Discover one of Ireland's best-kept secrets: a seven-day loop through County Fermanagh, from Enniskillen's island town to underground caves, a Georgian mansion, and 2,000-acre lakeside estates on the shores of Lough Erne.
If there is a corner of the British Isles that genuinely surprises people, it is County Fermanagh. Landlocked in the west of Northern Ireland, Fermanagh is defined by water. The two connected bodies of Lough Erne, linked by the River Erne, create a landscape of wooded islands, hidden inlets, and drumlin-dotted shorelines that feels far removed from the more-visited north coast.
The Erne Circuit is a seven-day loop that starts and ends in Enniskillen, the county town. From there it tracks north-west along the shores of Lower Lough Erne to the pottery village of Belleek, swings south through the UNESCO Geopark to the Georgian grandeur of Florence Court and the underground marvel of Marble Arch Caves, then heads east along Upper Lough Erne to the National Trust estate at Crom before returning to the start. The total driving distance is around 147 km. None of the legs takes more than an hour. The days are long, the roads are quiet, and the scenery rewards patience.

Enniskillen is the only island town on the entire island of Ireland. The town sits on a ridge of land between Upper and Lower Lough Erne, with the River Erne flowing on both sides. It is a practical base but also a worthwhile destination in its own right.
Enniskillen Castle, built almost 600 years ago by the ruling Maguire clan, now houses two museums: the Fermanagh County Museum and the Inniskillings Museum, covering the history of the county and the British Army's most famous Irish regiment. Castle Coole, a pristine Neo-Classical mansion designed by James Wyatt and completed in 1798, sits 10 minutes south of the centre and ranks among the finest Georgian houses in Ireland. National Trust members get free entry to both.
The unmissable excursion is the water taxi to Devenish Island, two kilometres downstream on Lower Lough Erne. The round tower at Devenish dates to the 12th century and stands nearly 30 metres tall, still essentially complete. The ruined abbey, high cross fragments, and early Christian carved stones make this one of the most atmospheric monastic sites in Ireland. Erne Water Taxi runs guided departures from Enniskillen; booking ahead in July and August is advisable.
Eight days through the finest UNESCO towns of Bohemia and Moravia: Prague's Astronomical Clock, the bone church of Kutná Hora, Telč's Renaissance square, the fairy-tale castle bend of Český Krumlov and Pilsner Urquell in Plzeň.
For the first evening, Blakes of the Hollow on Main Street is a listed Victorian pub that has barely changed since 1887. It is the right introduction to Enniskillen's easy sociability.
The drive north from Enniskillen along the A46 is one of the most understated scenic roads in Northern Ireland. The lake is rarely out of sight as you pass Derrygonnelly and cross onto Boa Island via a short road bridge.
Boa Island's Caldragh Cemetery holds two stone figures that predate Christianity by several centuries. The larger Janus Stone shows two faces pressed back-to-back, thought to represent life and death, or the seen and unseen worlds. The smaller Lustymore Idol was moved here from a nearby island. Both are unguarded, unmarked by crowds, and genuinely strange.
From Boa Island, a short detour into Lough Navar Forest leads to Eagle Rock viewpoint, where a seven-mile forest drive ends in a panorama that takes in the entire width of Lower Lough Erne and the Donegal hills beyond the border.
Belleek, at the north-western tip of the county, has been making Parian china since 1857. The pottery visitor centre is free. Guided factory tours run on weekdays and are worth an hour; you will see the 16-stage handcraft process from clay mixing to hand-painted finishing.
The drive south from Belleek through Derrygonnelly is around 40 minutes, but it leads to one of the most varied two-day stretches on the route.
Florence Court, eight miles from Enniskillen, is a Palladian mansion built by the Cole family in the mid-18th century. The gardens are the main draw, particularly the walled kitchen garden and the Florence Court Yew: the parent tree of all Irish yews (Taxus baccata 'Fastigiata'), grown from a wild specimen found on the estate around 1740. National Trust manages the estate; the house interior is open on selected days.
Three kilometres west, Marble Arch Caves is one of the most active river cave systems in Ireland and the UK. The visitor tour covers 1.5 km and includes a ten-minute underground boat journey along the cave river, passing through passages of stalactites, flowstones, and sculpted limestone that took 330 million years to form. Pre-booking is strongly recommended in summer; tours fill well in advance. The caves are part of the Cuilcagh Lakelands UNESCO Global Geopark, one of only four transnational geoparks in the world.
Save the second day at Florencecourt for Cuilcagh Mountain. The trailhead is a short drive from the caves and the boardwalk trail, nicknamed the Stairway to Heaven, takes four to six hours return. The path climbs through blanket bog and a stepped wooden boardwalk to the summit plateau at 665 metres, with views extending across the entire Fermanagh lakelands, the Erne catchment, and the hills of Sligo and Donegal.
The drive east from Florencecourt to Crom, around 40 minutes via the A4, passes back through Enniskillen, making it a natural stop for fuel or supplies before continuing to the upper lough.
Crom Estate, on the southern shore of Upper Lough Erne, is the largest National Trust property in Northern Ireland: 2,000 acres of ancient woodland, islands, and shoreline centred on the ruins of a 17th-century castle. The ruins are quietly extraordinary, a roofless shell overlooking the water, with the Crighton Tower folly visible on Gad Island opposite. The pair of ancient yews beside the old castle, nearly 400 years old and with a combined circumference of over 100 metres, are among the most impressive trees in Ireland.
The estate has some of the richest biodiversity in Northern Ireland, with red squirrels, barn owls, otters, and rare butterflies recorded. Boat hire and canoe rental are available on-site at peak times. Springwatch filmed from Crom in 2026, so the wildlife credentials are well-established. Free for National Trust members.
The final leg, 30 km north on the A34 and A4, takes around 35 minutes. A slow drive along the Upper Lough Erne shore via Lisnaskea adds lake views before the circuit closes.
Back in Enniskillen, a farewell pint at Blakes of the Hollow, where the bar fittings have barely changed in 140 years, is the right way to finish a drive through one of Ireland's most rewarding and least-visited counties.
May to September is the best window for the Erne Circuit. The Devenish Island ferry runs from July to October; Marble Arch Caves tours operate from mid-March to October (call ahead outside the main season). The Cuilcagh boardwalk is walkable year-round but can be very exposed in winter and waterlogged after prolonged rain.
Enniskillen is around two hours from Belfast and three from Dublin. There is no direct train service to Fermanagh, so a hire car from Belfast, Dublin, or Derry is the practical starting point. Translink buses connect Enniskillen to Belfast and Dublin for those who prefer to arrive by public transport.
This is one of the more affordable driving routes in Northern Ireland. A National Trust membership covers Florence Court, Castle Coole, and Crom Estate at no further cost. Marble Arch Caves charges an entry fee (around GBP 10 per adult in 2025); Belleek Pottery is free. Accommodation ranges from village B&Bs in Belleek and Florencecourt to guesthouses and small hotels in Enniskillen.
