Flandrau State Park is a popular state park spreading over 1,000 scenic acres in southern Minnesota. Surrounded by the Big Cottonwood River, floodplain forests, oxbow marsh, and wide open grassland, the park is a hotspot for outdoorsy activities, including hiking and fishing in the summer and cross-country skiing in the winter.

Formerly known as Cottonwood River State Park after the river that runs through it, Flandrau was used as a German prisoner of war camp during World War II and has plenty of history and culture for campers to discover. The park was renamed in 1945 to honor Charles E. Flandrau who helped draft the first Minnesota Constitution.

Today, the old POW camp is used as a modern group center with eight cabins, a dining hall and restrooms. There are also three campgrounds offering great facilities for RV campers, including a fantastic sandy beach and pool area, a children’s playground, and various sports facilities from volleyball nets to horseshoe pits. Families, big groups and solo campers of all interests are accommodated at Flandrau State Park with eight miles of hiking trails to explore, educational naturalist programs, and over 60 species of birdlife to spot, from warblers to flycatchers.
