South Haven Side Ride Professional Review and Guide
"This is another ride made possible by the wonderful work of Michigan's Rails-to-Trails Conservancy and the Department of Natural Resources. The 34-mile path of crushed limestone is a jewel in the state park system's crown, according to the thousands of bikers, hikers, horseback riders, cross-country skiers, and snowmobilers who have enjoyed its vistas of woods, farms, grasslands, and wetlands. Land has already been purchased to extend the trail to the South Haven pier, but until then this ride begins at the current trail end, at the Black River and Blue Star Highway.
It's a great family ride if you take the trail and return on it-there is no street traffic, and a plethora of signs warn of stops and driveways. For the more adventurous, the second half of the ride continues off the trail into the heart of blueberry county. The packed, crushed limestone / slag is fast-going, but take care to avoid the edges of the trail, where occasionally there are piles of gravel that make for tricky and sloppy riding. Also, watch for the signs warning of stops and driveways. Things to see: Kal-Haven Trail Sesquicentennial Park, Black River, fields and farms."
