bog.
• The Wicklow Way – Ireland’s first National Waymarked Trail (130 km) traverses the park, linking Glendalough to the southern foothills.

Way‑marked Walks from Glendalough

Long‑distance routes such as St Kevin’s Way (30 km) and Miner’s Way (19 km) also cross the park, offering multi‑day trekking options.

Scenic Drives

The Sally Gap Drive (Military Road, R115) is hailed as one of Ireland’s most beautiful routes. Starting in Roundwood, the road climbs past Lough Tay (the “Guinness Lake”), Glenmacnass Waterfall and sweeping blanket‑bog plateaux before descending into the dramatic Sally Gap. The drive showcases the park’s high passes, open ridges and striking vistas.

Wildlife & Birdwatching

The park’s varied habitats support a range of wildlife. Red‑sika deer roam the open grasslands, while the blanket bogs provide breeding grounds for ground‑nesting birds such as the meadow pipit. Raptors are a highlight for birdwatchers: peregrine falcons and merlins can often be seen soaring over the ridges, especially in spring and early summer. The lakes and wetlands attract waterfowl, including teal, mallard and the occasional goldeneye. Designated viewing points near the Upper Lake and along the Spinc trail are popular spots for quiet observation.

Cycling & Mountain Biking

For two‑wheeled adventurers, the park offers both gentle cycle routes and challenging off‑road trails. The Wicklow Way is largely walk‑only, but several low‑traffic roads such as the R115 and R756 provide scenic cycling options linking Glendalough, the Sally Gap and the village of Roundwood. Mountain bikers can head to Ballinastoe MBT, Ireland’s premier mountain‑bike trail centre located on the southern edge of the park. The network includes flowy single‑track, technical sections and family‑friendly loops, all set against the backdrop of the Wicklow uplands.

Nearby Attractions & Day Trips

The Wicklow Mountains National Park sits within a rich tapestry of attractions that make for easy day‑trip extensions:

• Avoca Valley – a lush river valley famous for its hand‑weaving mill and scenic walks along the Avoca River.
• Blessington and its Lakes – a popular spot for sailing, fishing and lakeside picnics, just a short drive north of the park.
• Avondale Forest Park and House – the historic home of Charles Stewart Parker, set in extensive woodlands with family‑friendly trails.
• Camaderry – a striking peak overlooking Glendalough, offering a moderate loop walk with rewarding summit views.
• Aghavannagh – a quiet village gateway to the western slopes and the historic Glencree valley.

These sites can be combined into themed routes, such as a “Glendalough‑Avoca” loop or a “Mountain‑Bike & Heritage” day that pairs Ballinastoe MBT with a visit to the historic town of Baltinglass.
