On the way up, stop into South Haven for lunch on the Idler riverboat. Thursday wont be too bad, as the Fudgies will start hitting on Friday.
Once you get past Benton Harbor/St.Joe, get on M89(Blue Star Memorial Hwy) and stay on it heading North.It's a nice ride through the dunes, untill you get to the Blue Star and phoenix Road stoplight..take a left. Next light will be Phoenix/Broadway so take a right and follow it around the curve to the bottom of the hill where you'll need to take a left if the drawbridge is down and don't have to wait. Head west untill you find a place to park, and walk west untill you see the signs.
Good chow, and good views of the river Basin and all the goings on.
After chow hit the Maritime Museum on the other side of the river, only takes an hour unless you get fascinated by one of the many displays, or take a ride on "Friends good will". The north beach is worth a cruise on the way out. Just do a loop of the beach, and keep following North shore drive that will get you back on Blue Star(M89).
Just keep an eyeball peeled for all the idiot fudgies in thier Minivans while driving in town, and the fudgie pedestrians that just randomly cross the roads for no apparent reason. It's like Disney world in thier mind. LOL!!
From there, stay on Blue star and head north. Saugatuck is a yuppie Boater mecca that got overrun by "Artists" and fruit loops, and worth a stop if you're into the art scene, or really expensive nick nacks...and antiques. It's a different sort of town but has some good chow and a bunch of artisan choclatiers.
Palazzos Gelatto(local guy) can be had at the bar behind the Ice cream stand, next to Coral Gables, and is worth the ride.
Fenn Valley Winery is a 20 Min ride east of Saugatuck, and they have tours if you're into that.
Stay on Blue star from there, and you'll end up in Holland.
Put your head on a swivel when passing through, and double so when tooling around in town.
Mind the Snakes and Gators as well as the Deer on Blue star, and enjoy the ride!
Stay safe!
