This is a nice area to slow down, have a little stroll and maybe see some horses? I never have. Ahead of you it's about a mile and half walk to English Springs Park, "the duck park" as my family used to call it. It's not really a nature trail, but it's a nice walk.
To the left is the Chino Hills community center with a nice walking path encircling it (and another cache (not mine).
You're looking for a black, magnetic nano cache, teeny tiny, so you'll need to bring your own pen.
Congratulations to (wraavr) and (webfoot) for FTF
