@hischeekiness About an hour or so into the session the instructors (who were all Scouters and permit holders) gave the Scouts a rest and three of our four leaders had a go, one at a time. So while one was climbing and a permit holder was belaying, there were five other adults (three of our leaders and two instructors) to watch over the Scouts. The church is now an open hall with the climbing wall at one end. The area for the wall has some barriers denoting the area. While not partaking in the activity all our leaders supervised behaviour/wellbeing from outside of the area.
