What’s the Biggest Waterfall in the UK?

Planning a Hike to See the UK’s Waterfalls

 

When you think of the UK’s wild landscapes, rolling hills, rugged coastlines, and ancient forests often come to mind. But tucked away in the mountains and glens are some of the most dramatic waterfalls you’ll ever see. From roaring cascades plunging hundreds of feet, to gentle veils trickling down mossy cliffs, Britain is home to hundreds of spectacular falls.

But here’s the big question: what is the biggest waterfall in the UK?

The answer depends on how you define “biggest” — tallest single drop, overall height, or sheer volume of water. Let’s break it down and explore the UK’s most impressive waterfalls.

 

The Contenders for the UK’s Tallest Waterfall

 

There’s long been debate among hikers and geographers over which waterfall deserves the crown. Unlike countries such as Norway or Iceland, where records are well-documented, the UK’s waterfalls are often measured differently. Still, three names always rise to the top:

 

• Eas a’ Chual Aluinn (Scotland)

• Falls of Glomach (Scotland)

• Pistyll Rhaeadr (Wales)

 

Let’s look at each in turn.

 

Eas a’ Chual Aluinn – Scotland’s Remote Giant

 

• Height: 200 metres (658 feet)

• Location: Assynt, Sutherland, Northwest Scotland

 

Eas a’ Chual Aluinn (pronounced ess-a-hool-oon), near Kylesku in Sutherland, is often cited as the tallest waterfall in the UK. It plunges a staggering 200 metres — more than three times the height of Niagara Falls.

But here’s the catch: it’s extremely remote. To reach it, you need to commit to a challenging hike across boggy, rugged terrain, often in unpredictable Highland weather. Another option is to take a boat trip from Kylesku to view the falls from Loch Glencoul — but this depends on conditions.

On a wet day, the falls thunder down the cliffside in a spectacular white torrent. On a dry day, it can shrink to a delicate trickle. Either way, the sheer height is unmatched.

For adventurers chasing solitude and raw natural drama, Eas a’ Chual Aluinn is hard to beat.

 

Falls of Glomach – The Highland Powerhouse

 

• Height: 113 metres (370 feet)

• Location: Kintail, Ross-shire, Scotland

Not quite as tall as Eas a’ Chual Aluinn, but arguably more dramatic in terms of volume and accessibility, the Falls of Glomach are another Highland gem.

The name “Glomach” means “gloomy” in Gaelic — fitting, given the deep, shadowy ravine into which the water crashes. The force and narrow plunge make it one of the most atmospheric waterfalls in the UK.

Reaching the falls involves a strenuous 12km hike from the nearest road, weaving through the mountains of Kintail. Once there, the view is unforgettable: a sheer vertical drop surrounded by cliffs and moorland.

Many hikers consider Falls of Glomach to be the most epic waterfall walk in Britain — less remote than Eas a’ Chual Aluinn, but still a serious adventure.

 

Pistyll Rhaeadr – The Pride of Wales

 

• Height: 73 metres (240 feet)

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

 

While not as tall as the Scottish giants, Pistyll Rhaeadr is often described as one of the Seven Wonders of Wales — and for good reason.

This single-drop cascade flows gracefully down a cliff into a lush valley, surrounded by forest and hiking trails. Unlike the remoteness of Eas a’ Chual Aluinn or the grueling trek to Glomach, Pistyll Rhaeadr is easily accessible by road, with a car park and café nearby.

Its beauty, accessibility, and cultural significance make it one of the UK’s most beloved waterfalls. Many visitors claim it has a mystical atmosphere, with mist rising and rainbows forming in the spray on sunny days.

 

Other Notable Waterfalls Across the UK

 

While the “big three” usually steal the limelight, the UK is scattered with other remarkable waterfalls worth mentioning:

 

High Force – England’s Most Famous

 

• Height: 21 metres (70 feet)

• Location: River Tees, County Durham

 

Though much shorter, High Force is arguably the most famous waterfall in England. It pours with tremendous volume over a limestone cliff, especially impressive after heavy rainfall. It’s easy to access and a favourite for family day trips.

 

Ingleton Waterfalls Trail – Yorkshire

 

• A 7km circular walk featuring a series of smaller but stunning cascades, including Thornton Force and Pecca Falls.

 

Steall Waterfall – Glen Nevis, Scotland

 

• Featured in Harry Potter and the Goblet of Fire, Steall Falls is Scotland’s second-highest single drop waterfall at 120 metres. It’s set in a dramatic glen near Ben Nevis.

 

Aber Falls – Snowdonia, Wales

 

• A beautiful 37-metre fall in the Carneddau mountains, reached by a pleasant hike. Known for spring wildflowers and rainbow mists.

 

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

 

Strictly by measurement, the title goes to Eas a’ Chual Aluinn in Sutherland, Scotland — a towering 200m plunge.

However, if you measure “biggest” by impact, accessibility, and popularity, places like Falls of Glomach, Pistyll Rhaeadr, and High Force might feel more impressive to the average visitor.

In short: the UK’s waterfalls don’t compete on size with the giants of Iceland or Africa, but they pack drama, atmosphere, and a sense of discovery — especially when you’re out in the wild and stumble across one after a long hike.

 

Hiking to See the UK’s Waterfalls

 

Chasing waterfalls in the UK often means venturing into the hills, moors, and forests. Here are some tips to make the most of it:

 

• Check the weather: Heavy rain makes waterfalls spectacular, but also makes paths slippery and streams harder to cross.

• Wear proper footwear: Even “easy” walks can involve mud, rocks, and water crossings.

• Pack smart: A lightweight waterproof jacket, snacks, and water are essentials.

• Go early or late: Popular falls like Pistyll Rhaeadr and High Force can get crowded.

• Respect nature: Stick to trails, and don’t climb near the falls — wet rocks are treacherous.
