Directions: South at Yosemite and Lincoln. Turn right on ridgegate, follow to the end to the parking lot. Porta-John, two picnic tables at trailhead, but no water.
Trail Information: Close to the city, and not paved (crushed gravel). Some mtn bikers and walkers, but relatively unpopulated. Wide path, 2.7 mile loop, add spurs to make it 3.9 mi.

Miscellaneous Information:: Great views of the city--take an out of state friend for a quick run here and they'll always remember it. Did I say great views already? And don't tell anybody else how close and nice it is ;-)
