I'm used to 8~10m jumps and I jumped from a ~13m cliff once. <br>The difference was insane. Anything flat against the surface was in huge pain (foot sole, elbow, under jaw) even with shoes and wetsuit (wetsuit that was ripped apart). my neck got hurt and was stuck for days and my ear-drum got damaged.<br>I don't know how anyone can jump from more than that.,(reply>), I’ve done 50 ft, and have 0 desire to ever go higher. My arm was barely off of my body, and it bruised my bicep. <br><br>25-30ft is the most fun in my opinion. Perfect trade off between safety and thrill,(reply>), I've frequently done (25-40ft) 8-12m cliff jumps.  It is a big difference! I once did what we estimated to be 70-75ft (22-23m) We could have been off in our measurement but I wouldn't suspect we were for more than 5-10ft (2-3m).  I had heavy sandals on and wore a ski-jacket / life vest. I rehearsed each step to run off the cliff for 30 minutes, I even threw a pebble off to see how long I'd be in the air (about 3 seconds!).  Even with the ski-jacket on, which prevented me from going too far under to hurt my ears, etc., I ended up much deeper than I anticipated.  (I usually let the jacket pull me up but I had to start swimming.) <br><br>All this to say, it was very stupid and I'd never do it again! It was a really bad idea! I certainly wouldn't try to do any flippy-fips!
