Ireland is not the first country people think of for mountain biking. That is their loss. Over the past decade, the trail network here has gone from a handful of unofficial forest runs to a genuine spread of purpose-built trail centres, natural singletrack, and backcountry riding that rivals anywhere in the UK. The terrain is varied, the scenery is absurd, and on the right day there is nothing better than dropping into a trail with Atlantic mist burning off the hillside above you.
We have ridden all of these. Some are world-class. Some are scrappy but brilliant. Here are 15 trails and areas across Ireland that are genuinely worth your time — grouped by region so you can plan a proper trip or just find something close for an evening spin.
Before you head out, make sure your suspension is dialled. Our shock pressure calculator will get your sag set correctly for your weight and riding style.
Dublin and Wicklow
This is where most Irish mountain bikers start, and for good reason. Wicklow is on Dublin's doorstep and the trail building has been consistently good.
For a deeper dive into the Dublin and Wicklow area, our complete guide to mountain biking in Wicklow covers every trail worth riding, including seasonal conditions and practical tips.
1. Ballinastoe, Co. Wicklow
Grades: Red, Black | Length: ~15km of trails | Best for: Intermediate to advanced riders
Ballinastoe is the trail that put Irish mountain biking on the map. Sitting above Roundwood in the Wicklow Mountains, it offers tight, rooty singletrack through pine forest with enough technical features to keep you honest. The red loop is the main draw — flowing berms, rock gardens, and some properly steep sections. The black add-on cranks up the exposure and technicality. The trailhead has decent parking and is about 50 minutes from Dublin city centre. If you only ride one trail in Ireland, this is probably it.
2. Ticknock, Co. Dublin
Grades: Green, Blue, Red | Length: ~8km of trails | Best for: Beginners and after-work spins
Ticknock is the quick fix. Sitting in the Dublin Mountains just off the M50, you can be on the trail within 30 minutes of leaving the office. The trails are short but well-maintained, and the new blue and red loops added in recent years have given it real substance. It is not destination riding, but for a Wednesday evening blast it is hard to beat. Views over Dublin Bay from the top are a bonus.
3. Glencullen Adventure Hub, Co. Dublin
Grades: Green to Red | Length: ~6km of trails | Best for: Families and newer riders, plus uplift days
Glencullen sits in the valley between Ticknock and the mountains proper. The trail centre offers a mix of flow trails and more natural terrain, and the uplift service means you can session the downhill runs without burning your legs on the climb. It is a great place to introduce someone to the sport or to spend a morning working on skills before heading to Ballinastoe in the afternoon.
4. Carrick Mountain, Co. Wicklow
Grades: Blue, Red | Length: ~10km of trails | Best for: Intermediate riders wanting variety
A newer addition to the Wicklow network, Carrick Mountain near Glenealy has quickly become a favourite. The trails make excellent use of the natural rock and gradient, and the red loop has some fast, open sections that feel very different from the tight woodland riding at Ballinastoe. Less crowded on weekends, which counts for a lot.
The South
Southern Ireland has some of the longest and most varied trail networks in the country. If you are willing to drive two or three hours from Dublin, this is where the real destination riding lives.
5. Ballyhoura, Co. Limerick
Grades: Green, Blue, Red, Black | Length: ~90km of trails | Best for: Everyone — the most complete trail centre in Ireland
Ballyhoura is the big one. Sitting on the Limerick-Cork border, it has more marked trail than anywhere else in Ireland by a significant margin. The trail network spreads across rolling hills and dense forest, with everything from gentle green loops for beginners to a black-graded descent that will test anyone. The red Castlepook loop is the standout — roughly 30km of varied singletrack with fast flowing sections, technical climbs, and enough distance to make it a proper day out. The drive from Dublin is about two and a half hours, but for a weekend trip it is absolutely worth it. Accommodation in Kilfinane is cheap and convenient.
6. Killaloe/Ballycuggaran, Co. Clare
Grades: Blue, Red | Length: ~12km of trails | Best for: Intermediate riders looking for a scenic ride
Overlooking Lough Derg near Killaloe, these trails punch above their weight. The singletrack winds through mature forest with occasional views over the lake that stop you in your tracks. The red loop has some genuinely spicy descents with off-camber roots and tight switchbacks. Combine it with a Ballyhoura trip and you have a full weekend of riding in the mid-west.
7. Killarney National Park Area, Co. Kerry
Grades: Ungraded natural trails | Length: Varies — full day rides possible | Best for: Experienced riders comfortable on unmarked terrain
Killarney is not a trail centre — it is backcountry riding at its best. The Old Kenmare Road, the trails through the national park, and the routes around Torc Mountain offer wild, remote riding through some of the most dramatic scenery in Ireland. Surfaces range from smooth forest track to rocky, boggy singletrack. Navigation skills and self-sufficiency are essential. This is the kind of riding where you will not see another person for hours and will question whether the trail you are following actually exists. Magnificent.
8. Gap of Dunloe Area, Co. Kerry
Grades: Ungraded natural trails | Length: ~20km point-to-point possible | Best for: Adventurous riders looking for an epic day out
The Gap of Dunloe is one of Ireland's most famous mountain passes, and the riding around it is extraordinary. The old road through the gap is rideable on an MTB and climbs through a glacial valley that feels prehistoric. Combined with trails in the Black Valley, you can put together a full-day route that takes in remote lakes, mountain passes, and descents back towards Killarney. Not technical in the trail centre sense, but physically demanding and scenically untouchable. Bring food, spare tubes, and a waterproof.
The West
The west coast has fewer purpose-built centres, but the ones that exist are excellent, and the natural riding is world-class.
9. Coolaney, Co. Sligo
Grades: Green, Blue, Red | Length: ~25km of trails | Best for: Intermediate riders and anyone touring the west
Coolaney is the hidden gem of Irish MTB. Tucked into the Ox Mountains south of Sligo, it has an extensive trail network that rarely gets the attention it deserves. The trails are well-built with proper drainage — which matters in Sligo — and the red loop offers sustained, flowing singletrack through ancient woodland. It is a three-hour drive from Dublin but works brilliantly as part of a Wild Atlantic Way trip. The town of Coolaney itself has a good pub-to-trail ratio.
10. Derroura, Co. Galway
Grades: Blue, Red | Length: ~14km of trails | Best for: Intermediate riders, Galway locals
Sitting on the shores of Lough Corrib near Oughterard, Derroura is a compact but rewarding trail centre. The singletrack is rocky and natural-feeling, with views over the lake and the Connemara mountains that make you forget you are on a marked trail. The red loop is short but relentless — constant up and down through granite-strewn terrain. A solid morning ride if you are in Galway.
11. Portumna Forest Park, Co. Galway
Grades: Green, Blue | Length: ~20km of trails | Best for: Beginners and families
Portumna is the gentle giant of the west. The trails are mostly flat and smooth, winding through oak woodland on the shores of Lough Derg. Not technically demanding, but beautiful and a great place to build confidence or ride with children. The forest itself is one of the finest in Ireland and the deer herd adds atmosphere.
The North
Northern Ireland has invested heavily in mountain biking, and it shows. Two of the best trail centres on the island are north of the border.
Our full guide to mountain biking near Belfast and Northern Ireland covers Rostrevor, Davagh, Castlewellan, and the rest of the northern trails in more detail, including a weekend itinerary.
12. Rostrevor, Co. Down
Grades: Red, Black | Length: ~30km of trails | Best for: Advanced riders — the best MTB in Ireland, full stop
Rostrevor is the jewel. Kilbroney Forest Park above the town has trail that would be at home in the Alps — steep, technical, beautifully built singletrack that drops through ancient woodland towards Carlingford Lough. The famous Kodak Corner offers a view across the lough that is worth the drive alone. The black-graded trails are among the most technical purpose-built trails in Ireland or the UK. The red loop is no pushover either, with sustained climbing and fast, committed descents. The town of Rostrevor is set up for mountain bikers, with bike wash, good food, and accommodation that caters to riders. If you are making one MTB trip this year, make it Rostrevor.
13. Carlingford, Co. Louth
Grades: Blue, Red | Length: ~12km of trails | Best for: Intermediate riders, weekend trip combined with Rostrevor
Just across Carlingford Lough from Rostrevor, the trails in Slieve Foy Forest offer a different character — more open, with heather-lined singletrack and views across to the Mournes. The red loop has some punchy climbs and fast descents. Carlingford is a great base for a weekend, riding here one day and getting the ferry or driving around to Rostrevor the next. The medieval town itself is worth the visit regardless.
14. Davagh Forest, Co. Tyrone
Grades: Green, Blue, Red, Black | Length: ~30km of trails | Best for: All abilities — the best all-round trail centre in the north
Davagh is purpose-built and it shows. The trail centre in the Sperrin Mountains has a full spread of grades with consistently high build quality. The green loop is one of the best beginner trails in Ireland — wide, smooth, and confidence-inspiring without being boring. The red and black loops are fast and physical, with long climbs rewarded by flowing descents through spruce forest. The Dark Sky Park status means the facilities are good, and the area is beautiful in a rugged, austere way. About two hours from Dublin, two hours from Belfast.
15. Castlewellan, Co. Down
Grades: Green, Blue, Red | Length: ~15km of trails | Best for: Intermediate riders and families
Castlewellan Forest Park sits in the shadow of the Mourne Mountains and offers a well-rounded trail network with a distinctly different feel to Rostrevor. The trails wind through mature woodland and along the lake shore, with the red loop offering enough technicality to keep intermediate riders engaged. It lacks the raw drama of Rostrevor, but it is more accessible for mixed-ability groups and the setting is gorgeous. A great warm-up venue before heading to Rostrevor or a standalone destination for riders who want trails without intimidation.
Planning Your Rides
A few practical notes that will save you time and frustration.
Weather: Ireland's weather is unpredictable, but trail conditions vary hugely by location. Wicklow trails drain well thanks to the granite substrate. Ballyhoura can be muddy after rain. Rostrevor handles wet weather surprisingly well due to the quality of the trail build. Check local MTB forums or Facebook groups before driving two hours to a waterlogged trail.
Access: Most trail centres are free to ride and maintained by Coillte (the state forestry body) in the Republic or Forest Service NI in the north. Respect the trails — don't ride when conditions are terrible and risk damaging the surface. These trails exist because of years of advocacy and volunteer work.
Bike setup: A trail or enduro hardtail will handle everything on this list. Full suspension makes the rougher trails more fun but is not essential. Tyre choice matters more than frame — run at least 2.3-inch tyres and drop the pressure lower than you think. Use our shock pressure calculator to get your suspension dialled before you go.
The quick-hit list: If you are Dublin-based and short on time, Ticknock and Glencullen are your weekday options. Ballinastoe is your Saturday morning. Rostrevor is your bank holiday weekend. Ballyhoura is your annual pilgrimage. Everything else fits around those anchors.
If you are planning to ride through the colder months, our winter mountain biking guide covers tyre setup, clothing, and which trails drain best in the wet. And if you fancy a change of pace, Ireland also has brilliant gravel riding across many of the same regions.
Ireland's trail network is still growing. New trails are being built, existing ones are being improved, and the community of riders maintaining and advocating for access is stronger than ever. Get out and ride them.
