You can also book onto our Discover Bouldering course to learn how to boulder safely and make the most of what's on offer.
* Please note that the Bouldering Only Registration will not allow you to use the roped climbing areas or supervise novice climbers.
Top-rope and Lead Climbing
To do this activity unsupervised you must be able to:
Put on a harness
Tie in using a figure eight or bowline knot
Belay someone safely, using a belay device
If you don't know how to do this, you have two options:
Come with a friend as a Novice Climber. Your supervisor must be a registered Roped Climber at The Castle. You can complete the Novice Supervision Form online - both you and the Supervisor must complete the same form. You will only be able to climb under their supervision.
Or, book onto one of our Learn to Climb courses and you'll be handling the ropes in no time.
All unsupervised climbers must read our Conditions of Use and Rules. Read the forms carefully because we'll quiz you to make sure you’ve read them when you register!
Everyone wishing to climb in the centre must complete a registration form - either the Unsupervised Climber Registration or the Novice Supervision Form. There is no charge for this. You will need to complete a new form every three years to ensure that you have read our most up to date conditions of use and rules and that the details we hold for you are current. See Admission and Membership for prices.
You may not top-rope or lead if you have a bouldering only registration.
You can upgrade to a roped climbing registration for free at any time.
Registered adult (over 18) roped climbers may supervise up to two novice climbers. If you are planning on bringing a novice, please check our novice supervision page.
What to Bring
You don’t need much equipment to climb indoors. You can start bouldering with just a pair of rock climbing shoes. If you want to top-rope you'll also need a harness, belay device and a locking carabiner. Most climbers also have a chalk bag to keep their hands from slipping on the holds. You can hire all of this equipment from The Castle Shop. Helmets are also available to hire from the shop.

“I would like to thank you and your team for running a great climbing centre and hope it will continue to run well. Looks like you need to expand!” (Eirik)
Not from around here?
Climbers from abroad should be aware that we do not use in situ belay devices fixed to ground anchors. Top-ropes are provided on many of our routes but you are expected to be able to belay from your harness and provide your own belay device. You can hire non-locking belay devices, ground anchors, harnesses and climbing boots from The Castle Shop. Registration forms are also available in Spanish, French, German and Italian.
