Under 18s are more than welcome at Rainbow Rocket.

This page explains all the steps Parents and Under 18s must complete before they can climb.

I am:

  • Under 8:  We find children aged 8 and up can engage and enjoy climbing at the centre. Be advised that the reach and height of the majority of climbs are not suited to children under 8.  Instead we recommend Clip and Climb, located around the corner from us.


  • Inexperienced or Under 14 - you must be directly supervised at all times by an assessed Adult Bouldering Supervisor.  Step 4 explains the level of experienced required before assessment.


  • Experienced 14-17 year old - you may climb unsupervised following successful completion of an assessment with a member of staff.  This must be booked in advance.


  • Experienced Adult Climber - follow steps 1 to 4 below.

Step 1: Watch our Induction Video

Step 2: Read our Conditions of Use and Rules

We have a few rules that all climbers must follow while at our centre.  Those with less than a years experience should also read the Bouldering Good Practice guide.

Step 3: Register online

Complete our short registration form online for free, or register at the centre. This is required for all Adults and Under 18s.

Step 4:

Adult Supervisors

Under 18 climbers can only climb under the direct supervision of an experienced adult who has completed the Bouldering Supervisor Assessment.  The bare minimum level of experience before attempting the assessment form is having done 5 indoor bouldering sessions.  We recommend that one of these is an induction session, booked with an Instructor.

A maximum of 2 Under 18s may be supervised by an Adult Supervisor.

This process is to ensure the safety of minors and all users of the climbing centre.

Adult Supervisor Assessment

It is a short questionnaire, followed by a feedback session. The supervisor should be comfortable climbing and be aware of their children's safety.

No booking is required.  However you may have to wait a short time for Duty Manager to be available to review your form.  We may need to observe while you supervise your junior.

Experienced 14-17 year old climbers

Climbers aged 14-17 may climb unsupervised following successful completion of an assessment with a member of staff.


Assessments must be booked in advance. They last around 20 minutes during which a Duty Manager will assess the climber's competency to boulder unsupervised. This involves a short questionnaire which can be filled out at the centre, and a short observation of the young climber on the wall by a member of staff.

The bare minimum level of experience before completing the assessment form is having done 5 indoor bouldering sessions.

There is a fee of £5 for the assessment per climber.

14-15 year old climbers: A parent / legal guardian must attend the assessment

16-17 year old climbers: Parents are not required to attend the assessment. We may call the parent / legal guardian to confirm their understanding / acceptance of the Conditions of Use and Rules.
