First time climber?

Anyone can try climbing… It’s the perfect antidote to boring gym regimes for adults and a great way to prove to kids that exercise is actually very exciting! Big Rock is fun, friendly and an awesome experience for all ages and abilities – if you’re looking for a new exciting challenge then Big Rock is for you.

Humans have been climbing things to escape from wolves and other scary stuff for thousands of years so don’t let modern life suppress your natural instinct to climb. Conquer our high roped walls for an unbeatable sense of achievement. Or experience the freedom of climbing without using a rope in our low level bouldering arena. Have fun and get fit!

If you have never tried indoor climbing before, you will need to book onto one of our Taster Sessions or Intro Courses.

You must be an experienced climber age 18+ to climb at Big Rock unsupervised. Under 18? Please visit our U18 CLUBS section.

Designed, built and used by people that are passionate about climbing, Big Rock is the area’s largest indoor climbing centre with over 1250sqm of climbing. We welcome all climbers, no matter whether you are just starting out as an independent climber or pushing the big numbers.
