We went on the 6.30 bus from Cabanaconde and Im glad we made it before the tours. The canyon setting was gorgeous, but as soon as the tours arrived, you were literally squished against one another. There had to be over 100 people on this little lookout! We only ended up seeing 2 condors (and although beautiful birds), people thought it neccesary to whistle and call to them instead on being peaceful. As is, there is less and less birds flying because of the noise! Im glad we did not have to stay for tour and could leave when we want, as some tours stayed for hours when the birds only come for 20min or so.
Its beautiful to see, but a shame its not more natural and less intimidating.
