Overview
Blacklion had 175 people at the 2022 census, which makes it less a destination than a doorstep. It’s the last village on the N16 before the border: cross the bridge and you’re in Belcoo, County Fermanagh, and into Northern Ireland, where the road signs switch to miles and the money to sterling. What brings people here is what’s around it – the source of the River Shannon a few miles off, the megalithic landscape of the Cavan Burren on the hills above, and one of the best-known restaurants in the country on the main street.
If you can get a table, the one thing to plan a trip around is dinner at Neven Maguire’s MacNean House. If you can’t, make it the Cavan Burren Park – it’s free, and there’s nothing else quite like it in the region.
The Shannon Pot and the Cavan Way
A short walk from Blacklion brings you to the Shannon Pot, the traditional source of the Shannon – the longest river in Ireland rising from a small, dark, bubbling pool. It’s free and reached on foot, and it sits on the Cavan Way, the marked long-distance trail that links Blacklion with Dowra. Be aware that some argue the true source lies a little further north, across the border – but the Pot is where the tradition puts it, and it’s the better story.
The Cavan Way is the walk to do if you have the legs for it, crossing the limestone uplands beneath Cuilcagh. For a shorter outing, the village marks one end of it, so you can pick up a stretch and turn back.
Where to eat: MacNean House
The reason a village this small turns up in food guides is Neven Maguire, one of Ireland’s best-known chefs, who runs MacNean House & Restaurant on the main street. This is a destination restaurant rather than a casual stop, so book well ahead rather than arriving on spec; rooms are available if you want to make a night of it. For everyday needs there’s a shop and the tourist office in the Market House, but the village is small – don’t count on much else being open.
Cavan Burren Park and the caves
Cavan Burren Park, on the slopes above the village, is a limestone plateau scattered with megalithic tombs and prehistoric remains, laid out with several waymarked trails under Cuilcagh Mountain. There’s an interpretive centre that tells the geological and archaeological story, picnic areas, toilets, and parking for cars and coaches; entry is free and guided tours can be pre-booked. It’s the single most rewarding free thing to do from Blacklion.
Across the border in County Fermanagh, the Marble Arch Caves are one of the larger show-cave systems in Europe; the tour runs around 75 minutes and includes a stretch by boat on an underground river. The caves are in Northern Ireland, so tours are charged in sterling and you’ll need to book. The National Trust’s Florence Court house and gardens are also a short drive over the border. Blacklion sits at the centre of the Marble Arch Caves UNESCO Global Geopark that ties all this together.
The Cuilcagh boardwalk
The boardwalk up Cuilcagh – the wooden stairway across the blanket bog to a viewing platform near the summit – is the area’s headline walk, reached from the Fermanagh side. It’s a serious half-day on the legs and the weather on the plateau turns fast, so check conditions and don’t set off in low cloud.
History and heritage
The village stands in the townland of Tuam, the Irish for ‘tumulus’, and the name is earned: a stone cairn, a burial cist and two stone cashels lie within it, evidence of habitation long before any village. About 4.2 km south-east, over in County Fermanagh, the medieval ruins of Killesher Church sit on a hillside, on an early Christian site associated with St Lasser.
Blacklion’s older name was Largay, from the Irish Leargaidh, meaning ‘hillside’ – fitting for its position under Cuilcagh. It was renamed in honour of a coaching inn, the Black Lion, that once stood in the village.
