Be warned, this is not for the faint hearted! Journey deep into the heart of a Welsh mountain for an extreme adventure and experience a whole new world - all while taking on epic challenges. Meet a seasoned guide for a briefing, get kitted out, then embark on a jaw-dropping journey which involves exploring secret subterranean tracks, tackling tough traverses, crossing decaying ancient bridges, climbing unspoiled rock faces, abseiling, whizzing down the planet's longest and deepest underground zip line - and last but not least, braving the world's first underground freefall. Stand at the edge of the ledge and plummet into a 70 foot abyss, falling at unbelievable speeds. No need to panic, the brake is applied before you reach the ground!
