Lake Hiddenwood State Park 5.0 (reviews)

Melting glaciers carved the valley of Hiddenwood Creek. Traditionally, this area was home for several American Indian tribes. In 1927, the Department of Game and Fish used a new technique called an earthen dam to make Lake Hiddenwood, one of the first artificial lakes in South Dakota.Lake Hiddenwood is situated in a small, wooded bowl and is hidden from the view of most travelers ... thus its name. This park features a quiet campground, fishing and historic picnic area.
