7 Best Zip Lines in Wales (2025)

Zip World Velocity

The fastest zip line in the world. 100mph over a flooded quarry. It lives up to the hype.

Velocity is the headliner — the fastest zip line in the world and the longest in Europe at 1.5km. You fly prone (Superman-style) at speeds up to 125mph over the cavernous Penrhyn Quarry near Bethesda. The scale is breathtaking — the quarry is genuinely vast, the drop below you real, and the speed incomprehensible until you experience it. The whole package — the briefing, the walk to the launch platform, the view, the ride — is world-class.

Zip World Titan

Four people, four wires, racing side-by-side across a quarry. The most fun zip line in Wales.

If Velocity is the solo thrill, Titan is the group experience. Four parallel zip wires let you race side-by-side across the dramatic Llechwedd slate mine near Blaenau Ffestiniog. The course has multiple stages, each getting progressively bigger and faster. It's less about raw speed than Velocity and more about shared experience — screaming alongside friends while flying over quarry lakes. The mining heritage backdrop adds genuine atmosphere.

Zip World Fforest Coaster & Zip

The best zip line experience for families — forest setting, multiple activities, and accessible thrills.

Zip World Fforest near Betws-y-Coed is designed for families and those who want adventure without the extreme factor. The zip lines run through beautiful forest canopy, and the site includes the Fforest Coaster (an alpine-style toboggan run) and Treetop Nets. The whole package makes it a full-day family adventure. The zip lines themselves are fun rather than terrifying — perfect for kids and adults who are nervous about Velocity-level thrills.

Zip World Caverns

Zip lines UNDERGROUND. Fly through Britain's largest zip line cavern in the dark.

Zip World Caverns takes the zip line concept underground into the massive Llechwedd slate mines. Multiple zip lines, via ferrata bridges, and rope challenges run through illuminated caverns deep beneath the mountain. It's atmospheric, unusual, and unlike any other zip line experience in the world. The scale of the underground chambers is genuinely awe-inspiring. This is the most unique entry on the list.

Go Below Underground Adventures

Not just zip lines — a full underground adventure including the deepest zip line in the world.

Go Below operates in abandoned mines near Betws-y-Coed and offers a more hardcore underground adventure than Zip World Caverns. Their 'Ultimate Xtreme' trip includes what they claim is the deepest underground zip line in the world (1,300ft below the surface), plus abseiling, caving, via ferrata, and an underground boat ride. It's more physically demanding and more adventurous than the Zip World offerings — closer to caving meets zip-lining.

TreeTop Adventure (Betws-y-Coed)

High ropes and zip lines through forest canopy. The best tree-based adventure in North Wales.

TreeTop Adventure offers high ropes courses and zip lines through the forest canopy near Betws-y-Coed. It's not as fast or dramatic as the Zip World experiences, but the treetop setting is beautiful and the combination of climbing, balancing, and zipping makes it a more varied adventure. There are courses for different ages and abilities, from gentle junior courses to challenging adult routes with big zip finishes.

Zip World Tower (Hirael Bay, Bangor)

A new addition — zip from a tower on the coast with views across the Menai Strait.

Zip World's newest venture in Bangor offers zip lines from a purpose-built tower overlooking the Menai Strait and Anglesey. It's a shorter, more accessible experience than Velocity but the coastal setting is unique — you zip with sea views rather than quarry views. Being in Bangor makes it the most convenient zip line for anyone visiting Anglesey or the northern Snowdonia coast.
