The rest of the directions:
Near Cadillac, go north on M-115 to the Manistee River, approximately one-half mile past the village of Mesick, Michigan. Cross the Manistee River Bridge and proceed one-quarter mile to County Road 9 -- it's the first road past the bridge and is marked with a small green "N 9 RD" street sign on a pole. You'll pass a green "Interlochen" sign on the right shoulder about 50 yards before the intersection.
Turn right onto County Road 9, go up the hill, and proceed 7.4 miles to the stop sign which will be at County Line Road -- it's marked by a small green "W County Line" street sign, and you'll see a green "Interlochen" sign on the right side of the road just before the intersection. Turn left onto County Line Road and proceed exactly 1 mile to the first intersection, marked with a green "Karlin Road" street sign (Karlin Road is Grand Traverse County 137, which becomes Michigan 137 near Interlochen). Look for a green "Interlochen" sign on the right just before Karlin Road. Turn right onto Karlin Road and proceed 9.7 miles to the Interlochen Center for the Arts. The campus entrance is on the left, just past the Interlochen State Park.
If you get lost along the way, call the Interlochen switchboard (open 24 hours) for help at 231/276-7200.
