Overview
Tibradden Mountain (Irish: Sliabh Thigh Bródáin, meaning “mountain of Bródáin’s house”) rises to 470 m (1,570 ft) on the southern edge of the Dublin Mountains. The summit is crowned by a protected Bronze-Age cairn and offers uninterrupted 360° views across Dublin Bay, the city skyline, Two Rock Mountain to the east, and the Wicklow range to the south-west. The hill sits within the Coillte-managed Pine Forest, a mixed-species plantation of Scots pine, Japanese larch, Sitka spruce, oak and beech, interspersed with granite boulders and blanket-bog heath. Its proximity to the city makes it one of the most accessible high-point walks in the region.
Archaeology & Folklore
The cairn at the summit is a National Monument, protected since 1940. Members of the Royal Irish Academy first excavated the site in 1849, uncovering a stone-lined cist containing a Bronze-Age pottery vessel and cremated human remains. Those artefacts are now held by the National Museum of Ireland. Conservation work in 1956 clarified that the open circular chamber (roughly 3 m in diameter) and its narrow passage are 19th-century reconstructions rather than original Neolithic features. Inside the chamber, a stone bearing a double-spiral motif can be seen; the carving dates from the early 20th century and was inspired by ancient megalithic art.
Two dedication plaques in the Pine Forest commemorate the opening of the Dublin Mountains Way (19 June 2009) and the inauguration of the Dublin Mountains Partnership (24 October 2008).
On the southern slope stands O’Connell’s Rock, a granite outcrop inscribed “O’Connell’s Rock, 23 July 1823”. Daniel O’Connell addressed a crowd here during Garland Sunday celebrations. Adjacent carvings – a crude cross and a crowned figure – are thought to be 19th-century additions, possibly used as a “Mass Rock” during the Penal Laws. Local folklore links the cairn to Niall Dhú, with 19th-century accounts claiming flowers were once left on the stone in prayer for his soul, though modern scholars treat the association as legend.
Flora & Wildlife
The lower slopes are dominated by the planted pine forest, with remnants of the original 1910 pine planting still visible. Higher up the hill, the blanket-bog supports bilberry, heather, furze and gorse. In spring and early summer, the ground is carpeted with mosses and ferns, accompanied by a steady chorus of songbirds. Autumn brings a golden display of beech and oak leaves that contrasts sharply with the evergreen canopy.
Wildlife sightings are common, particularly:
- Mammals: sika deer, red fox, badger, red squirrels and occasional hare.
- Birds: great-spotted woodpecker, kestrel, red grouse, jay, sparrowhawk and a variety of winter visitors.
Hiking & Activities
The main ascent follows a well-marked 2.4 km linear loop (out-and-back) guided by red way-markers, taking most walkers about 2 hours. For a longer route, the 5.9 km Tibradden Mountain Trail climbs 214 m and works well for a full-day walk.
Near the car park, Zipit Forest Adventures operates high-ropes courses, a 500 m zip-trail, treetop walks and aerial circuits for ages 7+. The cabin is wheelchair-accessible, though the surrounding forest trails are not. Permanent orienteering courses of varying lengths are marked throughout the wood, making it a regular venue for clubs and families. The site also hosts the audio-poetry installation Sky Walkers, featuring a track titled Tibradden, O’Connell’s Rock that can be listened to on site. For photographers, early morning or late afternoon light provides the best contrast for capturing the cairn and the sweeping Dublin Bay panorama.
Practical Visitor Information
Getting There
From Dublin city centre, take the R116 toward Rathfarnham and Glencullen. The free car park sits on the left side of the road, roughly 6 km south of Johnnie Fox’s Pub. GPS coordinates for the car park: 53.242888, -6.294896. The facility holds 50 spaces and operates seasonally:
- April–September: 07:00–21:00
- October–March: 08:00–17:00
Visitors should keep valuables out of sight, as occasional vehicle break-ins have been reported.
Public Transport
- Local Link Saturday service (SD4): Runs Tallaght ↔ Tibradden Wood, stopping at Cruagh Wood and the Hell Fire Club.
- Dublin Bus routes 44B and 161: Stop at “Tibradden Road”, about a 10-minute walk to the car park.
- Taxi / rideshare: Typically 30 minutes from central Dublin, depending on traffic.
Facilities & Access
The site offers a free car park, compost toilets (for Zipit users), picnic tables near the cairn, and a small shop at the Zipit cabin. There are no permanent public toilets outside the Zipit area. Wheelchair access is limited to the Zipit cabin; forest trails are uneven and unsuitable for wheelchairs. Dogs are welcome on a lead due to grazing sheep and ground-nesting birds.
Connecting Walks
- Fairy Castle (Two Rock Mountain): A Bronze-Age passage tomb visible from Tibradden’s summit, reachable via a 2.9 km spur of the Dublin Mountains Way.
- Cruagh Wood Loop: A 4.8 km easy circuit starting near the Tibradden car park, ideal for extending your day.
- Dublin Mountains Way: The 42 km long-distance trail passes through Tibradden, linking Shankill and Tallaght. Hikers can continue south-east toward the Wicklow Way or head north-west toward Two Rock.
- Hell Fire Club (Montpelier Hill): Historic hunting-lodge ruins a short hike away, offering additional panoramic views.
Seasonal Highlights & Tips
- Spring (April–May): Wildflowers and birdsong peak; excellent conditions for photography.
- Summer (June–August): Longest daylight hours. Bring plenty of water, as the forest canopy can make midday walks warm.
- Autumn (September–October): Golden foliage and often crystal-clear visibility over Dublin Bay.
- Winter (November–March): The summit becomes windy and icy. Check Met Éireann warnings and be prepared for early car-park closure during severe weather.
Safety & Weather Tips
The cairn is a protected National Monument, so stay on marked paths to avoid damaging the site. No bins are provided; practice Leave No Trace principles. Mobile signal is generally reliable, though heavy cloud cover or storms can disrupt it. Carry a waterproof jacket and sturdy footwear, as boggy patches become slippery after rain. Arrive before the posted closing times, as the car park gates lock automatically and the descent in darkness is not recommended.
