Enter into an underground world as you gaze upon the world’s largest fully underground zip line and adventure course!
You’ll be tackling rope bridges, battling obstacles and riding on zip lines all the while being completely underground. These Caverns in Snowdonia have been inaccessible for nearly 200 years, which makes this adventure even more exciting.
There’ll be safety instructors who’ll kit you up and show you the ropes (literally!) in this underground world. First you’ll be taken through a training course before you are let loose onto the main spectacle.
This is the perfect way to bring your whole group together for your birthday, hen or stag do in Snowdonia.
And last but by certainly no means least, you’ll get the chance to experience the longest zip line in Europe!
This whole experience can last up to three amazing fun-filled hours so get your group ready for the adventure of a lifetime with Caverns in Snowdonia.
