Belcoo, Béal Cú, Co. Fermanagh

Béal Cú · Co. Fermanagh

Two villages, one bridge, one country depending on which side of it you are standing.

Belcoo sits at a narrow neck of water between two lakes - Lough Macnean Upper to the west, Lough Macnean Lower to the east. The Irish name says it plainly: Béal Cú, the mouth of the narrow water. The village is ten miles from Enniskillen on the Fermanagh side of a bridge that has marked the Fermanagh-Cavan county boundary for centuries. Since 1921, that county boundary has also been an international one.

The two villages - Belcoo on the northern bank, Blacklion on the southern - function as a single community divided by a political border that neither asked for. In the decades after partition, the crossing was controlled, taxed and sometimes closed entirely. During the Troubles the old railway bridge was blown up by the British Army. People who wanted to cross to their neighbours, their doctor, their shop, had to think about it first. The bridge you cross today is a later replacement. The two towns share a history, a lake, and a local outlook that the border has never quite managed to separate.

At Holywell, a kilometre or two northwest, a well dedicated to St Patrick draws pilgrims between late July and 15 August - a tradition documented as far back as 1718, when a local writer described cures for sight, limb and 'other distempers'. The pilgrimage pre-dates reliable records. Máire MacNeill's 1962 study of the Lughnasa festival connects the site to pre-Christian harvest traditions; the Church absorbed them rather than displaced them. People still come in August.

The Marble Arch Caves at Florencecourt, five kilometres away, are the reason most visitors find themselves in this end of Fermanagh. The show cave opened in May 1985 after three years of development work. Visitors travel the first section by boat, which is not a gimmick but the same route taken by the French explorer Édouard-Alfred Martel when he first mapped the passages in 1895 - by canvas boat and magnesium flares. Above the caves, Cuilcagh Mountain rises to 666 metres on the Fermanagh-Cavan border, its northern slopes feeding the rivers that disappear underground to form the cave system. The boardwalk trail to the summit opened in 2015 and drew enough people to make the car park a serious management problem. The mountain doesn't know this.

At a glance.

Three things every local will eventually mention. Read these and you've already understood more than most day-trippers do.

01 The border crossing

Walk from the UK to the Republic in thirty seconds.

The bridge over the river between Lough Macnean Upper and Lough Macnean Lower marks the county and national boundary. Blacklion is on the far side, in Co. Cavan, in the Republic. The crossing has been open, closed, bombed and rebuilt. It is open now. Cross it.

Stories & lore → 02 Marble Arch Caves

Underground rivers, a boat, and 330 million years of limestone.

Five kilometres away near Florencecourt, the show cave has been running since 1985. Visitors enter by boat on the subterranean Cladagh River. The system is 11.5 km long - the longest cave in Northern Ireland. It became part of a UNESCO Global Geopark in 2004.

Walks & outings → 03 St Patrick's Well, Holywell

A pilgrimage that has run for longer than anyone can date.

At the hamlet of Holywell, northwest of the village, a holy well is attributed to St Patrick. Pilgrims gather from late July through 15 August each year. An 18th-century visitor described the water as intensely cold and the cures as numerous. Both claims are still made.

This is the Republic of Ireland - you are paying in euro, the VAT rate is different, and there is no ambiguity about which country you are in. The restaurant has a long reputation. Book well ahead. The crossing is trivial; the food is the point.

Stories & lore.

The reason to come back. The things every local will eventually tell you about, usually after the second pint.

The railway that served two countries

Belcoo and Blacklion station

In 1878, a stationmaster's house and six workers' cottages were built at Belcoo in anticipation of the railway. The Sligo, Leitrim and Northern Counties Railway line opened on 18 March 1879 with a station named 'Belcoo and Blacklion' - the only station name in Ireland that acknowledged two villages in two different places from the start. The line ran from Enniskillen down through Leitrim to Sligo, threading through some of the poorest and most sparsely populated country in Ulster. It closed on 1 October 1957; the last trains ran through on 20 September. The station is gone. The railway bridge between the two villages was blown up by the British Army in the late 1970s, on the logic that it might be used to move arms across the border. The logic is debated. The bridge is not coming back.

The holy well at Holywell

Dabhach Phádraig

In c. 1749, traveller Isaac Butler described a well near Belcoo - called Davagh Patrick, meaning St Patrick's vat - as 'the best Cold Bath in the Kingdom', reporting that it had cured 'Numbers in nervous and paralitic Disorders'. He also recorded a 1740 incident where the water turned milky for seven weeks; a local friar attributed it to marl loosened by the thaw after a great frost. The well is at Holywell, northwest of the village, within the townlands of Cavancarragh and Rushin. The pattern, or pilgrimage gathering, runs from late July through 15 August annually. Máire MacNeill, in her 1962 study 'The Festival of Lughnasa', connected the site to a local folktale about a hound whose mouth emitted fire before St Patrick killed it - a trace, she argued, of pre-Christian rites absorbed into the feast of Lughnasa. The water is still cold.

Partition, 1921

The border and its geometry

With the partition of Ireland in 1921, Belcoo became a border village overnight. It was overwhelmingly Catholic - as the 2011 census still showed, almost ninety per cent - and the Irish Boundary Commission of 1925 listed it among the villages that would have been transferred to the Irish Free State had its recommendations been enacted. They were not. For the next seven decades the crossing was subject to customs checks, military observation, and periodic closure. During the War of Independence, fifty IRA volunteers crossed from Cavan in March 1922 and seized the RIC barracks in Belcoo after a three-hour battle. After the Good Friday Agreement of 1998 the checkpoints came down and the road through became a road again. The European Union's open-border policy made crossing it the same unremarkable act it was before 1921. This is not taken entirely for granted here.

Canvas boat, magnesium flares

Marble Arch, 1895

French speleologist Édouard-Alfred Martel and Dublin naturalist Lyster Jameson first explored the Marble Arch cave system in 1895, travelling by canvas boat on the underground Cladagh River with candles and magnesium flares. They mapped 300 metres of passage and noted the junction where three rivers meet. Martel immediately saw the potential for a show cave. It took ninety years. Development began in 1982 and the cave opened to the public on 29 May 1985. The route through the show cave still begins the same way Martel went in - by boat. In 2001, the caves and Cuilcagh Mountain Park became a European Geopark, the first in the UK to be recognised by the European Geoparks Network. In 2004, under an agreement between the EGN and UNESCO, the park joined the Global Network of National Geoparks. In 2008 the geopark boundary was extended across the border into County Cavan, making it the world's first transnational cross-border geopark.

Things to do outside.

Wear waterproofs. Bring a sandwich. Tell someone where you're going if it's the mountain.

Marble Arch Caves Show Cave Tour From Belcoo, drive approximately 5 km northeast towards Florencecourt. The show cave is open March to September. Tours are guided and depart regularly. The first section is by boat on the underground Cladagh River; the remainder is on foot through lit passages. Booking ahead is sensible in summer - annual capacity is capped and tours fill up. The visitor centre has a café.

Cuilcagh Boardwalk Trail (Stairway to Heaven) The trailhead at Legnabrocky Car Park is about 8 km from Belcoo, adjacent to the Marble Arch Caves. The first 5 km are on a wide gravel track across open bog. The final kilometre climbs 450 wooden steps to a viewing gallery near the 666-metre summit of Cuilcagh - the highest point in both Fermanagh and Cavan. The views on a clear day extend over the lake country in every direction. The trail opened in 2015 specifically to protect the bog from erosion caused by walkers cutting their own lines. Use the boardwalk. The bog does not recover quickly.

Lough Macnean Lakeshore The shores of both Upper and Lower Lough Macnean are accessible by road and track from Belcoo. Upper Lough Macnean is a coarse fishing lake and its shores are quiet outside the summer months. The point where the three counties of Fermanagh, Cavan and Leitrim converge is in the centre of Upper Lough Macnean - which is to say it is underwater and not marked, but you can stand at the shore and think about it.

When to go.

There is no bad time. There are different times.

Spring

Mar-May

The Marble Arch Caves open in March and are quieter than summer. The lakes are full. The pilgrimage season has not started. A good time to have the place to yourself.

◉ Go

Summer

Jun-Aug

The holy well pilgrimage runs late July through 15 August. The caves are at their busiest. The Cuilcagh trail car park fills early at weekends. Book the caves in advance and arrive early for the walk.

◐ Mind yourself

Autumn

Sep-Oct

The caves stay open until late September. The boardwalk trail is at its best - the bog colours change and the summer crowds are gone. The lakes are excellent for fishing.

◉ Go

Winter

Nov-Feb

The show cave closes for the season. Cuilcagh is walkable in good conditions but the boardwalk can be icy and the mountain is genuinely exposed. Belcoo has few amenities open year-round - check before you travel.

◐ Mind yourself

What to skip.

Honestly? Don't bother.

If a local was sitting beside you, this is the bit where they'd lean in.

Driving through without stopping

The A4/N16 runs straight through Belcoo-Blacklion and it is easy to treat the crossing as a navigational milestone on the way to Sligo or Enniskillen. The village repays twenty minutes on foot. Cross the bridge. Look at the lakes. Read the history into the geography. Then drive on if you must.

The caves in peak summer without booking

Marble Arch has a hard annual visitor cap. Tours do fill. The car park for the caves and the Cuilcagh trailhead fills early on sunny summer weekends. Both issues have the same solution: arrive early or book ahead.

Cuilcagh in cloud without experience

The boardwalk is well-maintained but the summit is at 666 metres and weather changes quickly on the Cuilcagh plateau. The bog is soft and disorientating in low visibility. The trail is excellent in good conditions and genuinely unpleasant in bad ones. Check the forecast before you drive out.

Expecting Blacklion to be part of Northern Ireland

You cross the bridge, you are in the Republic of Ireland. Different currency (euro), different mobile roaming zone for some networks, different speed limit signs (km/h if they weren't already), different VAT. Thirty seconds of walking. The transition is real even if the landscape looks identical.

Getting there.

By car

Enniskillen to Belcoo is 10 miles (16 km) on the A4 - about 20 minutes. The A4 becomes the N16 at Blacklion and continues to Manorhamilton and Sligo. From Sligo town the drive is around 50 minutes via the N16 north. There is no bypass - you pass through the village.

By bus

Translink Ulsterbus Service 64 runs between Enniskillen and Bundoran and stops at Belcoo. Bus Éireann route 66 (Sligo-Manorhamilton-Enniskillen) stops at Blacklion on the south side of the bridge. Between the two services the crossing is reachable without a car, but connections are infrequent - check timetables.

By train

No train service. The nearest stations are Sligo (about 50 minutes by bus) and Enniskillen has no rail link - the nearest Northern Ireland station is Portadown, roughly 90 minutes away.

By air

Belfast International (BFS) is about 1h 40m by car. Ireland West Airport Knock (NOC) is about 1h 15m. Sligo Airport closed commercial services in 2011.
