The Fermanagh Lakelands — Water, Caves, and Wide Open Skies
County Fermanagh is Northern Ireland's lake district — a landscape of island-studded loughs, underground rivers, and skies so wide they feel continental. Upper and Lower Lough Erne between them hold over 150 islands, some with monastic ruins dating back to the sixth century. It is the least visited county in Northern Ireland, which means you get all of this largely to yourself.
Belfast to Enniskillen — the county town and natural base — takes about ninety minutes on the A4. The road west crosses the heart of Northern Ireland through Dungannon and past the Clogher Valley, and the landscape gradually opens up into the lakeland basin.
Marble Arch Caves
A UNESCO Global Geopark site and one of the finest show caves in Europe. An underground boat ride takes you along a subterranean river through vast chambers of stalactites and stalagmites. The cave system extends for miles beneath the Cuilcagh Mountains. Guided tours run daily from March to October and last about 75 minutes. Book ahead in summer.
Cuilcagh Boardwalk — The Stairway to Heaven
A wooden boardwalk climbing the slope of Cuilcagh Mountain to a viewing platform at 665 metres with panoramic views across the lakelands and into County Leitrim in the Republic. The walk is about 7.5 km each way from the car park. It went viral on social media and now attracts visitors from around the world. Go early or midweek to avoid queues.
Lough Erne
Upper and Lower Lough Erne together form a vast waterway stretching almost the full length of the county. Devenish Island on Lower Lough Erne has a beautifully preserved round tower and monastic ruins from the sixth century — accessible by ferry from Trory Point. Boa Island has enigmatic stone figures (the Janus figure) that predate Christianity. If you prefer mountains to lakes, the Mourne Mountains are under two hours east and make a perfect contrast.
Enniskillen
The county town sits on an island between Upper and Lower Lough Erne. Enniskillen Castle houses two museums covering the county's history from prehistoric times to the present. The town centre is compact and walkable with excellent restaurants, traditional pubs, and a weekly market. A natural base for exploring the lakelands.
Getting There
The A4 from Belfast is the fastest route — about 90 minutes to Enniskillen. Alternatively, come via the scenic A32 through Omagh. Fuel stations are plentiful. The lakelands reward a two-night stay — one day for the caves and boardwalk, another for the islands and Enniskillen.
