Wow, so it sounds like there's a bunch of you looking for directions to the Fossil Creek waterfall now. I did a little search in order to provide a link, but I could only find maps of an 8 mile hike in the area, with no information on the waterfall or how to get to it. That won't do.
Solved! Here's a quicky-map of the 1-mile trail from the parking lot to the waterfall, with driving directions from Phoenix/ Flagstaff or from Mesa/Gilbert. Click on the image of the map to download.
Please bring a real road map too -- and sunblock. Be safe & have fun!
