Most Irish waterfalls are fed by spate rivers, which means the same falls can be a roar you hear from the car park or a trickle over wet stone, depending on how much rain fell in the last few days. Torc, off the N71 in Killarney, is the one nearly everyone sees, because it is five minutes from the road and signposted from the ring road. It is worth the stop. But it is also the busiest waterfall in the country by a distance, and the nine below run from car-door cascades to an 80m plunge across seven counties, ranked by what they ask of you in return. If you want the easiest day, start at number one. If you only chase falls after heavy rain, most of this list rewards you and a couple are pointless in a dry spell – those are flagged.
1. Glencar Waterfall, County Leitrim
Glencar Waterfall is the one W.B. Yeats wrote into The Stolen Child in 1889, calling out the ‘wandering water’ of the glen, and it is also the easiest good waterfall in the north-west to reach. The 15-metre drop falls over moss-covered limestone into a fern-lined pool on the western edge of Glencar Lough, about 11 km west of Manorhamilton and a 20-minute drive from Sligo town. Recent upgrades replaced the old muddy tracks with wooden decking and handrails, so the loop from the car park to the viewing platform is short, level and genuinely wheelchair-friendly as far as the platform steps.
There is a tea-shed on site serving coffee and hot food, toilets inside the café building, and a small playground by the picnic area, which makes this the pick of the list if you are travelling with young children. The car park is free but fills before midday on summer weekends, so come early. Dogs are welcome in the car park and café but not on the main waterfall trail. Allow two hours if you want to add the lake shore, and note the falls are at their best after heavy rain, when the gorge fills with mist. In a settled dry week it is still a pleasant walk, just a quieter one.
2. Mahon Falls, County Waterford
Mahon Falls drops 80 metres over ancient sandstone in the Comeragh Mountains, and the reason it earns a high place is that you can see the whole cascade the moment you leave the car park. The main route is a 3 km out-and-back on a well-made gravel path, about 40 to 50 minutes, gently undulating until the last stretch, which turns rocky and finishes on natural stone steps. That constant sight of the falls ahead keeps younger walkers moving, though the loose gravel defeats pushchairs past the first kilometre.
The falls are a graceful, multi-tiered cascade rather than a single torrent, swelling to a misty rush after Atlantic rain and thinning in dry months to show the sandstone platforms underneath. The car park is free and signposted off the N25, a 25-minute drive north of Dungarvan, but it fills fast on sunny weekends – aim for before midday or after 4pm. There are no toilets and no water, so bring your own. On the way in, test the Magic Road just past the car park: a stretch where the camber and surrounding land create a convincing illusion of cars rolling uphill in neutral. It is a harmless trick of the landscape, and children love it.
3. Aasleagh Falls, County Mayo
Aasleagh Falls is a four-metre drop on the River Erriff, just north of the Galway-Mayo border, framed by Ben Gorm and the Devil’s Mother before the river runs on into Killary Harbour, Ireland’s only fjord. Four metres does not sound like much, and in a dry June it isn’t. The Erriff is a spate river, though, so a day or two after heavy rain it turns into a real torrent you can hear from the road. This is where Jim Sheridan shot a fight scene in The Field with Richard Harris, and where David Attenborough came with a BBC crew to narrate the migration of the European eel.
One real warning. Two small lay-bys flank the R335 just past the bridge, holding roughly 40 cars between them, and they sit directly on a sharp, sweeping bend where there have been several near-misses. You have to cross the road to reach the bridge and the viewing area, so keep tight to the edge, watch for oncoming traffic and make eye contact with drivers where you can. Given that crossing and the slippery rock at the base, this is one to leave the dog at home for. Then give it half an hour: the bridge view, the short muddy path to the base, and the start of the Western Way if the legs want more. Leenane, 4 km south, is the place for food.
4. Torc Waterfall, County Kerry
Torc Waterfall is the most visited natural spot on this list, and its 20-metre cascade over 400-million-year-old Devonian sandstone is genuinely good, so the crowds are earned rather than manufactured. It sits just off the N71 Kenmare Road on the western edge of Killarney National Park, with no entry fee, which is most of why it is so busy. A short stone path of around 100 steps climbs from the car park to the main viewing platform in about five minutes, and a second flight opens a wider view across Muckross Lake and the peaks.
The name comes from the Irish Eas an Torca, the waterfall of the wild boar, and local folklore ties the gorge to a man cursed to turn into a boar each night, said to have vanished into the Devil’s Punchbowl above. If you have more than five minutes, keep climbing the second set of steps for the panorama, or take on the Red Trail, a steep flight up to a stone beehive hut that locals call Cardiac Hill for the effort it demands. Two free car parks flank the N71; the main one fills first in summer, so use the larger secondary lot and cross to the trailhead. The stone steps turn slick when damp, so proper footwear matters here even though the walk is short.
5. Glenmacnass Waterfall, County Wicklow
Glenmacnass Waterfall is an 80-metre cascade that plunges in three staggered drops at the head of its valley, high in the Wicklow Mountains on the R115, the old Military Road built between 1801 and 1809 to help British forces patrol the hills after the 1798 rebellion. The drive up over sheep-grazed uplands and peat bog is half the point, and the falls appear on the right if you are heading south from Sally Gap towards Laragh. There is a free car park at the top of the falls, and a handful of pull-outs where you can stop for photographs without leaving the car.
Here is the honest part. There is no formal platform or path from the top car park, so to see the cascade properly you walk a short way back down the R115 – along the narrow, winding roadside of a busy mountain road with no footpath. Walk against the traffic, stay tight to the edge, keep children close and dogs on a short lead. Do not climb the fence near the lip: the drop is severe, the rock is unstable, and there have been fatal accidents where people tried to scramble down the river stones to the base. Break-ins have been reported in this remote car park too, so leave nothing visible in the car. Treated with respect, it is one of the finest falls within an hour of Dublin.
6. Glenevin Waterfall, County Donegal
Glenevin Waterfall drops about 12 metres over dark volcanic rock into a clear pool in a sheltered glacial valley near Clonmany, on the Inishowen Peninsula. The walk in is the appeal: a mostly flat, gravel-surfaced, out-and-back trail through mature woodland and fern banks, straightforward for families and manageable with a sturdy pushchair, though occasional stepping stones and uneven patches mean it is not fully paved. The sound of the water builds as you approach.
The plunge pool at the base is a local swimming spot in warmer months, but there are no lifeguards, the rock edges are slick with algae, and the water rarely climbs above 12°C even in August, so treat a dip with caution and keep children supervised. A small car park sits beside the Glen House, which runs a tea room for hot drinks and cake, with public toilets near the main parking. One seasonal note: the woodland floor can carry ticks in spring and summer, so long trousers and a check afterwards are sensible. Fold it into the Inishowen 100 loop for a full day.
7. Tourmakeady Waterfall, County Mayo
Tourmakeady Waterfall falls in three tiers, the final drop about 9 metres into a pool 6 to 8 feet deep, set inside a mature woodland on the edge of Lough Mask in south-west Mayo. This is a quieter, less-trodden stop than the marquee falls, and the draw is the walk as much as the water: native oak, ash, rowan and birch, with bluebells spreading across the floor in spring. The trails are clearly marked with purple waymarkers, free, and open around the clock.
There are two ways in: a 2.2 km route of 30 to 45 minutes from the trailhead car park, or a longer 4 km walk from near the community centre in the village, roughly 1 to 1.5 hours. A 3.9 km loop links the two if you want the full circuit, graded easy with about 80 metres of climbing. The car park is small, so come early on weekends and school holidays, and there are no toilets or refreshments on site. Stick to the purple markers to avoid straying onto private forestry tracks, and expect muddy paths after rain, when the flow is at its most dramatic. Aasleagh Falls is a short drive north if you want to pair two Mayo cascades in a day.
8. Mare’s Tail Waterfall, County Cork
Mare’s Tail Waterfall is the tallest single-drop cascade in Ireland, plunging 55 metres over a sheer limestone cliff on the western edge of the Beara Peninsula, about 4 km outside Adrigole. The name comes from the way the water fans out as it hits the basin below, spreading like a flicking horse’s tail. There is a catch, and it is the reason this one sits near the end: the falls are on private land, so there is no path to the base. You view them from a designated pull-out on the R572, at an angle that gives an unobstructed look at the plunge against the mountains behind.
The roadside stop is quick, but the better approach is the Beara Way, a 15 km section from Adrigole harbour to the viewpoint that was upgraded under the Outdoor Recreation Infrastructure Scheme with clearer signage and better surfacing. It is graded easy to moderate, through pasture and quiet lanes, and it ends at the same public viewpoint – the final stretch to the water stays on private property. Parking at the pull-out is limited and the road is single-lane, so use the marked bays only and never block the passing lane. Like most falls here it thins to a trickle in a dry summer, so this is one to save for after rain, when the spray throws rainbows above the rock pool. There is no member image for this waterfall.
9. Assaranca Waterfall, County Donegal
Assaranca Waterfall drops about four metres down a dark, moss-covered rock face on the coast road west of Ardara, and the whole appeal is that you watch it without leaving the tarmac. The lay-by sits a few feet from the base, which makes it the most accessible waterfall on the list for anyone with limited mobility – the view is there the moment you open the car door. It is also the most weather-dependent. After a couple of days of rain the water gushes off the top with a roar you can hear from the car; in a settled dry spell it shrinks to a thin run over wet stone and is not worth a detour.
The falls go by a few names – locals say Ardara Waterfall as often as Assaranca, and the Irish Eas a’ Ranca is usually rendered as the waterfall of the great mouse, a name nobody round Ardara can quite explain any more. Parking is a free roadside lay-by with room for about ten cars, quiet most of the year but tight on summer weekends; if there is no space, come back later rather than block the narrow road. There are no facilities of any kind, so sort toilets and food in Ardara or Donegal Town first. The best plan here is to go after rain and pair it with Maghera Beach and its caves, two to five minutes further west on the same road, timing the caves for low tide. You can see the lot inside an hour.
One rule for all nine
The single most useful thing to know about Irish waterfalls is that the forecast matters more than the map. A spate falls that underwhelms in July can be thunderous the day after a downpour, so if you are driving out specifically for the water, check Met Éireann and go in the day or two after heavy rain. The rock at the base is slippery at every one of these sites, and the two roadside falls, Aasleagh and Glenmacnass, ask you to cross or walk a busy road with no footpath – treat those with real care. If you want the easiest day with the biggest payoff, pair Glencar’s boardwalk with the tea-shed and let the harder, higher falls wait for the next wet spell.
