HarroWall is primarily a bouldering centre with its main objective of encouraging people of all ages to experience the wonderful sport of climbing. The Centre has problems ranging from those for beginners through to the hardest problems in the country. It is currently the largest bouldering Centre in the UK and has a huge range of training and gym facilities aimed at the climber who wants to get fitter, stronger and better at the sport - it has been awarded the title of National Performance Centre (NPC). In addition to bouldering, the Centre offers the following:

Large auto-belay wall with 10 lines of 7 metres in length. This offers customers the chance to climb longer routes with the security and ease of an auto-belay for lowering back down to the ground;
Routing roof which provides climbing at a 60 degree overhanging angle up to 10 metres in length;
Largest indoor cave in Europe at 170 metres with multiple challenges of an underground and squeezing nature!
Krazy Kong facility which offers 12 highly accessible fun and whacky climbing challenges. It also contains The Death Slide and The Nearly-Death Slide to finish off the experience!
Hard Play Area containing a castle, with battlements, a fearsome, smoke-breathing dragon and a rope bridge and slide for 3-8 year olds. This is NOT a soft play facility but rather a junior introduction to climbing and caving in a fun environment with hard surfaces and structures.
Soft Play Area which is only small but can keep under 3’s happy whilst elder siblings enjoy the other facilities.
Cafe serving the very best in hot drinks, snacks, pizzas and paninis.
Climbing Shop with the very latest in footwear, clothes and equipment;
Large function room for parties and corporate groups;
Changing rooms and showers;
Free parking but this will fill quickly at busy times so we would encourage journeys by public transport, cycling or walking
