About Us

Go Below is an award-winning, family-owned business offering authentic underground adventures, whatever the weather.

Experience exciting half and full day underground trips through abandoned mines located in the Heart of Snowdonia. We have 4 unique adventures ranging in difficulty and thrill level. No experience necessary, no potholing or squeezing through small gaps.

Our Go Below Challenge trip (10+) is a 5-hour experience, journeying through a fascinating subterranean environment. You will encounter ancient artefacts, boat across forgotten deep blue lakes, climb rock faces, and abseil off ledges with the help of our highly experienced guides.

For those wanting to push themselves further, our Hero Xtreme trip (14+) is 6 hours of exploring the largest and deepest slate mine in the world! Test your physical and mental ability whilst navigating through exhilarating traverses, bridges and zip-lines, with a chance to take a break on our Xtreme picnic bench, which hangs off a huge cliff face!

For the optimum bucket-list adventure, push yourself to the limit on our 7-hour Ultimate Xtreme trip (18+). Whether you’re a regular adrenaline junkie or want to brave it and overcome your fears, our Ultimate Xtreme trip is a world class unique underground adventure  featuring challenging climbs including the 'corkscrew', multiple zip-lines, the world’s only underground free fall and the world’s longest and deepest underground zip ride: 'Goliath’.

For a mammoth 14-hour adventure, tackle 'Mine to Mountain' - The Ultimate Ascent. It's a true test of endurance and stamina taking you 1,375ft underground to the deepest accessible point in the UK and then ascending to the summit of Snowdon, the highest mountain in England and Wales, all in one epic day!

All our trips are personally led by experienced and passionate guides, who will keep you safe while encouraging you to embrace your thrill-seeking side. Our trip leaders will also show you a glimpse of the slate mine industry and its history through the historic artefacts which can be seen along the way in this untouched authentic environment. 

Just when you thought our underground trips couldn't be any more exciting, check out our latest award winning epic adventure: Deep Sleep, the deepest underground accommodation in the world!
