Cuilcagh Boardwalk – Stairway to Heaven

Overview

The ‘Stairway to Heaven’ is really just the last twenty minutes of this walk – a steep wooden staircase up the mountain’s shoulder – but it’s what everyone comes for, and you earn it. This is a linear out-and-back, not the loop some listings claim: the same trail there and back, about 6km (4 miles) each way by the official Marble Arch Caves signage, so roughly 12km round trip, two to five hours depending on legs and crowds. The first long stretch is a flat gravel farm track across open bog; the boardwalk and steps only take over near the end. The reward is a viewing platform on the edge of the plateau, looking out over Lower Lough Erne and the Cavan drumlins.

If you have the energy for one thing here, it’s the climb to the platform – the flat track is a means to an end, not the scenery. And know before you set out that the summit proper is off-limits: access beyond the platform is closed to protect the bog.

Geology & history

The lower ground is limestone – the “Fertile Rock” of grassland and grazing – and as you climb it gives way to blanket bog, a peat-forming ecosystem built up slowly over thousands of years. The whole point of the boardwalk is to keep walkers off that peat, which erodes fast under boots and recovers over centuries.

The Sheridan family, who farm this land, built the boardwalk in 2015–16 as a conservation project, raising the route above the bog so footfall doesn’t damage it. Cuilcagh carries a stack of protections – Special Area of Conservation, Area of Special Scientific Interest, Natura 2000 site, and Ramsar wetland of international importance – and the trail runs through working farmland the whole way.

Flora and fauna

The bog supports specialist plants adapted to acidic, waterlogged ground. In spring look for bog cotton and purple saxifrage; by summer the slopes carry heather and purple moor-grass. It’s a breeding ground for ground-nesting birds too – Eurasian curlew, red grouse and golden plover – which is part of why dogs are banned and why you’re asked to stay on the boards. Curlew head-starting programmes run here through the Breeding Waders European Innovation Partnership.

Seasonal Highlights

• Spring (March–May): Wildflowers emerge, and the air fills with the distinctive calls of curlews returning to the moor.
• Summer (June–August): Heather is in full bloom, providing colour and shelter for insects. Longer daylight hours make the summit walk comfortable.
• Autumn (September–November): The heather turns golden and russet. The plateau offers spectacular sunset views over the Lough Erne islands.
• Winter (December–February): A stark, mist-filled landscape with fewer visitors. Be aware that high winds or heavy snow can lead to temporary closures.

Practical information

Marble Arch Caves grades the trail Moderate to Difficult – the gravel track is easy going, but the final staircase is steep and not for the faint of heart. There’s no charge to walk it; the only cost is parking. The boardwalk itself is signed as open 7am–11pm daily, but the official car park runs on shorter hours (roughly 7am–7pm, with the last booking slot at 4pm), so plan your arrival around the car park, not the trail.

Parking

Pre-booking matters here – the whole booking system exists to cap numbers and protect the bog, so don’t turn up expecting to pay at the gate.

If the official car park is booked out or you’d rather not pay, Killykeegan is the fallback – you get toilets and a picnic area, at the cost of a short walk to the trailhead. There are no toilets on the trail itself; go before you start, either at Killykeegan or at the Marble Arch Caves Visitor Centre.

Before you go

• Dogs are not permitted – this is a working farm and a Special Area of Conservation.
• Groups over 20 need prior written consent from Marble Arch Caves; schools and organisers should check in at the visitor centre first.
• Not wheelchair accessible – the stairs and steep sections rule out wheels and pushchairs.
• Mobile reception is poor across the plateau. Tell someone your plans before setting off.
• Weather turns fast up here – four seasons in a day is the norm. Waterproofs and sturdy boots year-round.
• In an emergency, call 999 or 112 and ask for Mountain Rescue.

Nearby

Within about half an hour’s drive you can pair the boardwalk with the rest of the Fermanagh lakelands:

• Castle Coole – A National Trust neo-classical mansion with formal gardens and a lake.
• Belleek – Best known for its pottery; the town also has riverside walks.
• Boa Island – The Janus stone figures and early Christian ruins.
• Boho – Rugged upland scenery and the Boho caves.
• Belcoo – A quiet village on Lower Lough Erne, worth the scenic drive.

The Marble Arch Caves Visitor Centre, a minute’s drive from the trailhead, has maps, a café and guided cave tours – and the caves themselves are the obvious add-on if the legs have anything left. Check the official website for closures before you travel; the trail shuts in severe weather and for maintenance.
