Beaver Creek Valley State Park is a state park of Minnesota, United States, featuring a steep, narrow valley carved by East Beaver Creek. This spring-fed stream is a fishing destination for its native brook trout, and introduced brown trout. The heavily forested valley, up to 250 feet (76 m) deep in places, is a hidden natural oasis amidst the farmland of southeastern Minnesota. Located near the town of Caledonia, the park was developed in the 1930s by the Works Progress Administration. The parkland exhibits the highly stream-carved terrain characteristic of the Driftless Area.
