To get there: from I-25 and University head east on University (toward A Mountain - it's the big rock sitting in the middle of the valley). After a few miles you will see a few radar towers on your right (this is the first trailhead) or you can continue east for anoth 1/2 mile or so and park at the next big pull out. The trail circumnavigates the mountain so it don't really matter which one you start at. The trail is a mix of rocky doubletrack and smooth singletrack with a few technical spots trown in. There are a few feeder trails heading south and west and also to the top. There is also a dirt road that heads to the top from the south side of the mountain. Tons of feeder doubletrack heads east for the east side and supposedly hooks in with the Sierra Vista trail - but we couldn't figure out how to link it. Me thinks we not too smart.
