Rt. 31
From Illinois and west take I 94 into Michigan
Continue I 94 East to I 196 to Holland/Grand Rapids (just north of Benton Harbor)
Take I 196 to Rt. 31 Holland Exit (a left hand exit)
North on Rt. 31 to Business 31, Washington St. North (also a left hand exit)
Within a block is a stoplight at a Mr. Muffler - turn left, follow a left hand curve and a right curve to head due west.
It's a straight shot almost to Lake Michigan at which time you enter Castle Park.  Once the road starts to curve you'll
know you're almost there
Turn right at the 4 Way stop in the park and drive right up the driveway - Welcome!
