Indoor climbing for children: the formats and the fit

Bouldering, auto belay, top rope and clip and climb are four different activities with different supervision models. Which suits which child, and what to check.

The short answer

Indoor climbing for children comes in four broad formats and they are not interchangeable. Bouldering is unroped climbing at low height over deep matting. Auto belay uses a self retracting device so a child can climb alone. Top rope requires a trained belayer. Clip and climb is an auto belay format built around novelty walls. The supervision model differs in each, the standard covering artificial climbing structures is BS EN 12572, and the most useful question at reception is who is responsible for checking a child is attached correctly.

Climbing walls have become one of the standard answers to the problem of the eight year old who has outgrown soft play. They are also the format where parents are least likely to understand what they have booked, because four fairly different activities all get called climbing.

The four formats

Bouldering. Unroped climbing on walls of limited height, typically over deep matting. There is no equipment to fail because there is no equipment. The safety system is the height limit, the matting and the rule about not climbing above a certain point. It is the most accessible format and the one where falls are most frequent and least consequential.

Auto belay. A device fixed at the top of the wall pays out a line as the climber ascends and retracts it, lowering them at a controlled speed when they let go. It allows a child to climb a full height wall without a partner. The entire safety system is the attachment: the harness fitted correctly and the karabiner clipped and locked.

Top rope. A rope through an anchor at the top, with a person on the other end managing it. This is the format that needs a trained belayer, which is either a member of staff, an instructor, or you after being assessed by the centre. It is the most controlled format and the least casual.

Clip and climb. Auto belay applied to a set of novelty walls: a ladder of blocks, a leaning tower, a drop slide. Designed for turnover and for children who want the experience rather than the sport. The supervision model is the same as auto belay, and everything depends on who clips the child in.

Four formats, four supervision models

A working frame put together by this desk from published guidance and from the plain wording of the standards named on the page. It is not a survey, not a measurement and not drawn from any venue.

The attachment is the whole thing

On any roped format, the failure that matters is a climber who is not properly attached. Harness on the wrong way, buckle not doubled back where the design requires it, karabiner not locked, or the climber clipped to a gear loop rather than the belay loop.

Well run centres respond to this with a check discipline: a member of staff physically checks every child before they leave the ground, every time, including the third climb of the visit. The good ones do it visibly and out loud.

The question to ask at reception, and it is the single most informative question in this format, is who checks a child is attached correctly before each climb. If the answer is a member of staff, that is the model working. If the answer is that parents check their own children, ask what training you are given, and take it seriously.

The standard and what it covers

Artificial climbing structures are covered by BS EN 12572, which deals with the walls, the anchor points and the associated equipment. As with all equipment standards, it addresses the structure rather than the operation, and in climbing the operation is where nearly all the risk lives.

Auto belay devices, harnesses and karabiners are personal protective equipment with their own inspection and retirement regimes. A centre should be able to tell you that its devices are serviced to the manufacturer's schedule and that its harnesses are inspected and retired. It is a reasonable question and a competent centre answers it easily.

Age and the size problem

Climbing has an unusual constraint: harness fit. Small children do not have hips, which means a sit harness has nothing to sit on and can be slipped out of. The answer is a full body harness, and a centre that takes small children seriously will have them in a range of sizes.

If a centre offers roped climbing to four year olds using only adult style sit harnesses, that is a genuine gap rather than a technicality. Ask what harness a child of your child's size will be put in.

Bouldering has no such constraint, which is one reason it works well for younger children. What it does have is a landing problem: a small child falling awkwardly from two metres onto matting is still a fall, and the matting is designed for a controlled landing rather than a tumble from height.

Sessions, clubs and the difference

Most centres offer three things to children and they suit different aims.

A casual session on clip and climb or auto belay is an activity. It lasts an hour, it is fun, and nobody is teaching anything. That is a fine thing to buy and it is worth knowing that is what it is.

A coached session or holiday course puts an instructor with a small group. The child learns technique rather than simply pulling harder, and for a child who has taken to it this is where the format starts to develop them.

A club is a regular commitment with progression, usually with the same coach. It is the point at which climbing stops being a day out and becomes an activity, and it is generally much better value per hour than casual sessions.

Parents often buy the first when they want the second. If your child came out of a clip and climb session wanting to do it again, a coached session is usually the better next purchase.

Reasonable questions at a climbing centre
  • Who checks that a child is correctly attached, and does that happen before every climb?
  • What harnesses do you use for small children, and do you have full body harnesses?
  • How are your auto belay devices serviced, and to whose schedule?
  • How often are harnesses inspected and when are they retired?
  • Do you offer coached sessions or a club, and what is the group size?

What to do while they climb

Climbing is one of the few formats where the standard parental instinct, shouting encouragement and route advice, is actively counterproductive. Route reading is the skill, and a child being told where to put their foot is not learning it.

Watching quietly is more useful. So is resisting the urge to push a child to the top. Coming down from halfway is a decision, not a failure, and a child who is allowed to make that decision will generally go higher next time than one who was talked into it.

How to think about the format

Climbing is one of the best answers available for a child of eight and up, and bouldering works considerably younger. Choose on the check discipline, the harness range and whether coaching is available. If you can only ask one question, ask who checks the attachment before each climb, and listen carefully to the answer.

Questions parents actually ask

How young can a child start climbing?

Bouldering on a low wall works from around three, because there is no equipment to fit. Roped climbing is harder below about five, not because of ability but because harnesses are difficult to fit safely on a small body. Centres that take young children seriously will have full body harnesses in a range of sizes.

What is an auto belay and is it safe?

It is a device fixed at the top of a wall that pays out a line as the climber ascends and lowers them at a controlled speed when they let go. The devices themselves are engineered products with servicing schedules. The realistic failure point is a climber who is not attached correctly, which is why the check discipline at the centre is what you should be judging.

Can I belay my own child?

Only if the centre has assessed you. Most centres run a short competency check before allowing anyone to belay, and a centre that lets an unassessed adult belay a child has skipped the step that matters most.

Is clip and climb the same as climbing?

It uses the same attachment technology and it is a genuinely enjoyable activity, but it is built around novelty walls and turnover rather than technique. If your child has taken to it, a coached session is usually the better next step and generally better value.

Should I encourage my child to reach the top?

Coming down from halfway is a decision rather than a failure. Children who are allowed to make that decision generally go higher on subsequent visits than those who were talked into it, and pushing a nervous first timer to the top is the standard way to produce a child who does not want to come back.
