Velocity Zip Line

You're strapped into a harness, looking down at the Gwynedd valleys below, and the ground suddenly becomes very far away. Velocity Zip Line is the kind of thing that sounds brilliant in theory and absolutely terrifying in practice - a proper adrenaline rush suspended above the North Welsh landscape near Bangor.

It's a straightforward proposition: you're hoisted up, clipped on, and sent flying across a wire. The ride itself doesn't take long - a few minutes of pure rush - but the view on the way down is genuinely something. On a clear day you get sight lines across the Snowdonia foothills. On a grey one, you're just staring into mist wondering why you paid for this.

Really, it's for the thrill-seekers and teenagers trying to prove something to their mates. Adults who like a bit of danger but don't want to commit to rock climbing will find it satisfying. Young kids will be too scared; older ones (if they meet the height requirements) might have the time of their lives. It's not something to build a holiday around, but if you're staying at one of the caravan parks nearby - Ogwen Bank is barely a mile away, Snowdon View and Llanberis parks sit within four miles - it's a decent addition to a day out.

Check opening hours and weight restrictions before you go. Prices aren't listed anywhere obvious, which suggests it's moderately expensive. Allow an hour including the walk-up and safety briefing. Worth it once. Not worth driving from Bangor just for.
