What our customers say.

Great confidence booster for those teenagers who want to something physical but don’t want it to be a big deal. The instructors make it fun and social and show the kids the techniques and then let them have a go – giving each teen the right level of support and encouragement. My 13 year old was buzzing from the excitement of climbing and can’t wait to go again and she doesn’t generally do excitement.

My daughter and her five friends had the most wonderful party here. From the moment harnesses were put on the children were having fun. The instructor ensured all kids were involved and active. No standing around, every minute all the children were doing something. They were buzzing and I had one very happy birthday girl. Would highly recommend it to anyone.

I took a youth group I run for young people with learning difficulties to this climbing centre as part of our Summer Activity Programme and it was fantastic! Lots of different walls of varying heights and difficulty levels. The instructor we had was fantastic, he kept the kids engaged, took time to ensure everyone understood what they were doing, why they were doing it and how to do it as well as making sure it was fun throughout. The entrance and cafe staff were really helpful and the food was great.

We took 12 children for an exclusive CrazyClimb party including room hire afterwards for my daughters 8th birthday party and it was fantastic. They all loved it! The instructors were very professional and brilliant with the children. It kept their attention the whole time and they were all able to do it to their own ability and age! They were so exhausted afterwards that they sat in the room quietly and ate all their lunch! The perfect party!

Absolutely excellent day, would highly recommend. We bought the CrazyClimb package for 12 children aged from 5 to 11 and each and every one had a brilliant time climbing under the guidance of three instructors. They were captivated and challenged for the full hour and kept busy running from one to the next with no children sat waiting around for a turn (only by choice to catch their breath from all the excitement!). The mums were able to sit down and have a nice coffee in the cafe area while we waiting for the children who were no longer interested in us. We hired the room upstairs afterwards and were allowed to bring our own food in and decorate the room. It was a really lovely day and would highly recommend this to other parents!

What a fantastic place for all ages and abilities! Our 7 year old daughter just had her birthday party here with 5 of her friends. We used the CrazyClimb facilities for the first time and it was just brilliant for them. The instructor was very encouraging and patient with the kids. Not once did we fear for their safety but an enjoyable time was had by all. We will be back again and I would recommend Big Rock to all.
