Set right next to the Blaenau Ffestiniog North railway station and just a short drive away from the Snodowian mountain and Porthmadog, Tunnel Below offers an indoor caving experience for customers of all ages. Those keen on potholing but not really into the unpleasant cold and dirt can enjoy sessions featuring a winding, rising and bending cave. Groups can also opt to include infrared guns and enjoy a battle in the artificial cave.
