Halmi Preserve doesn't show up on Google maps, but if you look on openstreet maps, you can see the trails there. Trailhead is right next to parking.
*Be careful when parking! I placed these caches when the ground was muddy, and my car got stuck. Thankfully, we got it out, but please be careful during/after a rain.*
This used to be a Cache Quest 360 cache, but it is now just a letterbox. Stamp and stamp book are in the CC.
