Bouldering as it is called is a very popular form of climbing. <img src="/forums/images/graemlins/grin.gif" alt="" /> It develops strong climbing instincts and power but requires skill and strength to do well. <img src="/forums/images/graemlins/smile.gif" alt="" /> In other words, its real climbing and kinda dangerous, technically challenging, yet close to the ground. Since your boys are neither skilled, nor strong, they will fall and should be prepared for it. Boys are poor spotters.

Have a thick foam matt or two to land on so you don't break an ankle. The first rule is - hit the matt and the 2nd rule is - do not roll over onto your face and break it. <img src="/forums/images/graemlins/blush.gif" alt="" />

Anyway bouldering is something that should have some adult supervision. <img src="/forums/images/graemlins/smile.gif" alt="" />And of course if there is no way down, then its not a good rock to climb, but most rocks have one 3rd class side. So remember - even though the bouldering grades are different, that bouldering is still technically - soloing technical rock and probably should be done with a belay with Boy Scouts and the problem is setting an adequate anchor. <img src="/forums/images/graemlins/tongue.gif" alt="" />
