About the trail

The Cuyuna Lakes State Trail is eight miles of paved trail within the Cuyuna Country State Recreation Area from Crosby to Riverton. Abandoned by mining companies more than 35 years ago, the state recreation area contains six natural lakes, plus an additional 15 deep lakes that were former mine pits.
