Five Stunning Hidden Waterfalls in the UK

Think you need to go abroad to find jaw-dropping waterfalls? Think again. The UK is home to some of the most breath-taking cascades you’ve (probably) never heard of. Tucked away in woodlands, gorges, and quiet countryside, these hidden gems are perfect for a weekend escape or a magical photo op. Here are five stunning hidden waterfalls in the UK that are well worth the detour:

🌿 1. Pistyll Rhaeadr – Powys, Wales

Where: Near Llanrhaeadr-ym-Mochnant, Powys

Height: 240 feet (73m)

Often overshadowed by Wales' better-known Snowdonia attractions, Pistyll Rhaeadr is the tallest single-drop waterfall in the UK. But what makes it special is the setting—this towering cascade flows over a cliff in a serene, fern-filled valley. The nearby footpath leads you up to the top for a spectacular view across the Berwyn Mountains.

✨ Magical fact: It’s considered one of the Seven Wonders of Wales—and it’s easy to see why.

🪨 2. Grey Mare’s Tail – Moffat, Scotland

Where: Dumfries and Galloway

Height: 200 feet (60m)

Hidden in a rugged glen near the town of Moffat, Grey Mare’s Tail is a dramatic waterfall that plunges from Loch Skeen down into a narrow valley. It’s a bit of a climb to reach it, but the views are breath-taking. Wild goats and peregrine falcons are often spotted in the area.

🎒 Top tip: Bring your hiking boots—there’s a challenging but rewarding trail to the loch at the top.

🌲 3. St Nectan’s Glen – Cornwall, England

Where: Near Tintagel, Cornwall

Height: 60 feet (18m)

Tucked inside an ancient woodland, St Nectan’s Glen feels like a scene from a fantasy novel. The waterfall spills through a hole in the rock into a crystal-clear basin below. Revered by locals as a spiritual place, the glen is filled with ribbons, stones, and other offerings left by visitors.

🌿 Vibe: Mystical, peaceful, and perfect for a quiet moment of reflection.

🧭 4. Eas a’ Chual Aluinn – Highlands, Scotland

Where: Near Kylesku, Sutherland

Height: 658 feet (200m)

This remote Scottish marvel is the tallest waterfall in Britain, but few people ever see it. You’ll either need to hike a demanding 6-mile trail or take a boat across Loch Glencoul to reach it. But if you make the journey, you’ll be rewarded with raw, unspoiled wilderness and a waterfall that plunges dramatically down a sheer cliff face.

🥾 Warning: This one’s for the seasoned adventurer—but it’s truly unforgettable.

💦 5. Henrhyd Falls – Brecon Beacons, Wales

Where: Near Coelbren, Brecon Beacons National Park

Height: 90 feet (27m)

Hidden among lush greenery, Henrhyd Falls is not only beautiful—it’s famous. It doubled as the Batcave in The Dark Knight Rises. The real thrill? You can walk behind the curtain of water and stand in the hollowed rock behind the falls.
