Sure to satisfy the thrill seeker in you, our Go Below® Challenge presents you with a series of exciting obstacles on a subterranean journey that'll leave you buzzing for more!


Normally our Go Below Challenge Trip runs from our Conwy Falls base, just outside Betws-y-coed. From Friday 2nd October and until further notice, The Go Below Challenge Trip will run from our Tan-y-Grisiau base in Blaenau Ffestiniog, Gwynedd. This is due to new Covid-19 travel restrictions placed on visiting Conwy County.

The Go Below Challenge Trip instead takes place in Cwmorthin Slate Mine and is broadly comparable in terms of length, difficulty and features, and is still suitable for anybody in a reasonable state of fitness from age 10 and upwards. Please speak to the office on 01690 710108 for more information.

Starting from our base you'll be kitted up with a harness, helmet, lamp, Wellington boots and safety equipment before heading off to the mine. You'll enjoy some stunning scenery on the walk up before heading into the darkness...

On your underground journey through the mountain you'll encounter forgotten deep blue lakes, lofty caverns and ancient mining machinery lying abandoned in the darkness. You'll cross zip lines and traverses, climb rock faces and waterfalls, boat across water and abseil off ledges for that thrilling adrenaline rush that'll leave you feeling totally exhilarated! Should you also want to know about the mining industry and its history during your adventure, our knowledgeable guides will happily fill you in!

What's involved in the Go Below® Challenge trip?

Whatever the weather, all year round, the Go Below® Challenge is a guided half-day (approx 5 hours) experience intended for those looking for a unique adventure activity which is sporty, physical and fun. No experience is necessary and all safety equipment is provided. You won't have to squeeze through tight spaces and although you might get splashed, you won't be immersed in water - unless you want to be!

We welcome individuals, couples, families, friends and groups who feel they can apply a little agility on the trip and are up for getting good exercise! The more daring activities can be bypassed if you don't feel confident enough to try them. However we don't recommend the Go Below® Challenge for those who are very unfit, excessively overweight, pregnant, infirm or of a nervous disposition.

Minimum age for the Go Below Challenge trip is 10 years old. We request that children aged between 10 and 17 years are accompanied by a responsible adult of 18 years plus.
