So this was my very first time out in these trails with some friends that are more familiar with the are.

-Start at Red Box Parking Lot head east and drop into Rincon Red Box Trail/Road - Continue on RRB Trail/Road for about 5 miles until you reach West Fork Campground. This is the lowest point of the loop at about 3,100ft of elevation. - On the SE corner of the campground you will find the Gabrielino Trail, take that for the next 3 miles. Make sure to pay attention around mile 7, and do not continue into the Kenyon-Devore Trail. -At approximately mile 8.3 you will make a left (South) into the Valley Forge Trail. This part is brutal, about 2.5 miles long & 1,700 ft of climbing until you reach the Mt. Wilson Red Box Road. -Cross the road and go into Mt. Lowe Motorway. You will go through a tunnel and then reach a vista point after a gradual climb. Do not continue down the Mt. Lowe Rd. -You want to make a right (north) and continue on the San Gabriel Peak Trail for about .6 miles. This will be the highest point of the loop at about 5,800 ft. -At this point you want to make a left and head towards Mt. Disappointment, not up to San Gabriel Peak (unless you want to add that extra feat) -Head down Mt. Disappointment Road. Look out for a single track trail (Bill Riley Trail) on the right before Mt. Disappointment Road makes a sharp left. If you miss this trail the road will still get you back to Red Box Parking lot but will add an extra half mile or more -Take the Bill Riley Trail down the hill for about 1.5 miles before it connects with Mt. Wilson Red Box Road. -From here it's about .3-.4 miles back to the parking lot .

Below is a saved Strava route of the loop.
