Overview
Ticknock Forest sits on the northeastern foothills of the Dublin Mountains, just a half-hour drive from the city centre. Managed by Coillte, the site blends a commercial conifer plantation with newly planted native deciduous trees and a well-marked network of trails. From the main car park, a tarmac road climbs to the summit of Three Rock Mountain (444 m), while footpaths continue upward to Two Rock Mountain (536 m), where the iconic Fairy Castle cairn crowns the ridge. The forest offers clear, sweeping views of Dublin City, Dublin Bay, Bray Head and the distant Wicklow Mountains, making it one of the capital’s most accessible outdoor escapes.
History & The Landscape
The townland of Ticknock (Irish: Tigh an Chnoic, meaning “house of the hill”) has long served as a rural gateway to the uplands. While housing developments have expanded between the forest and the M50 motorway, the woodland itself has remained a protected natural space. In 2020, Coillte launched a significant reforestation programme, replacing sections of commercial conifer with native oak, ash, and birch. This shift is gradually restoring local biodiversity and giving the forest a more varied, seasonal character. The area also forms part of the Dublin Mountains Way long-distance route and serves as a traditional starting point for sections of the Wicklow Way.
Walking the Trails
Ticknock caters to all fitness levels, with routes ranging from gentle forest strolls to more demanding ridge walks.
- Fairy Castle Loop: The most popular route covers approximately 5.5 km and takes around 1.5 to 2 hours at a moderate pace. It follows the Dublin Mountains Way, skirts the Three Rock summit, and climbs to the Fairy Castle cairn before descending via an old rifle range back to the car park.
- Kilmashogue Route: For a longer challenge, the 13 km trail from Kilmashogue Forest adds roughly an extra hour to your hike. It involves a steady initial climb but rewards walkers with quieter paths and expansive ridge views.
- Accessibility: The tarmac road to Three Rock Mountain is easily walkable for families and those with lower mobility. Beyond the road, trails become uneven and rocky. The summit cairn itself is exposed, so weather conditions can change quickly.
Mountain Biking & Orienteering
Ticknock is a designated National Mountain Bike Centre, featuring a purpose-built network of approximately 15 km of singletrack and forest roads. The trails are waymarked in a clockwise direction with green arrows, guiding riders through tight twists, fast descents, and technical rocky sections. Bike rental and guided tours are available through local operators like Biking.ie, located near the trailhead.
Trail conditions can vary seasonally, and heavy weather or maintenance may temporarily close sections. Always check the Dublin Mountains Partnership website or Biking.ie for real-time updates before riding. For a more navigational challenge, two permanent orienteering courses are laid out across the forest: a short 1.1 km loop and a medium 2.6 km loop. Downloadable maps and answer sheets are available on the Coillte website, making it an engaging activity for families and keen walkers alike.
Art, Sound & Culture
Beyond its natural and sporting appeal, Ticknock has become a canvas for contemporary landscape art. The DLR Nature and Place programme has commissioned temporary installations by artists including Martin Healy, Méadhbh O’Connor, and Robert Coleman. Visitors can also experience “Ticknock: What’s Going On?”, an audio-walk podcast by Listen and Breathe. Designed to be listened to while hiking from the upper car park to Fairy Castle, the podcast blends ambient soundscapes with spoken poetry, offering a meditative way to engage with the forest’s shifting seasons and geology.
Getting There & Parking
- By Car: From Dublin city centre, follow the R113 past Marlay Park, turn left at the Taylor’s Grange junction, and take the second right to the forest entrance. The main car park operates on a one-way system and offers around 145 free spaces. It fills quickly on weekends and clear days, so arriving early is highly recommended. The approach road can be narrow and slippery after rain.
- By Public Transport: Dublin Bus routes 44 and 47 stop near Stepaside, with a short walk up Fernhill Park to the trail network. The number 145 bus drops passengers near the Blue Light Pub, reducing road walking. Alternatively, take the Luas Green Line to The Gallops and walk 2 km up Kilgobbin Road to join the Dublin Mountains Way.
- By Bike: The forest is well-connected to the city’s cycling network. Check the Dublin Mountains interactive map for bike-friendly routes leading directly to the car park.
Practical Information
- Opening hours: Car park gates open at 06:00 and close at 22:00 daily. The forest is accessible during daylight hours, but gates may close early during severe weather or maintenance.
- Facilities: There are no permanent toilets or bins on site. Visitors are asked to follow Leave No Trace principles and carry out all waste. A small shelter at the car park provides seating.
- Food & Drink: Trails Café at Ticknock sits in the main car park, serving Fixx barista coffee, loose-leaf teas, locally baked goods, and hot toasted sandwiches. Outdoor picnic benches and bike racks make it a convenient stop before or after a trail.
- Safety & Conditions: The car park may close temporarily under Met Éireann snow, ice, or Red Wind warnings. Trail conditions can vary, especially after heavy rain. Always check official sites for closures.
- Dogs: Leashed dogs are welcome on all trails. Please ensure they are under control and clean up after them.
- Navigation: Detailed walking and biking maps are available for download on the Coillte site. The HiiKER app offers offline route guidance, while Ordnance Survey Discovery Series Sheet 50 covers the area for traditional map readers.
Nearby Attractions
- Marlay Park: A short drive away, offering formal gardens, woodlands, and a playground.
- Glencullen: Home to Johnnie Fox’s Pub, Ireland’s highest public house, and the start of several rugged mountain routes.

Plan your visit for a weekday morning to secure parking and enjoy the trails before the crowds arrive. Pack sturdy footwear, a waterproof layer, and plenty of water, as the summit is fully exposed and temperatures drop noticeably above the tree line.
