Governor Nelson State Park is a 422 acre day use park located at 5140 County Hwy M in Waunakee, Wisconsin.

In 1976, the process of acquiring land began and finally in November 1987, Governor Nelson State Park opened.

In June 1988, former Wisconsin Governor and Senator, Gaylord Nelson held a dedication ceremony. Among his many accomplishments, Gaylord Nelson created Earth Day in 1970. Since 1970, April 22 has been set aside for all people to think about and appreciate our natural world together.

Governor Nelson State Park pays tribute to and embodies the ideals held by our former governor. When the park opened for the enjoyment of all, it was decided to name the park after Governor Nelson who is a role model standing for Wisconsin and American environmental protection, appreciation, and preservation of natural spaces. The Friends of Governor Nelson State Park endeavor to honor and continue these guiding principles so that all may enjoy this beautiful natural treasure!
