What’s the Biggest Waterfall in the UK?

If you’ve ever stood at the base of a thundering waterfall, you’ll know the feeling: raw power, spray hitting your face, and the sense that nature is showing off. The UK might not have the giant falls of Iceland, Canada, or South America, but it does have some seriously impressive cascades — from remote Highland plunges to beloved Welsh wonders.

So, what’s the biggest waterfall in the UK?

The short answer is Eas a’ Chual Aluinn in Scotland, which drops a staggering 200 metres (658 feet) — more than three times the height of Niagara Falls. But the full story is more nuanced. Some waterfalls boast greater volume, some are easier to reach, and some win hearts for their beauty rather than sheer height.

This guide explores the tallest, most famous, and most accessible waterfalls across the UK, while giving you practical hiking tips and gear advice for your next adventure.

Eas a’ Chual Aluinn – Scotland’s Remote Giant

• Height: 200m (658ft)

• Location: Assynt, Sutherland, Northwest Scotland

When it comes to raw height, nothing in the UK beats Eas a’ Chual Aluinn (pronounced “ess-a-hool-oon”). This monster drop towers above its rivals and is widely accepted as Britain’s tallest waterfall.

The problem? It’s not exactly easy to get to. To see it up close, you need to commit to a demanding 10km hike across boggy, uneven Highland terrain, often with wet feet and unpredictable weather. The alternative is a boat trip from Kylesku across Loch Glencoul, which delivers a breathtaking view of the falls from the water.

On a rainy day, Eas a’ Chual Aluinn thunders like a white ribbon tearing down the cliffs. On a dry day, it shrinks to a trickle — still majestic, but proof of how much UK waterfalls rely on rainfall.

If you’re chasing solitude, remote landscapes, and a genuine wilderness experience, this is the crown jewel. Pack properly: waterproof boots, trekking poles, and a 30L backpack with hydration system will make the hike far more manageable.

Falls of Glomach – The Highland Powerhouse

• Height: 113m (370ft)

• Location: Kintail, Ross-shire, Scotland

The Falls of Glomach don’t reach the dizzying height of Eas a’ Chual Aluinn, but they arguably pack more drama. “Glomach” means gloomy in Gaelic — fitting for a deep, shadowy ravine where the waterfall plunges with incredible force.

Reaching Glomach isn’t a casual stroll. Expect a strenuous 12km hike from the nearest road, winding through the mountains of Kintail. But the reward is epic: a sheer vertical plunge into a rocky chasm that feels raw and untamed.

Many hikers consider Glomach to be the most atmospheric waterfall walk in Britain — wild, challenging, and unforgettable. If you bring a tactical rucksack with water bladder pouch, you’ll thank yourself on the long approach.

Pistyll Rhaeadr – The Pride of Wales

• Height: 73m (240ft)

• Location: Llanrhaeadr-ym-Mochnant, Powys, Wales

If Eas a’ Chual Aluinn is remote and Glomach is dramatic, Pistyll Rhaeadr is the waterfall of the people. Known as one of the “Seven Wonders of Wales,” this single-drop cascade combines accessibility with beauty.

Unlike the Scottish giants, Pistyll Rhaeadr has a car park and café nearby, making it one of the easiest “big” falls to visit. Mist often rises in the valley, rainbows appear in the spray, and the wooded surroundings add a mystical touch.

It may not be the tallest, but in terms of charm, Pistyll Rhaeadr more than holds its own. Families, photographers, and casual walkers flock here year-round.

High Force – England’s Most Famous Waterfall

• Height: 21m (70ft)

• Location: River Tees, County Durham

England doesn’t have waterfalls on the scale of Scotland or Wales, but High Force makes up for it with sheer power. After heavy rain, the River Tees hurls itself over a limestone cliff in a dramatic torrent.

It’s smaller in height but big in reputation — probably the most famous waterfall in England. Its easy access makes it a favourite for family trips and photographers.

Other Notable UK Waterfalls

• Steall Waterfall (Glen Nevis, Scotland): A 120m single drop set in one of Scotland’s most photogenic valleys, near Ben Nevis. Famously featured in Harry Potter and the Goblet of Fire.

• Aber Falls (Snowdonia, Wales): A 37m plunge in the Carneddau mountains. Particularly beautiful in spring with wildflowers and mist.

• Ingleton Waterfalls Trail (Yorkshire, England): A 7km circular walk past a chain of stunning smaller falls including Thornton Force.

• Causeway Coast Falls (Northern Ireland): A series of coastal cascades that add to the magic of the UNESCO-listed Giant’s Causeway.

So, What’s the Biggest Waterfall in the UK?

By measurement, the clear winner is Eas a’ Chual Aluinn in Sutherland, Scotland at 200m.

But if you ask hikers which waterfall feels the “biggest” in terms of impact, atmosphere, and adventure, you’ll hear arguments for Falls of Glomach and Pistyll Rhaeadr.

And for sheer popularity, High Force probably sees more annual visitors than any other UK waterfall.

Hiking to See the UK’s Waterfalls

Visiting these natural wonders is rarely just a roadside stop — more often, it’s a proper hike. Here’s how to prepare.

1. Wear the Right Footwear

Even shorter waterfall trails can involve mud, slick rocks, and ankle-twisting steps. Waterproof boots with good grip are a must.

2. Pack Smart

A 30–35L backpack with waterproof lining will hold snacks, spare layers, and a camera. If it includes a water bladder pouch, even better — hands-free hydration keeps you moving.

3. Plan for Weather

Rain makes waterfalls more impressive but also more dangerous. Trails can flood, rocks turn greasy, and rivers swell. Always check forecasts and avoid risky crossings.

4. Start Early or Late

Popular falls like Pistyll Rhaeadr and High Force get crowded midday. Dawn and dusk visits mean fewer people and better light for photography.

5. Respect Nature

Stay on marked trails, don’t scramble onto wet rocks near the falls, and leave no litter. These landscapes are fragile and deserve protection.

The Gear That Makes Waterfall Adventures Easier

When you’re out chasing Britain’s biggest waterfalls, the right gear transforms a hard slog into an enjoyable adventure.

• Backpacks: A 30L waterproof backpack with adjustable straps and breathable mesh keeps your gear dry and comfortable. A lightweight tactical rucksack with a 2L hydration bladder means you never need to stop for a sip.

• Clothing: Layers are essential — a lightweight waterproof jacket, base layer, and quick-dry trousers keep you prepared for sudden changes.

• Accessories: Walking poles reduce strain on descents, while a head torch is handy for late finishes. Bike accessories for men like compact repair kits or helmet storage clips can also double up for hiking pack add-ons.

Recovery After the Hike

Waterfall walks often mean hours on your feet, steep climbs, and heavy descents. Recovery matters just as much as preparation.

That’s where nutrition and hydration tools like protein bottles and shakers come in.

• 600ml protein shaker bottle – Ideal for a recovery shake on the go.

• Protein shake bottle mixer – Smooth blends without clumps.

• Black protein bottle shaker – Durable and stylish for daily use.

• Protein shaker 500ml – A compact option for shorter hikes.

• Protein shaker easy clean – Saves hassle after a long trek.

Whether you’re refuelling with whey protein chocolate, a vegan shake, or an electrolyte drink, having a quality protein shaker cup makes recovery simple.

Final Thoughts

The UK’s biggest waterfall by height is Eas a’ Chual Aluinn, but depending on how you define “biggest,” contenders like the Falls of Glomach, Pistyll Rhaeadr, and High Force all make the list. Each offers its own mix of drama, accessibility, and atmosphere.

Chasing these falls isn’t just about the destination — it’s about the adventure along the way. With the right preparation, gear, and a sense of curiosity, hiking to the UK’s waterfalls can be one of the most rewarding outdoor experiences you’ll ever have.
