This is a walking path up El camino del ray, an infamous hiking path in Spain. The walk is intense and often mind-boggling and unfortunately set to adult top 40 spiritual techno (but somehow it works.) This is comparable to- but not nearly as bad as- the french crane-pull-up video we posted
Interesting note, that is the first thing I've ever posted here that was actually FWDed to me! All my bitching about worthless FWDs and this one and actually delivers.
