Take a weekend camping trip to the Prescott area. There's a campsite at the top of Mingus Mountain, about 20-30 miles from Prescott. To get there from Prescott, take HWY 89 about 5 miles north and turn right onto HWY 89A. Take 89A to the top of Mingus Moutain, passing the back side of Prescott Valley along the way. Once you come to the top of the Mountain, you'll see a road off to your right. Once you get towards the end of the road, the road will fork, so take the left fork, past the lookout area and up the steep road. If you're not sure of my Directions, ask the people of the Bikesmith Cycle and Fitness about where the hangliders jump off the back side of Mingus Mountain. You'll be starting the trail-ride about 500 feet to the left of the hang-glider launch-pad. Anywhere along the rim, you can find picnic spots to spend the night, or make your own spot. Try to keep the area clean though. Once ready to ride, make sure you have extra tubes and a way to pump em up. Take the trail along the rim of the mountain, from the hang-glider launch pad to the west. Once you get to the crest of the rim, the trail veers off to the left sharply. take it to the bottom, where you'll find the trail turns into a road, and you'll see a large oak tree, with a natural spring, to fill up your bottles. Take the road due west and use the HWY 89A to come back up to the top of the mountain, then follow the road you drove up to get back to your camp. There are many trails along the back side of the mountain, so take a compass. YOU CAN GET LOST.
Summary: I ride this one every chance I get. It's a rough ride, but great for a work-out or a practice. It takes about 4 hours total, including spills and thrills. There are hikers up the trail occasionally, don't ask me where they come from...(!), but most of the time there isn't anyone but you and your buddies. Don't go alone. Some single-track is rollercoaster-like, and sometimes you just want to stop and pull in the awesome views of Sadona.
Recommended Route: counter-clockwise, from the top to the bottom (along the bowl,) and then back up along HWY 89A to get back to your campsite.
Other recommended trails in the same area: Spruce Mountain, Definately a killer rollercoaster ride.
