A challenging underground course, Caverns is a one-of-a-kind experience that takes up to 3 hours and will leave you exhilarated and drained in equal measure. Set in a historic slate mine, the various nooks, crannies, tunnels and chasms have been brought back to life with 13 zip lines, as well as via ferrata, rope bridges, tightropes and more, to push your bravery and endurance to the ultimate test.
It’s the perfect family day out in the heart of North Wales, with real teamwork and encouragement required to help each other round the course. It’s also a favourite amongst couples, as well as stag and hen parties – a truly unique activity that will provide a lifetime of memories.
Being completely underground, Caverns is an all-weather activity, making it a good plan for when the worst of the Welsh weather hits. It’s located at Zip World Slate Caverns in Blaenau Ffestioniog in the heart of Snowdonia National Park. If you’re not quite up to the challenge, Bounce Below is right next door, where you can let loose and have fun in the same stunning setting on our bouncy trampoline-style nets.
