The chaperones follow the travel on the bombard. If the bombard is not at the spawn point (you journal map marker), move towards the hamlet and you should catch up with it and the crowd following it.

The bombard moves a little every time it is taunted by an appropriate emote. Enemies pop up every minute or so that need fending off. In Cörthas, we're talking R35 fire elementals, but this is also because you're dealing with a bombard king. It drops the rare ash that one needs far less of.

You CAN do this is an R1, but it relies on other higher-ranked players being present for it to work.

The reason people are going to Owl's Nest in the Eastern Lowlands is because Falcon's Nest in the Western Lowlands has a crowd of R40 mobs in the tunnel that need fending off on top of everything else. And in a swimsuit, that's not as easy. But it means that the event there is not over-crowded and, if you wanted a challenge as an R50, you may have just found one.
