Eas a’ Chual Aluinn

Eas a' Chual Aluinn: Britain's Highest Waterfall

Imagine standing at the lip of a high, windswept plateau as a ribbon of water peels away beneath your feet and falls — and falls — for some 200 metres into the wild glen below. This is Eas a' Chual Aluinn, widely regarded as the tallest waterfall in the United Kingdom, hidden deep in the rugged emptiness of Assynt in Sutherland.

It is more than three times the height of Niagara Falls, yet hardly anyone sees it, because there are no shortcuts here. You reach it either by a long, boggy mountain hike to a viewpoint at the top, or by taking to the water and admiring it from below. Either way, this is a waterfall you have to work for.

Here's everything you need to know before you go.

About Eas a' Chual Aluinn

Eas a' Chual Aluinn drops around 200 metres (about 650 feet), which makes it, by most reckonings, the highest waterfall in Britain — taller than the better-known Steall and Falls of Glomach, and more than three times the height of Niagara. Rather than a single column, the water descends in two great steps down dark, ancient Lewisian gneiss cliffs — some of the oldest rock anywhere in Britain — before gathering in the glen and emptying into Loch Beag and Loch Glencoul, a sea loch reaching inland from Kylesku.

One honest word of warning: the flow is highly seasonal. After heavy rain it's a thundering white cascade, but in a dry summer it can dwindle to a thin trickle, and more than a few visitors have made the long walk only to find it disappointing. For the falls at their most dramatic, come a day or two after a good spell of rain.

The setting is pure Assynt — a sparse, glacier-carved wilderness of bare peaks and scattered lochans, with the falls tucked into a steep, lonely glen southeast of Kylesku.

Getting there

The falls can only be reached on foot, or viewed from below by boat, so "getting there" mostly means reaching the trailhead.

By car, the parking area sits at a sharp hairpin bend on the A894 between Kylesku and Lochinver, at the northern end of Loch na Gainmhich — about three miles south of Kylesku, or four kilometres south of Unapool. The grid reference NC281278 (postcode IV27 4HW covers the wider area) will get you close; coming from the Kylesku side, you'll pass the Wailing Widow Falls just before the bend.

Public transport is very limited out here. Buses serve Kylesku and Lochinver, but there's no easy onward link to the trailhead, so check the current timetables and plan carefully.

There's also a wonderful alternative to the hike: in good weather, seasonal boat trips run from the pier at Kylesku across Loch Glencoul, giving a superb view of the falls from below. Check the operators' current schedules, as sailings are weather-dependent.

If you're coming from further afield, public transport to the trailhead is very limited, so visitors arriving without a car often prefer to let a local driver handle the journey.

Where does the name come from?

The name is an anglicised version of the Scottish Gaelic Eas a' Chùil Àlainn — "the waterfall of the beautiful tresses" — a lovely image of the long, flowing strands of water draping down the cliff. It's pronounced, very roughly, "es-a-kohl-a-loo-un," and some link the name instead to nearby Glencoul.

There's no famous legend attached to the falls themselves; here, the poetry is in the name and in the sheer, lonely grandeur of the place.

The walk and the trails

From the hairpin-bend car park, the route follows an old track around the northern end of Loch na Gainmhich. Early on you reach the Wailing Widow Falls, where you cross the outflow on stepping stones — these can become impassable after very wet weather, in which case a second path loops around the south side of the loch. Beyond, the way crosses open, boggy moorland to a vantage point near the top of the falls.

Three things are worth knowing before you set out, because this walk catches people out.

First, the path is not signposted and frequently vanishes into deep bog, so an Ordnance Survey map (Explorer 442) and a compass — and the skill to use them — are essential. Phone signal is non-existent.

Second, there's a companion waterfall, Eas-an-t-Sruth Ghil, on the opposite side of the valley that is easily mistaken for the main falls; many walkers turn back at it, never seeing the real thing. To reach Eas a' Chual Aluinn you need to cross the final stream.

Third, because the cliff is so high and so sheer, you only get a partial, foreshortened glimpse from the top — and the edge is genuinely lethal. Never go right to the lip of the plateau or try to climb beneath the falls. The full sweep of the drop is best appreciated from below, on the boat.

Parking

There's a small parking area at the sharp hairpin bend on the A894, at the northern end of Loch na Gainmhich (grid reference NC281278, around three miles south of Kylesku). It holds only a handful of cars, with a rougher overflow space just to the south if it's full, and it's roughly 300 metres from there to the start of the path. No parking charge is signed, but it's worth checking on-site. Spaces go quickly in summer, so arrive early.

Facilities

Make no mistake: this is genuine wilderness. There are no toilets, no café and no shops at the falls or anywhere along the walk, and no mobile signal once you leave the road. You must set out completely self-sufficient.

The nearest facilities are along the coast — Kylesku, and the larger villages of Lochinver and Ullapool, have shops and somewhere to eat. Fuel stations are sparse in this corner of the Highlands, so top up in Ullapool or Lairg, and fill your water bottles before you start walking.

Things to know before you go

Best time to visit. Aim for late spring to early autumn for the most settled weather and longest daylight, but remember the flow is seasonal — the falls are far more impressive after rain, and can be a mere trickle in a dry spell. Spring snowmelt brings fuller water, while April often means quieter roads and fewer midges.

Midges. On still, damp summer days the Highland midges can be relentless, so pack repellent and a head net.

Dogs. Dogs should be on a lead for the livestock and the cliff edges — but think hard about whether yours can handle a rough six-mile bog walk.

Accessibility. This is not an accessible site in any sense: it's a long, rough, trackless mountain walk over wet ground, unsuitable for wheelchairs or pushchairs.

Navigation and safety. This matters more here than at almost any waterfall in Britain. Carry an OS map and compass (there's no phone signal), tell someone your plans and expected return, and avoid the walk in mist or low cloud, when it's dangerously easy to lose the path. Keep well back from the plateau edge, never attempt to descend beneath the falls, and treat winter as a full mountaineering outing needing the right kit and skills. It's no place for young children or first-time hillwalkers.

Swimming. No — this is a remote, cold and dangerous glen with sheer drops, not a bathing spot. Enjoy it from a safe distance.

Where to stay

Because the falls are so isolated, a comfortable coastal base and an early start make all the difference.

The harbour village of Lochinver, around twenty miles to the south, is the nearest place with a decent range of accommodation, plus shops and a famous little pie shop to fuel up at.

For a wider choice and the best transport links, the busy port town of Ullapool, further south down the coast, is the main hub of the north-west and an excellent base for exploring Assynt and the North Coast 500.

What to pack

This is a serious wilderness hike, so pack properly — your safety can depend on it.

• A pair of waterproof walking boots, as the peat-hag ground is wet and muddy even in summer.
• A waterproof jacket and trousers and warm layers; the weather turns fast.
• A reliable compass — the path is unmarked and there's no phone signal.
• A set of walking poles for the rough, boggy and uneven going.

Add an OS Explorer 442 map, a midge net, a power bank, plenty of water and high-energy snacks, and a first-aid kit, and you'll be well set.

Photography tips

Eas a' Chual Aluinn is a tricky but rewarding subject. From the top you can capture only part of the falls, framed by the plateau and the glen — and you must do it from a safe distance back from the edge. For the full height, the boat trip on Loch Glencoul gives the classic view from below.

Visit after rain for the strongest flow and the moodiest atmosphere, aim for the soft light of early morning or late afternoon, and bring a tripod for long exposures and a waterproof cover for the ever-present spray and Highland drizzle. Above all, never put yourself near the edge for a shot — no photograph is worth it.

Conclusion

Eas a' Chual Aluinn is the kind of place that rewards the determined and humbles everyone. The tallest waterfall in Britain, it hides itself away in the ancient wilderness of Assynt, asking you to either earn it across miles of bog or come at it sideways from the water — and even then, only ever showing you part of itself from the top. Time your visit for after the rain, go properly prepared, and this elusive Highland giant will repay every step.
