Overview
The Legnabrocky Trail is the walking route up Cuilcagh Mountain, and since 2015 it has had a 1.6km timber boardwalk laid across the bog and a steep staircase near the top – the stretch everyone photographs and calls the Stairway to Heaven. That boardwalk changed everything: annual visitor numbers jumped from around 3,000 to more than 60,000, which is the first thing to know before you go. Come early, come midweek, or come outside the summer, because the car park is small and the steps get busy. The payoff at 666m is a 360° view across six counties, and the highest ground in both Fermanagh and Cavan under your feet.
History & Background
The bog you walk over is a Special Area of Conservation inside the Marble Arch Caves Global Geopark, the UNESCO-listed cross-border geopark that straddles Fermanagh and Cavan. The upland blanket bog here is one of the best examples in western Europe. The 1.6km boardwalk went in during 2015 specifically to keep the growing crowds off that peat, which erodes fast underfoot.
A Bronze-Age cairn sits on the summit plateau, where gritstone gives way to sandstone and shale under centuries of accumulated peat. High ground like this has drawn people for millennia.
What to See & Do
The trail is divided into two distinct experiences: the flat, accessible boardwalk and the steep climb to the top.
The Boardwalk
The 1.6km timber walkway winds through the heart of the bog. It keeps you above the waterlogged peat, offering a stable surface to observe the delicate flora without causing damage. Keep an eye out for rare bog plants like starry saxifrage, stiff sedge, sundew, and alpine clubmoss. The boardwalk gives a gentle, stable introduction to the landscape.
The Stairway to Heaven
Beyond the boardwalk, the real test begins. A 450-step wooden staircase climbs the final kilometre to the summit plateau. Small platform rest points are spaced along the ascent, giving you time to catch your breath and take in the changing scenery. The climb is steep and demands a reasonable level of fitness, but the effort is repaid at the top.
Summit & Wildlife
The plateau hosts a viewing platform and the ancient cairn. On clear days, the panorama stretches across Tyrone, Donegal, Cavan, Leitrim, Sligo, and Roscommon. You can also spot Lough Atona, a glacial lake formed around 13,000 years ago. The bog is good for wildlife: white-fronted geese, golden plovers, skylarks, meadow pipits, and mountain hares are commonly sighted, along with plenty of butterflies in the warmer months.
Walking Options
Depending on your fitness and time, you can choose from three main routes:
- Short return (from paid car park): Approximately 11km round-trip, taking 2–3 hours. This is the most popular option for a brisk half-day hike.
- Boardwalk-return loop: Around 14.8km, taking roughly 4 hours. After a 5km gravel approach, you follow the boardwalk, climb the stairs, and retrace your steps.
- Ulster Way loop: A more demanding 20km route taking 5–7 hours. From the summit, the path descends through grassy meadows and Cove Wood, following the Finglass River back to the Marble Arch Caves car park.
Practical Information
Getting There & Parking
The trailhead is about 10 miles (16km) from Enniskillen, a 40-minute drive. Follow the signs for Marble Arch Caves; the Legnabrocky car park sits just beyond the main caves car park. One thing to plan around: the Marble Arch Caves car park is locked at 7pm, so if you park there, start the walk no later than about 2.30pm to be sure of getting back before the gate closes.
| Car park | Distance to boardwalk | Fee | Notes |
|---|---|---|---|
| Paid Cuilcagh car park | Direct start | £5–£6 cash | Paid to the steward on arrival. Fills quickly on weekends. |
| Killykeegan Nature Reserve | ~1km gravel walk | Free | Some walkers use it as a free alternative when the paid lot is full; check it’s open before relying on it. |
Facilities & Access
- Toilets: Available at the paid car park.
- Food & Drink: There are no refreshment facilities on the trail. Bring plenty of water and high-energy snacks.
- Accessibility: The 1.6km boardwalk itself is flat, but reaching it means a few kilometres of gravel track from the car park first, so it’s only realistically wheelchair- or pushchair-friendly for the determined. The 450-step staircase beyond it is steep and not accessible.
- Best Time to Visit: Late spring through early autumn offers the most stable weather and the bog flora at its best. Early mornings or late afternoons provide the best light for photography and help you avoid the midday crowds.
Nearby Walking Routes
If you want to extend your day in the area, these routes pair well with Legnabrocky:
- Cladagh Glen: A shaded woodland walk along the river, through the area’s karst geology.
- Belmore Forest: A network of trails leading to a Neolithic cairn with views over Lough Erne.
- Aghanaglack Dual Court Tomb: A short detour to an impressive Neolithic burial site near the Arney River.
Tip: Summer weekends draw large numbers of walkers. Arrive before 10am to secure a parking space at the paid car park, or head straight to the Killykeegan reserve for a quieter start. Always wear sturdy footwear with good grip, as the gravel approach and wooden steps can become slippery in wet conditions.
