Not sure what Kloofing is? Picture this:
You are standing at a rock crevice, ready to launch yourself into the cold water meters below.  Whether or not you repress the urge to scream is up to you, but down is the only way forward!
It goes without saying that a Kloofing Adventure should be undertaken in the company of an experienced guide, but as long as you are reasonably fit and have a zest for an adventurous life, then Kloofing is for beginners and more intrepid adventurers alike.
