Using the UK’s Largest Bouldering Centre Area

For under 14 years old the only way to climb in the main bouldering area is being supervised by a competent Adult. If you, as the adult, are not happy to supervise them in this way then please check out our kids club offering.

If you wish to be a supervising adult then you must first be registered at HarroWall (or any LCC London Centre) as a Bouldering Supervisor. If you are interested to become a Bouldering Supervisor you can:

  • Register at LCC London if not already a member. You also must register the under 18 prior to your visit to HarroWall.
  • Download the Supervisor Assessment and bring it with you on your next visit at the Centre, where a member of the team will check it and update your profile.
  • Book a private session with an Instructor, specifying this as your requirement


If you are between 14 and 17 years old, you can climb in our Centre unsupervised. To climb unsupervised in the Centre there is a strict procedure to follow.

You have to complete and pass an Unsupervised Junior Boulderer Assessment in addition to:

  • 14 & 15 year olds: Your parent or legal guardian must accompany you on your visit to receive a briefing.
  • 16 & 17 year olds: Do not require parental visit but we reserve the right to call parents to verify consent and your parent/legal guardian must have signed the unsupervised junior boulder assessment and registered yourself prior your visit at HarroWall.

In any case the UNDER 18 MUST be pre-registered by their parent/legal guardian through our online registration form before visiting the Centre.
