As someone that would want this for their kids: Is there am equivalent in the United States? Perhaps through scouts, or another org?
In my experience it was somewhat less dramatic than described in the article (I wasn’t left alone more than a half hour hike from camp and the few times I did it I never let the “victims” out of sight). It seems like these teens from the article are expected to put in a good few hours hike before getting back to a certain location. It was still a similarly formative and fun experience for me, especially because I got to do it with a couple other kids my age.
