Take the exit for Battle Creek Road heading South. Take a left at the four way stop. Take another left at the next four way stop.
Parking is free as are the trails.
From beginner to Expert. The trails are mostly singletrack with there being two sections of trails split in half by battle creek road. The outer loop is close to 5 miles. Just take a right onto the paved trail and you'll find it on your left eventually. Also, you can opt to jump on the new X-C ski trail.
