If your planning a trip, include a stop at the Bar Ten Ranch (1Z1). Call ahead it gets booked during rafting season. It is the mid point out for rafters. They helio them from the bottom of the canyon, then they spend the night and then fly out to Vegas the next day.
No fuel so plan accordingly.
Rode my dirt bike in their a few years back. This is an amazing working Ranch, and they really take care of their guests. Top Notch service.
There are several rooms in side the lodge or you can sleep in one of their covered wagons.
Early Spring or Late fall is the best time to go.
