Although when you arrive at the West Rim the instructions given are pretty vague, the trip to the bottom of the canyon was amazing! The bus driver told us to be back by 2:30, but the helicopter ride got us back at 3:30, something that was out of our control. Our driver was very rude to us and the others on our return, even after we explained that it was not our fault. This kind of spoiled it for us. That being said, the view from the helicopter was spectacular and the young male guide on the raft below was very nice and full of great information. We floated down the river in silence, which was the highlight, as it has to be seen to be believed. If there was better communication between the helicopter company and the bus company, this day would have been perfect. The fact that the bus driver was so rude to us put a dark cloud over the whole thing. Go for the view, and I hope your driver is nicer!!
