Brandt Farview Orchard Directions

Mapquest link to 304 S Herman Rd., Suttons Bay, MI  49682

The Location and Route

Head out M22 from Traverse City north to Revold Road about 13 miles north of Tom’s West Bay (M72 & M22 intersection) and turn left (west).  There’s a sign for Revold before you get there.  Revold ends at Center Road (County Road 633).  Turn right (North).  Travel about 2.3 miles to Herman Road where the reduced speed zone and the 25 MPH speed limit sign is.   Turn left on Herman Road and travel about 1.4 miles.  There is a farmer’s windmill on the left before the unmarked asphalt paved drive also on the left. Turn left on the drive marked 304 (Farview Orchards).  This is opposite the Crestwood road sign is (on the right).  Note for GPS units, it is 304 S Herman Rd, Suttons Bay, MI. Remember
the “S”. (Long: 85.67503 W, Lat: 44.97759 N)

Off road to the picnic spot

Follow the asphalt drive turning to the left at the two forks on it.  The road will end in a gravel road by the front of a brown house (The Brandt’s).  Bill Hathaway, who arranged the use of the grounds, will place markers for the rest of the drive, that will take you through a cherry orchard to the picnic and viewing spot.  Drive slowly, it’s a bumpy ride through the orchard.  It’s about a mile from Herman Road to the picnic spot.

At the bottom of the last hill there is a stop sign. Turn right onto M-22 then veer left over the bridge which goes between Big and Little Glen Lakes (The Narrows). Continue on M-22 for another 4-5 miles into Glen Arbor. You will then come to a T-intersection (Anderson’s IGA market is on your right). Turn right at this intersection and follow M-22 for almost 3 miles. You will make a left turn down Port Oneida Road. Leelanau Outdoor Center is a mile and half down this road.
