==Natural attractions==
[[Crystal Cave (Wisconsin)|Crystal Cave]] is about a mile southwest of Spring Valley. This privately held natural attraction, formed millions of years ago by ground water eroding the sandstone and dolomite that underlies the area, has been open to tourists since 1942. A local 16-year-old discovered an opening to the cave in 1881. It was excavated, developed and promoted to the public by an Eau Claire, Wisconsin amateur geologist and advertising man. Opening day drew 4,000 visitors. The owners have retained the flavor of the 1950s and enjoy sharing the site's geologic history with visitors.

Promoted as the Midwest's largest earthen dam, Eau Galle Dam and Recreation, northwest of town, was built by the [[United States Army Corps of Engineers|Army Corps of Engineers]] in 1965 to protect Spring Valley from the Eau Galle River's surging flood waters. A recreational area has grown up around the dam's reservoir, Lake George.
