A 37-mile paddle that earned a state designation

The same river that floated white pine to the sawmills now floats kayaks past them. The Cass River Water Trail starts upstream of Vassar, where M-46 crosses the water, and runs about 37.5 miles down through Vassar, Tuscola, Frankenmuth, and Bridgeport before ending at the Saginaw River. The state recognizes it as one of its designated Pure Michigan water trails — a short list of rivers signed, mapped, and stitched together with launch sites for exactly this kind of trip.

The stretch right below Vassar is the one paddlers talk about. It’s heavily wooded, with rocky shallows and small rapids and riffles — enough moving water to keep you paying attention, not enough to scare off someone with a little experience. Below Vassar the river settles down. The run from Vassar to Tuscola is rural and quiet, mostly trees with the odd farm field or house slipping by, and the section from Tuscola toward Frankenmuth widens out into easy water a beginner can handle.

What makes it a trail and not just a river is the spacing. Roughly 13 canoe and kayak launches sit along the route, so you can pick a two-hour float or string several together into a long day, leave a car at the takeout, and not have to fight your way back upstream. Local groups along the Cass spent years building those launches town by town to make the whole thing work as a connected route.

It’s water with a long memory. The Cass carried logs in the 1800s and, the story goes, even carried the county’s records by canoe during an early fight over the county seat. These days it mostly carries people out for an afternoon, drifting past the wooded banks where, every so often, the bottom turns to rock and the river speeds up just enough to remind you it’s alive.
