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

The Orca activity in North Wales is an exhilarating afternoon of white water experience on guaranteed white water rapids. Starting the day in 7 man rafts to become familiar with the river and learn the techniques of craft control, you progress to the 2 man Orcas (above) which you have total control. North Wales has some of the best rafting in the UK and this dam controlled river guarantees a superb activity.
