This trail system asks for an honor system donation of $3 at the unmanned entrance. Parking and trail entrance is located near the gun range where Saddle Creek Park Rd becomes Morgan Combee Rd (follow the dirt road).
You're looking for a medium sized camo'd container, just off the main trail. Bring your own pen.
The Tenoroc trail system is around 3 miles or so and has some pretty hilly, slippery terrain in some spots. Be sure to bring your bug spray. Lots of mosquitoes out here.
