The Best Mountain Biking Trails in Ireland
Trail centres from Ticknock above Dublin to Ballyhoura's 100 km network, with Rostrevor and Glencullen in between. Ride grades and facilities.
Introduction
Ireland has far more purpose-built mountain-bike trail than the size of the place would suggest. Ballyhoura alone runs to nearly 100 km of single-track, Slieve Bloom to around 80, and Ticknock sits on the slopes of the Dublin Mountains, close enough to the city for an evening lap.
The catch is rain. Rostrevor’s rocky sections turn treacherous after a wet week, and Coolaney’s hard-pack is about the only surface in the country that genuinely holds up in the wet. Plan around the forecast rather than the calendar, and treat the Black lines as conditional on dry ground.
1. Ticknock: Dublin Mountains
Location: South-west Dublin, on the slopes of the Dublin Mountains.
Trail network: ~12 km of marked loops (Green, Blue and Red grades).
Best for: Beginners to intermediate riders looking for a quick escape from the city.
Why ride Ticknock?
- Proximity: Only a 30-minute drive from Dublin city centre, with free parking at the Ticknock car park.
- Variety: Flowy forest tracks for speed, plus natural, rocky sections that test bike handling.
- Facilities: The Trails Café offers coffee, snacks and bike-repair kits; the nearby Blue Light Pub provides hearty Irish fare and a view over Dublin.
Practical tips
- Sunrise rides give spectacular sea-level views and avoid the summer crowds.
- Bring a light waterproof jacket, the Dublin Mountains can switch from dry to misty in minutes.
- Bike rentals are available from Biking.ie if you’re travelling light.
2. The Gap: Glencullen Adventure Park
Location: Glencullen, Dublin Mountains (just north of Ticknock).
Trail network: ~8 km of purpose-built single-track, with lift-service to the top.
Difficulty: Blue to Black (technical jumps, drops and steep climbs).
Why ride The Gap?
- Uplift service: A shuttle van lifts riders and bikes to the summit, saving leg power for the descent.
- Progression: Blue loops for warm-up, Red for flow, and Black for full-on enduro thrills.
- Après-ride: Johnnie Fox’s Pub, billed as Ireland’s highest pub, serves live music and hearty meals.
Practical tips

10. Extras: Smaller Centres Worth a Detour

Fewer visitors, shorter networks. Good for a day when you would rather not queue for a berm.
Planning Your Irish MTB Adventure
- Check the weather: Irish weather can change fast. Use Met Éireann’s 48-hour forecast and pack layered clothing.
- Bike prep: A reliable full-suspension bike is recommended for technical trails; otherwise a hard-tail with 2.5-3 in travel works well on most Irish tracks.
- Safety gear: Full-face helmets for Black/Red trails, gloves, eye protection and a basic first-aid kit.
- Navigation: Most trail centres provide downloadable GPX files; Trailforks and Komoot have up-to-date maps.
- Accommodation: Book early for popular spots like Ballyhoura and Rostrevor, especially during school holidays.
- Transport: Consider renting a van with a bike rack for multi-trail itineraries; many centres have lift-services to reduce climbing.
Conclusion
The spread here is wider than the size of the country suggests. Ticknock is a long lunch break from Dublin. Ballyhoura is a weekend, and you will not ride all of it. Rostrevor will hurt you if you turn up on the wrong bike after a wet week.
If this is a first trip, start at Portumna or Coolaney. Both are forgiving, both stay rideable in poor weather, and neither will put you off the sport. Save the downhill line at Rostrevor and the Black routes at The Gap for dry ground and a full-face helmet.
