This is an absolute must-do when you're in Vegas. I had a great time from start to finish. I was picked up at the hotel promptly (I traveled solo) and off we went to the beautiful canyon. There were about nine people in our group. The bikes are a lot of fun. You can alternate between pedaling or motor power or both. This excursion combines getting a little exercise with STUNNING views of the canyon. I highly recommend for the entire family.
