The Sica Hollow State Park is the location of one of the eerie myths of Native Americans. According to Siuox legends, the Hollow was named ?Sica?, meaning evil, because of the mystifying occurrences in the area. One of these legends is about the Trail of Spirits where Indians interpreted the iron-red water of the swamps as the blood of their ancestors.

Today, the state park is considered as a National Landmark and the location of two National Natural Landmarks, namely the Coteau des Prairies and the Old River Warren. The Trail Of The Spirits was also nominated as a National Recreation Trail in 1971 since it was opened to the public as a self-guided interpretive hiking path where Native American legends are brought to life.

Visitors can enjoy many activities that the park offers year-round. These activities include picnics and hiking explorations that allow any visitor to marvel at the natural splendor of Sica Hollow?s rustic bridges, streams, waterfalls and flora. During winter, the trail transforms into a cross-country skiing venue.
