Crois Domhnaigh · Co. Cavan

The crossroads before the lake. Everything good is just beyond it.

Crossdoney sits six kilometres west of Cavan town on the R201, at the point where the road forks and the drumlin farmland starts to open into the lake country. It is a crossroads village in the original sense — a handful of houses, a church, a school, built around the junction rather than around any single purpose. The 2022 census counted around four hundred people. It feels honest about what it is.

The reason the name comes up is what sits on either side of it. To the west, Killykeen Forest Park — six hundred acres of mixed woodland on the shore of Lough Oughter, with walking loops that run along the lakeshore between wooded peninsulas and out to viewpoints where the castle appears in the middle of the water. To the north, the lake system itself: Lough Oughter is not really one lough but a drowned drumlin landscape, a maze of small islands, channels and reed beds that spreads for miles through the upper Erne catchment. It is a Special Area of Conservation and one of the quieter corners of Cavan.

In the middle of the lough, on a crannóg barely big enough to hold it, stands Cloughoughter Castle. The O'Reillys built a circular tower house there in the 13th century and used it as a stronghold for three hundred years. In November 1649, Owen Roe O'Neill — the Confederate general who had beaten the Scots at Benburb three years earlier — died of fever inside those walls, with the Cromwellian conquest already past stopping. The castle fell to Cromwellian artillery in 1653. The walls are still standing, half-ruined on their island, and the best way to reach them is by canoe from Killykeen.

Come here if you want the lake country without the Cavan town traffic. Stay for a morning. Walk the Killykeen loops. Paddle out to the castle if you have the gear or can hire it. Drive back through the village and you will have had a full Cavan day from a place most maps skip entirely.

At a glance.

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

01 Lough Oughter

A flooded drumlin landscape, not quite a lake.

Lough Oughter is a maze of channels, small islands and connecting loughs that runs west and north of the village. It is a Special Area of Conservation. Otters, kingfishers, whooper swans in winter. Best understood from the water or from the forest edge at Killykeen.

Walks & outings → 02 Cloughoughter Castle

A round tower on its own island in the lough.

A 13th-century O'Reilly stronghold sits on a crannóg in the middle of Lough Oughter. Owen Roe O'Neill died there in November 1649, three months after Drogheda. The walls are still standing. You get to them by canoe.

Stories & lore → 03 Killykeen Forest Park

600 acres of forest on the lakeshore.

Coillte's flagship Cavan park is five minutes west of the village. Mixed woodland, lakeshore walking loops, chalets that book out in summer. The view of Cloughoughter from Inishconnell pier is the one you came for.

November 1649

Owen Roe at Cloughoughter

Owen Roe O'Neill was the most capable Irish commander of the 17th century. At Benburb in June 1646 he destroyed a Scots Covenanter army of six thousand men, the greatest Gaelic Irish battlefield victory in a century. By 1649, with Cromwell's army in Drogheda and Wexford, the political situation had collapsed around him. O'Neill was sick — the nature of the illness has been argued about ever since, contemporaries suspected poison — and being moved between Confederate-held positions across Ulster. He was brought to Cloughoughter Castle on Lough Oughter and died there on 6 November 1649. He was sixty-three, and the war was effectively over. The castle held out until 1653, when Cromwellian artillery finally forced the surrender. It is the last Gaelic stronghold to fall in the War of the Three Kingdoms.

A lake that is mostly islands

Lough Oughter

Lough Oughter is not really a single body of water. It is a flooded drumlin landscape — the glaciers left a maze of small hills, the Erne valley flooded around them, and the result is an archipelago of islands, channels and connecting loughs covering thousands of acres in west and north Cavan. More than a hundred islands. The system is a Special Area of Conservation and a Special Protection Area, important for breeding waterfowl — great crested grebes, tufted ducks, little grebes — and for the white-clawed crayfish that live in the shallows. In October the whooper swans come in from Iceland. Otters are common; they are just rarely where you are looking. The best way to understand the scale is from a canoe.

How to get there

The island castle

Cloughoughter Castle sits on a crannóg — a small artificial or modified island — that the O'Reillys improved and built on from the 13th century. The circular plan is unusual for an Irish tower house; it owes more to Anglo-Norman keeps than to the rectangular Gaelic hall-house. The castle passed between the O'Reillys, the English crown and various other claimants across three centuries of Cavan's wars. By the time Owen Roe died there in 1649 it had been a prison for the Bishop of Kilmore as well as a garrison. The walls — roofless but largely intact to corbel level — are now protected. There is no public boat service. Canoes and kayaks can be hired at Killykeen. The crossing is short: a few hundred metres of flat, usually calm water.

Things to do outside.

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

Killykeen Forest Park — main lakeshore loop From the main car park, out along the Lough Oughter shore, across the wooden footbridges between the wooded peninsulas, and back through the conifer stands. Flat, well-marked. The view of the castle opens up at the mid-point. Do it before noon in summer — it fills up by afternoon.

Cloughoughter viewpoint at Inishconnell Drive to the small lay-by at Inishconnell on the south shore of the lough. Walk down to the pier. The castle sits on its crannóg a few hundred metres offshore — close enough to photograph properly, too far to reach without a boat. Bring binoculars.

Killykeen short lakeshore loop The compact version, staying on the south side of the park. Mostly tarmac. Good for an hour before lunch, or with younger children who won't manage the full loop.

Cloughoughter by canoe Canoe hire is available at Killykeen. Paddle across to the crannóg, walk the castle perimeter, come back. The lough is usually calm but exposed in a south-westerly. The castle itself is an open ruin — no visitor centre, no entrance fee, no facilities. Bring your own lunch.

When to go.

There is no bad time. There are different times.

Spring

Mar–May

Bluebells in the Killykeen oakwood in April. The lough still, the birds back at the nesting sites, the chalets half-empty. The best window before it gets busy.

◉ Go

Summer

Jun–Aug

The chalets fill up and the park gets weekend traffic. Still worth it — the long evenings on the lakeshore are hard to argue with — but book anything in advance and go early in the day.

◐ Mind yourself

Autumn

Sep–Oct

The forest turns copper and the lough goes still. Whooper swans arrive in October. The hire-boat crowd is gone. This is the right season.

◉ Go

Winter

Nov–Feb

The chalets close, Killykeen stays open. The forest in low light is worth the cold and the mud. Bring proper boots and low expectations of anything being open.

◐ 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.

Trying to land on Cloughoughter island without a canoe

There is no public boat service and no bridge. The crannóg has unstable masonry and protected nesting birds. Paddling over in a hired canoe is the right way. Attempting to wade, swim or improvise is not.

Treating the village as a destination in itself

Crossdoney is a crossroads with about four hundred people. There is nothing to do in the village. Everything here is about the lake and the forest, five minutes down the road. Drive through and you have missed the point.

Doing Killykeen in an hour and calling it done

The loops take longer than they look on the map. The point is the slowness and the water, not covering ground. Give it a half day. If you have a canoe, give it a full one.
