Fermanagh is the part of Northern Ireland where everything is shaped by water — two big loughs, a hundred and fifty islands, underground rivers cut through limestone, and a town (Enniskillen) sitting on an island in the middle of it. It's the country's quietest county to a visitor and the one I'd happily get stuck in for a week with a kayak.
This is the long version of how I'd spend that week. Or a long weekend. Pick what fits.
How the place sits
Fermanagh's on limestone bedrock, which is why you've got both the surface lakes and the cave systems underneath. Two loughs, joined at Enniskillen:
Upper Lough Erne (south-east of Enniskillen, despite the name) is the narrow, intricate one — channels between reeded islands, sheltered bays, a maze you can paddle for hours without crossing the same water twice. This is where Crom Estate is, and where the otter sightings happen.
Lower Lough Erne (north-west) is the wide one — eighteen miles end to end from Enniskillen to Belleek, opening to proper open water near the western end. Cruising and sailing territory. Devenish, White Island, the bigger crossings are on this lough.
End to end, the system is about fifty miles. You can paddle for a fortnight and not run out of new water.
What to do on the water
Kayaking
The right way to see Lough Erne. The waterline perspective, the quiet, the channels nothing else can get into. Upper Lough Erne — around Crom Estate especially — is the best sheltered paddling in Northern Ireland, in my view, and an absolute matter-of-fact for first-timers. Lower Lough Erne wants a bit more experience because of the open-water crossings and the wind picking up quickly on the wide stretches, but the route across to Devenish from Trory Point is one of the better paddles in the country.
Where to hire / book a session:
- Share Discovery Village (Lisnaskea) — properly kitted out, beginner courses through to multi-day expeditions.
- Erne Tours (Enniskillen) — guided trips to Devenish and elsewhere.
- Castle Archdale Country Park — boats and kayaks to hire, fine for first paddles.
Paddleboarding (SUP)
Has taken over the sheltered bays in the last few years. Most people are stable and moving in half an hour on a modern wide board. Upper Lough Erne is the easy water, the open stretches of Lower Lough Erne are for stronger paddlers and the days the wind isn't up.
Boat tours
- Erne Water Taxi — bookable for whatever route you want.
- Lough Erne Cruises — scheduled cruises with commentary from Enniskillen.
- Kestrel Cruiser — the longer, fancier version with food on board.
The commentary on the scheduled cruises is the bit visitors usually under-rate. Local history, wildlife pointers, the kind of context you'd miss otherwise.
Fishing
Lough Erne is one of Europe's best coarse-fishing waters. Pike (regular catches over 40lb), perch, roach, bream, eels. Permits from tackle shops in Enniskillen and Lisnaskea. Guided trips with kit included available from a few of the operators above.
Sailing and motor-cruising
Lower Lough Erne is the sailing lough. Several clubs on the shores, boat hire from multiple marinas. Manor House Marine near Killadeas runs day-boats up to multi-day cruisers — no licence needed for smaller vessels. A few days on a hired cruiser, mooring at different islands each night, is the closest you'll get to the way the lough was used a hundred years ago.
The islands worth landing on
The islands are the bit that makes Lough Erne specifically Lough Erne. There's a longer island-hopping guide for the deeper version. The shortlist:
Devenish
Best monastic ruins on the lough. A 25-metre round tower (about 82 feet) with its conical cap still intact (rare — most are broken off), St Molaise's Church, Teampull Mór, an intricately carved high cross. Ferry from Trory Point April–September, or paddle across if you're set up for an open-water crossing of about 1.5km. Allow at least 90 minutes to properly do it. Free once you're there.
White Island
Seven carved stone figures in the ruined church — Christian-pagan crossover, dates unclear, the experts still argue. Summer ferry June–August from Castle Archdale Marina. The figures alone are worth the trip.
Boa Island
The unusual one — you drive to it. Bridges at both ends connect it to the mainland. Caldragh Cemetery is the must-see: the Janus figure is one of the oldest stone carvings in Ireland (possibly pre-Christian). Walking trails, small quiet beaches that work for a swim on a calm day.
Inishmacsaint
The quieter monastic island. Smaller jetty on the eastern shore, accessible by your own boat or kayak. Pack lunch.
Marble Arch Caves
If you do one non-water thing in Fermanagh, make it this. The 75-minute guided tour starts on an underground boat along a subterranean river — which sells the experience inside the first three minutes — and walks you through chambers of stalactites, flowstone and chambers I would not call small.
The practical stuff
- Book ahead — weeks ahead in summer.
- Temperature — constant 10°C underground, regardless of what it's doing outside. Bring a layer.
- Footwear — grip. The path is wet in places.
- Allow 2 hours for the tour plus the visitor centre.
- Accessibility — not wheelchair-suitable. Moderate fitness needed, there are stairs and uneven sections.
- Closures — heavy rain floods the river and the tours go off. Check before you drive over.
The wider Marble Arch Caves UNESCO Global Geopark above ground also has the access point for the Cuilcagh boardwalk.
The Cuilcagh boardwalk (the Stairway to Heaven)
Famously photographed, justifiably popular, and the only mountain in Northern Ireland with a wooden staircase up to the bit that matters. About 14.8km return from the Legnabrocky car park — five kilometres of gentle gravel approach track, then the boardwalk and the final 450 wooden steps up to the viewing platform on the edge of the plateau. The platform is the end of the official route. Access beyond the boardwalk to the summit cairn (Cuilcagh proper, 665m) is not permitted.
Allow: 4–5 hours for the full return.
Effort: moderate. The boardwalk does a lot of the work, but it's sustained uphill.
Views: on a clear day, both Erne loughs and parts of five counties. On the days I've done it in cloud, I've seen four metres.
Weather: the summit can be ten degrees colder than the car park and the wind picks up fast. Cloud lowers in twenty minutes from a clear morning. Layers and a forecast.
The Kingfisher Trail (cycling)
Waymarked 480km cycling loop through Fermanagh and across the border into the Republic. The full circuit is a week-plus, Fermanagh holds the best sections for day rides.
Day rides worth doing
Enniskillen to Belleek loop (50km): the northern shore of Lower Lough Erne, through Castle Caldwell Forest and past Boa Island. Quiet roads, lakeside views, fair hills. 3–4 hours.
Upper Lough Erne circuit (30km): the sheltered route through the channels of Upper Lough. Flatter, family-friendly with older children.
Castle Archdale to Kesh (25km one way): past the White Island ferry, through Castle Archdale Country Park, along the Lower Lough shore.
Bike hire
Several places in Enniskillen do hire including e-bikes if the hills aren't your thing. Erne Tours and Share Discovery Village both hire and can advise on routes.
Walks beyond the Stairway
Lough Navar Forest
The drive to the Magho viewpoint alone is worth it — a panorama over the Lower Lough that's the postcard shot. Several waymarked trails from there, the 6km blue trail does the views without too much effort.
Crom Estate
National Trust property on Upper Lough Erne. Trails through ancient woodland and along the shore, with old walls and ruined castle bits scattered about. Some genuinely huge oaks. Wild camping is allowed in designated spots if you book ahead and are an NT member.
Castle Archdale Country Park
Easy lakeside trails (2–5km). Family afternoon walks. The water views and the birdwatching are the draw. Free entry, parking charge.
Enniskillen
The town sits on an island between the two loughs and is the obvious base for any of this. The town itself is a pleasant evening's wander.
What to do in town
- Enniskillen Castle — 15th-century castle housing twin museums (local history and the Royal Inniskilling Fusiliers).
- Forthill Park — climb to the Cole Monument for a 360° view over both loughs.
- The Buttermarket — restored Victorian market with craft shops and cafés.
- Enniskillen Cathedral — old church with a few historical curiosities inside.
- The lakeside walks — paved paths along the lough edge for an evening stroll.
Where to eat in town
- Blake's of the Hollow — Victorian pub barely changed since 1887. Proper pint, often live music.
- The Jolly Sandwich Bar — better than the name suggests. Generous, fresh, busy for a reason.
- The Horseshoe & Saddlers — pub food, regular music sessions.
- Café Merlot — Mediterranean-leaning bistro, good for lunch.
Where to stay
Pick by the activity:
Castles and luxury
Lough Erne Resort — five-star between the loughs, golf and spa attached. The expensive option, justifiable for special occasions.
Belle Isle Estate — castle accommodation on its own island in Upper Lough Erne. The unusual one.
Lakeside lodges and self-catering
Dozens of cottages and lodges scattered around the shores, many with private jetties or boat access. The right shape if you've a kayak or a hired boat. See the County Fermanagh accommodation guide.
B&Bs
Fermanagh is properly good at the traditional B&B. Owners often know what the loughs are doing on a given day better than the operator websites. Packed lunches available if you ask.
Camping
Several campsites round the loughs, Castle Archdale's site is the most-used. Crom Estate has a few wild-camping spots for National Trust members — book ahead. Basic facilities.
Wildlife
Otters
Healthy population on both loughs. Upper Lough is your best chance, particularly at dawn and dusk. The way you spot one is the distinctive line of the body in the water and the high-pitched whistle when there's young. I've watched a family fish off a reed bed for half an hour from a paddle board. That kind of sighting isn't unusual once you're on the water early.
Birds
- Kingfishers — blue flashes along the wooded shores. More common than people think, you need to sit still for ten minutes for one to fly past.
- Herons and egrets — fishing the shallows at first light.
- Great crested grebes — across both loughs, particularly in spring with the display dancing.
- Whooper swans — Iceland winter visitors, October–March, sometimes hundreds.
- Common terns — summer breeders on the islands.
- Cormorants — drying their wings on the marker posts.
The rest
Pine martens in the forests (rare to see but they're there). Red squirrels in Crom's ancient oaks. Bats at dusk over the reed beds. The dragonfly and damselfly numbers on the margins in late summer are properly impressive.
When to come
May–September is peak — warmest, longest days, boats and tours all running. Busy at weekends and school holidays. Midges in calm conditions near water at dawn and dusk, that's the only proper downside.
April and October are the shoulder, quieter, often better weather than people expect. Some boat services run reduced schedules. Autumn light in the forests in October is the bit photographers come for.
November–March is properly quiet. Whooper swans in their hundreds. Most boat tours off. Short days. Marble Arch Caves closed for winter. Only paddle the lough in winter if you've cold-water skills and the right kit.
Practical bits
Getting there
Enniskillen is about 85 miles from Belfast (M1/A4, around 1.5 hours), 80 miles from Dublin (1.5 hours), 50 miles from Sligo and 60 from Derry. Public transport gets you to the town but not really to the activity spots, a car is the way.

Two and three-day shapes
Active two-day weekend
Day 1: morning paddling on Upper Lough Erne (3 hours), afternoon Cuilcagh boardwalk (4 hours), dinner and a session in Enniskillen.
Day 2: Marble Arch Caves morning (2 hours), afternoon a section of the Kingfisher Trail or a drive out to Boa Island for the Janus figure.
Slower three-day
Day 1: arrive, walk Enniskillen, evening cruise on Lower Lough.
Day 2: Devenish in the morning (ferry or paddle), Crom Estate in the afternoon.
Day 3: Marble Arch Caves, then either a Kingfisher Trail section or Castle Archdale and the White Island ferry.
Family week
Easier mix: Castle Archdale walks, SUP lessons on sheltered water, Marble Arch Caves, boat tours to the islands, flatter Kingfisher sections, swimming at Boa, ice cream in town. Enough to keep everyone occupied without burning anyone out.
One closing line
Fermanagh works on a different timer to the coast and the mountains. People who go for a long weekend usually come back for a week.
