This canon the very tip of which we visited to see condors, is deeper at its far end than the Grand Canyon but reaching this bit is a long and arduous hike. The more touristy bit we visited is as you would expect, steep, rocky with a river tinkling away in the bottom of the valley. It is empty, remote and spectacular with mountain peaks in the background. When we were there it was quite busy as it is a popular spot for condor viewing and the tour buses congregate there. That’s said it was all quite manageable. We were very lucky and saw condor by the bucket load. High, swooping low, three young perching on a branch sticking out over the canyon. Periodically one would glide by over the crowds, for all the world looking like a deliberate fly-by arranged by the tourist ministry. But we spoke with others who had been there the day before and saw only one condor in the distance. We were lucky, that’s wildlife for you. While worth the time and money to go there.
