To one side of it are rows of luxury homes. To the other side lie rolling hills and shaded canyons, with views of taller mountains in the distance: a scene that, but for a few fences and antennas, probably looks similar to how it did one hundred years ago. The Weir Canyon Loop in Anaheim Hills offers a surprising amount of solitude, scenic variety and a good workout in the bargain.
From the corner of Overlook and Hidden Canyon, start hiking on the fire road (the single-track that heads uphill is also an option, for a shorter version of the loop). At a junction, bear left (the right fork heads into Santiago Oaks Regional Park). Take a hard left at a fence and head uphill. You pass by a sandstone formation known as Eye-Socket Rock, and begin to work your way around the western side of Weir Canyon. Before long, virtually all sights and sounds of the nearby suburbs are gone.
At about two miles, head right as the Deerweed Trail heads uphill (you can take it if you want to shorten the loop). You continue toward the northern end of Weir Canyon Park, turning around just before you reach a row of houses. During the winter months, you may notice snow-covered San Gorgonio in the distance.
On the return, you continue heading uphill, rejoining the Deerweed Trail. You reach a ridge where, given clear weather, you can see the ocean and most of the Orange County coastal plain. At 3.5 miles, you begin a descent, soon arriving at residential Avenida de Santiago. You can either complete the loop on these residential streets or follow a single-track that branches off to the left. It soon splits three ways. The left fork returns you to the eastern side of the loop, while the other two lead toward the trail head. The central fork is more adventurous, dropping steeply and then climbing to rejoin the right fork, which skirts the eastern wall of the canyon. After the trails hook up again, a short descent brings you back to your starting point.
