The web is a great source for local adventure info, but we strongly recommend obtaining a guidebook and the pertinent topo map(s) associated with any self-guided adventure.
If your plan is to ask for detailed backcountry info from a Spa Agent or a Resort Concierge, you probably need a guide.
Please note that cell phones often do not work in the Arizona backcountry. For more info, consult these Outdoor Safety Tips from Central Arizona Mountain Rescue.
