Cassville Bluffs State Natural Area

This 244-acre bluffland farm had served as a nature retreat for the Roe family for over 50 years.  Cassville Bluffs State Natural Area (CBSNA) was conserved through a joint effort by the Mississippi Valley Conservancy and the Wisconsin DNR.  MVC owns 190.6 acres and the Wisconsin DNR owns the remaining 53 acres (primarily the bluffland goat prairies and savannas along the River.)

CBSNA contains a variety of habitats including upland and lowland oak-hickory forest as well as the rare savannahs and goat prairies overlooking the Mississippi River. 

The property also is home to a falcon effigy mound with a 270-foot wingspan that was constructed by Native Americans roughly a thousand years ago.


Cassville Bluffs State Natural Area is located at the end of Sand Lake Lane about 2 miles south of Cassville, WI in western Grant County along the Mississippi River. Cassville can be reached from Hwy 81 from Lancaster, or by Hwy 133 from points north or south. From Cassville go southeast on Hwy 133. You will pass a sign that says “Potosi-18 miles." Two miles beyond that sign, turn right onto Sand Lake Lane. There is a large white building just before Sand Lake Lane. Follow Sand Lake Lane to its end. The Cassville Bluffs parking lot will be on your left. Park inside the gate if it is open. If parking lot is full please park on Sand Lake Lane, taking care not to block any of the residences nearby.
