Although I said that hiking in summer can be dangerous, in the north too, but it's still doable. You must follow a very simple rule: "Carry enough water"
Ultra ordox kids are encouraged to hike the land, and summer is the only time they can do it. But they are not getting proper training about simple rules of hiking.
The section from Kinneret to Meron is in the north but those kids are not aware of the dangers going in Nahal (wadi) Amud.
It's a relatively long stretch with a short hike above a gorge, some 30 meters high. If one is dehydrated and loses concentration for a second, slips
and end of hike.... that's why kids die hiking the INT.
We have every summer at least 2-3 fatalities of ultra ortodox kids and occasionally tourists too, who don't follow basic rules.
