Rugged wooded hills and valleys abundant with oak trees makes Nine Eagles one of southern Iowa's most scenic parks. The park has some trees which are more than 300 years old. Visitors enjoy six miles of bridle and four miles of hiking trails, swimming at the sandy beach, pleasant camping areas and shaded picnic spots with tables and fireplaces scattered throughout the 1,100-acre park. Plants native to the area flourish and provide excellent cover for birds and wildlife. White-tailed deer can be seen almost every morning and evening along the park roads.
Waterfowl are a common sight along the lakeshore.
The name Nine Eagles was inherited from the first post office in Decatur County, built in the area that is now the park. However, there is good reason to believe that the name came from a prominent early family in the area, the Spencers. Nine Eagles State Park was dedicated on June 22, 1952. Nearby Towns Lamoni is seven miles west on Highway 69. Davis City is five and a half miles northwest.
