You will have to step over a low chain link fence. The quarry is a couple hundred feet past the place where you parked. Much of the graffiti is from the 1980s and earlier, especially the marks on the cliff face itself. The 30-35 foot cliff on the opposite side of the quarry is the best spot to jump. There are many trails around the site for easy access to all locations.
