Venture into the unknown by setting out on a journey deep underground and experience a whole new world you never knew existed. Meet an intrepid adventure guide at Conwy Falls and soak in breathtaking local scenery at ground level, before kitting up ready to start an authentic underground expedition. Journey into the heart of a mountain and discover sights you’ve never seen before. Encounter deep blue lakes that time forgot, colossal caverns, dramatic waterfalls and abandoned mining gear from yesteryear – all while abseiling off ledges, climbing rock faces and waterfalls, braving traverses boating across water, and whizzing across zip lines – just like The Goonies! Can you both handle this unique subterranean challenge?
