This trail was in great condition Saturday. The Fault Line trail was a skinny tunnel in between 8 foot tall walls of yellow mustard. Only saw 1 gopher snake. I did this trail counter clock wise up the South Ridge roller coaster to San Juan Hill. Then down to the barn next to the campground. Great views the whole way! Yellow flowers as far as the eye can see on every hillside. Very few lupines left and hardly any poppies right now. The halfway point is the Rolling M Ranch barn and cattle chute that has (some) shaded picnic tables and clean restrooms with flush toilets and running water. The water fountain is turned off right now, but you can fill up your bladders/bottles in the sink in the bathroom. Continued on past the historic windmill on the Upper Aliso Canyon Trail to the unmarked left turn onto the Faultline Trail. (don't miss it!) It briefly heads past a small creekbed and then climbs steeply up towards a windmill (a landmark that tells you this is the correct trail.) Continue for about a mile and a half on this skinny trail until you exit right onto the wider Raptor Ridge Trail. This heads over and down to the main junction in Telegraph Canyon. From the Four Corners junction you have lots of options if you are burnt out, out of water, or get a blister, etc. You can hike the steep but scenic Bovinian Delight Trail back up to the South Ridge. Or head up the steep trail to the North Ridge to Gilman Peak to complete this specific loop. Or do what I did because of my blisters, and stroll down Telegraph Canyon road and back up Easy Street to the car to shave off a couple miles and elevation gain/loss. Telegraph Canyon was actually a nice option since you I got a canyon experience with shade and oaks after hiking sunny ridgelines all day. 5 stars for this loop. Check the temps before heading out, as Chino/Yorba can be blazing hot.

Started @ 0630 with temp. on the 40’s. Lost about a mile when we made a wrong turn. Steep hills and no phone signals on certain areas and maybe easier going counterclockwise instead of clockwise. Beautiful rolling green hills and not too much traffic. Love it!

Great wide open trails, not overgrown at all. Multiple trails to choose from to add to your mileage or keep to a few miles. Be ready for some pretty steep hills, good for runners, hikers, and bikers, but pretty challenging for strollers. Most of the western trails have no shade, but some shading in the canyon on the east side.
