The Valley used to be one giant off-roading mecca — just look at those old jeep-trail scars running up the sides of South Mountain. Driving has been banned from most of the mountain areas by now, and most of the 4x4 roads in and around Phoenix have been transformed into neighborhoods. But plenty of places remain where you can "tear it up," so to speak, with an ATV, dirt bike, or four-wheel-drive vehicle. (Please, be kind to the remaining desert flora!) There's no better place to romp than at Sycamore Creek, an area north of Fountain Hills that still welcomes off-roading. It's no place for environmentalists: Here you'll see all manner of rock-hoppers plowing through the water and grinding on the creek banks, racing up dusty hills and digging craters with their tires in the sand. It's not politically correct, but it's a hell of a lot of fun. Heading north on the Beeline, look for the turnoff left (west) onto 403. It helps if you bring a friend with another off-roading vehicle and tow straps, just in case.
