Bil C was our driver/guide on this tour. He was prompt, courteous, and informative. Once we were on the tour I was so glad we booked instead of driving ourselves because the driver needed to be fully focused and familiar with the hilly, curvy, narrow roads and not looking around enjoying the views. But as a passenger, I was able to look at everything and enjoy the ride with the bonus of great narration along the way. Experiencing Mike O'Callaghan... bridge and Hoover Dam up close and in person was amazing. It was easy to book and Sweetours provided a great day traveling to, at, and back from Hoover Dam.
