Description

This is an easy, wide, dirt road that wanders up the center of Telegraph Canyon. Eventually, it leads to Four Corners and beyond. I've never been past Four Corners, so I can't describe it beyond there, but the elevation profile shows it dropping pretty quickly, which is why I gave it green/blue difficulty. If anyone can add to this description, please use the "improve this trail" section.

West from the campground to Four Corners is a brutal climb with no shade. Nothing technical. Just a steep grade.
