From 131 take exit 101, the Greenville exit east all the way into Greenville on M-57. Make a right heading South on Baldwin Street, go through the 4 way stop. You will go through the intersection of Baldwin and South Street. You'll see on the south west corner the tee pad for hole #4. At the bottom of the hill is the parking lot.
There are a few parking lots that you can park in, the main parking lot is on Baldwin Street at the bottom of the sledding hills. Hole #1 starts on the other side of the street (east side of Baldwin), head towards the Flat River Trail head sign on the paved path and then cut left up the hill on the dirt path to hole #1.
