If you've never experienced the sheer thrill of white water, now's your chance! We kit you out in a wetsuit, buoyancy aid and helmet, then run through the basic manoeuvres on dry land before launching onto the river. The course runs a kilometre and a half through swift rapids with names like Ski Run, Graveyard and Donkey's Kick. Talking of kicks, this trip kicks your average theme park white-knuckle ride straight into touch. This activity will last for 2-3 hours and will include 4 runs down the river.

If you think you're ready for the next level in underground challenge, our Challenge Xtreme adventure will be just what you're looking for. After a short walk up to the entrance with stunning views on all sides, we enter the labyrinth of over fifty miles of tunnel and over a thousand spectacular caverns carved by the Victorians though the very heart of a mountain.

The going gets tough quickly, and it stays tough. Our route takes us over many lofty traverses - balancing on old beams or pipes over breathtaking voids of [Caver crossing a zip line underground] darkness. We cross ancient timber bridges and abseil off hideous drops to sink deeper and deeper under the earth.

Ultimately we reach the very bottom accessible floor of the mine - 1,300 feet under the mountain. It is here that we are at the very deepest point that can be reached in Snowdonia
