Location Information

Mille Lacs Kathio State Park

Mille Lacs Kathio State Park is in the Mille Lacs Landscape Region. The park is primarily a second-growth forest of aspen, birch, maple, oak, and other northern hardwoods. Wetlands are abundant in the eskers on which the park is located. A few isolated remnant stands of conifers provide diversity to the landscape and a hint of what the forest looked like a century ago. Additional information about the park can be found here.
