assuming you meant feet because 5 meters is about 16 feet. Heck 5 feet into rough ground can slip to a bad injury or death and that's nto even considering these are young girls slightly over a meter tall.
Sure, it looks fine until you realize there were rocks all around. One slip-up on the landing and hitting your head onto a rock can cause irreparable damage or even mortality. Especially the rocks could be extremely slippery since there could be moss growing on them.
