Take interstate 8 East from San Diego to Lake Jennings Rd. Go north 3 miles to El Monte Road and turn right. Proceed until you see a "No Camping/No Fires" sign on your left. That is the trailhead. You can park along the road there.
The route goes off the road through a riparian area. Some climbers have been kind enough to point the way up with blue painted arrows and occasional signs noting "summit" with an arrow. In case you don't find these, continue up the trail until you hit a junction. Turn right and head for the South Arete. This trail leads directly to and up the side. More blue arrows and "summit" signs greet you up the ridgeline.
You may consider rope for the descent of the more difficult Class 3 sections on the ridgeline, because they tend to be quite exposed.
If you have information about this route that doesn't pertain to any of the other sections, please add it here.
