Here is some quite staggering footage taken from a walk through a valley in Southern Spain. Seemingly the pathway was built back in 1901 but as you can see it hasn't seen a good refurb in quite some time - probably 109 years or so. There is a rather flimsy cable you are able to attach yourself to save you if you fall however I don't think I'd trust this with my life (for what that's worth). I think this footage is a few years old but it puts the fear in God in you nonetheless. Now I'm no sufferer of vertigo but I don't think this is a yomp I'll be hurrying to tick off and will leave this to the adventurous climbers amongst you. Enjoy and let me know how you get on!
P.S. Don't forget your bicycle clips.
