Take a walk (followed by a bushwhack) in the Bioreserve. Parking is available at the coordinates below. Note that hunting is allowed in season as well.
Decided to explore this trail a bit more today after finding the new letterbox hybrid which starts at the gate and noticed this was a rather popular ATV trail. Hid the cache a good distance off the trail to ensure you won't run into any problems with ATVs when you seek it out, as well as increase the terrain rating by a bit. Hope you enjoy.
