The best indoor climbing around!

Big Rock is fun, friendly and an awesome experience for all ages and abilities – we’re confident that we offer the best indoor climbing around. You’ll find roped climbing walls up to 11m high, a huge bouldering arena, a dedicated kids’ climbing area and something that’s entirely off-the-wall – CrazyClimb featuring a series of wacky climbing challenges. Great fun for kids and the perfect antidote to boring gym regimes for adults! And we’re open 7 days a week all year round including all Bank Holidays (closed 24, 25, 26 December).


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 areas. Have fun and get fit!



Indoor climbing with a difference… You may have tried climbing before, but not like this! It’s fun, it’s wacky, it’s totally CRAZY! Tackle a wall covered with large purple blobs, race the clock on the speed climb, climb a wall covered in rotating steering wheels… we’ve got loads of different challenges to attempt and each one offers a completely different and completely crazy experience!
