11-year-old going bouldering for the first time: how high are they likely to climb?

[nonicknamemum]

My 11-year-old DS is due to go bouldering for the first time, at an indoor centre, as part of an organised group. I made the mistake of looking at the pictures on the centre's website which has terrifying shots of people climbing great heights without a harness. Am now fretting. Can anyone reassure me that they will put some sort of sensible limit on how high an 11-year-old beginner is allowed to climb?

They will be closely supervised, and bouldering rooms have very, very thick bouncy mats covering the entire floor space, so even anyone falling from the top holds would not be injured (my DCs have been climbing and bouldering since the age of 7 & 10, no real injuries yet).

What exexpat said. Huge crash pads every where. After all, the only way down is to jump off!

Thanks both for your reassurance!
