Formally known as the Kal-Haven Trail Sesquicentennial State Park, it runs 
33.5 miles (55 km) between South Haven, Michigan, to a point just west of the city of Kalamazoo, Michigan, where there is a trailhead. In 2008 the trail was extended to downtown Kalamazoo.The Kal-Haven is a rail trail, as it runs along the former route of the Kalamazoo and South Haven Railroad, as does that section of the River Valley trail. It traverses wooded areas, farmland and through small towns. It's primarily used by hikers and bicyclists in the summer and snowmobilers in the winter. The trail is surfaced, though not blacktopped. There are about seven miles of parallel trail in the western portion used by horse trail riding enthusiasts.
