Quail Hill offers a few hiking, biking, and horse riding options from the Quail Hill Trailhead and Staging Area. The Trailhead is located on Shady Canyon Drive, just past Fossil Road on the right. To get there from the 405, take the Sand Canyon / Shady Canyon exit towards Shady Canyon Drive. Enter the traffic circle and take the first exit to the right onto Shady Canyon Drive. Turn into the first driveway on your right past Fossil.
I like the Quail Hill Loop for a few reasons, not the least of which is that it offers better views than you’ll find walking, jogging, or running around a high school athletic field.
