These trails are the best in Phoenix - if you can find them! The best way to get to these great mountain biking trails is to head East on Dynamite Road off of Scottsdale Road, then do a U-turn at the first available left-hand turn. Then, backtrack west until you see a transformer box on the right side of the road. Turn into the desert there and park behind the box. Then, follow the power lines into Mountain Biking Heaven! On cool weekends, you'll also see cars parked along the north side of Dynamite Road.
