wow this is really amazing

Holy Crap. I guess I didn't realize how much I dislike heights until I saw this- i was pretty nervous during the entire shoot.

WOW. One of the coolest vids i've seen. This guy has HUGE nuts. Thanks for posting Silentm; I sent the link on to my friends too. Crazy..

Thats Just Absolutely Crazy!!!!

when i first saw i had my "Oh Shit!" moments. it's reeeaaalllyyy an impressive walk

HOLLY CRAP.. i would do all that upto the point where there is NO path but a metal bar !! thats where i would turn back !

awesome! I need to go there some day. At first I thought, oh, just a walk with heights, whatever. Then he got to the first "balance beam" and I was quite amazed that he'd do that while filming. Shortly after I noticed the safety hook lines. I'm guessing the camera man used them, but I really couldn't tell. That's an awesome climb though. How he did that while calmly filming . . . wow

Crazy European hiking trails. ;-)

you can see him passing a dude using the safety line. imo the camera dude was not using it because he was really fast walking the whole stretch
