There is a difference between L.A.’s two worst freeways. Interstate 405 (see “Getty View Trail”) is pretty bad all of the time, while state route 91, in Santiago Canyon between Anaheim Hills and Corona, is often passable, but sometimes, it can be a complete H-E-double hockey sticks. If you are stuck on the 91 freeway during one of those times, consider taking a break and grabbing a hike on the Weir Canyon loop.
From the parking area, follow the trail 0.1 miles (bear left at the fork, where another trail leads into Santiago Oaks Regional Park), and take a hard left at a fence, where the trail heads up a hill. There is a steep, but short climb, then a descent into the canyon. After winding around through sandstone formations on the left and the body of the canyon on the right, along with great views of the Santa Ana Mountains, a giant water tank comes into view at about 1.5 miles from the trail head. Shortly afterward, you reach the end of the canyon and begin an ascent alongside some houses. For the rest of the hike, you will not be far from civilization, although with some nice views to enjoy, it is easy to forget that you are in the middle of Anaheim Hills. You will pass closer to the water tank, and at just over 3 miles from the trail head, you will reach a hill top from where you can, visibility permitting, see Chino Hills and the ocean and almost everything in between. You will now enter the end of a cul-de-sac, Avenida de Santiago. Head down-hill to Hidden Canyon where you will take a left and walk .2 miles back to your starting point.
