Papago Park Area features 5 miles of hiking trails near Tempe, AZ.
To get to the trail head starting from Mill Ave & University:Take Mill North, over the lake. Keep on it until Priest Drive/Galvin Parkway. Take a right. Go on Galvin until McDowell. Take a right. Go until the corner of a Jaguar/Porche dealer and take it right onto College. (Dealership on right). Take that just over a mile. You'll see a stone sign for Canal Park. Take that. It's called Marigold. Park in the lot. Ride in the direction you were driving until you see trails on left. You could also go to the right and head for the big slick looking rocks. Those trails are much more tame, but still fun.
