Small plastic container hidden in a little opening in a thicket. Easily accessed from the horse trail--or even from Biola University, if you're a student there.
If you like geocaching experiences that involve a quick-and-simple foray into the middle of a tree thicket, well this might be just the cache for you.
This cache is best approached from the La Mirada boulevard sidewalk; it's just a few steps away from the concrete.
