This is an all day tour in a 10 passenger van. The van was spacious with no more than two persons per seat. Lots of windows although most of the viewing is outside the van at view points etc. If you are going to be in a van all day, the quality of the driver is very important. Our driver, Kenny, was really, really excellent. Smooth, calm, no fuss in tedious driving conditions. I was so glad not to be driving. As a guide, Kenny was also excellent. First he takes you to canyon viewpoints that are not overrun by crowds, but just beautiful. Second he provides discussions about the geology of the canyon and also the flora and fauna. Nice handouts with good information about the canyon. Lunch and shopping at the Cameron Trading post was fine. Crowded attractions like the Lodge are avoided.
We had previously done the train trip from Williams and we much prefer the van trip. There is no way to get around a lot of driving to visit the canyon, but Canyon Dave Tours makes it a very enjoyable day.
