Term-time After School and Weekend Clubs for Kids

Next stop the Olympics…?

Is your child ready to take their climbing to the next level? Perhaps all the way to Olympics… Then NICAS might be for them!

NICAS stands for National Indoor Climbing Award Scheme and is a UK-wide scheme designed to promote climbing development through structured learning and accredited individual achievement.

NICAS sessions are aimed at children 7-11 & 11+ and are grouped into regular weekly sessions that run alongside local school terms.

This means that children (& parents) can continue to learn alongside their new climbing friends at the same time each week for multiple, and continuous, school terms!

Promotion starts two weeks before each school half-term and is heavily in-demand, with most sessions selling out.

While the kids climb…

Get involved!

Climbing’s not just for kids! There are plenty of ways you can get involved with the action at HarroWall during your visit.

Take part in sessions alongside your children (just add yourself as a participant when you book on), or even sign up for an Induction Plus for an introduction to the sport of bouldering.

By the end of the session you’ll have discovered a new sport and will be ready to take our Bouldering Supervisor Assessment, which will allow you to supervise up to two children during independent climbing in HarroWall.

HarroWall Café

If climbing sounds too much like hard work, we’ve got the answer. Put your order in at the kitchen, sit back, and enjoy a great view of the action in the while the children conquer the walls.

We serve great coffee, tasty treats, and freshly cooked food made to order onsite, with options for adults as well as post-climb food for the kids.
