The Hollow's first Indian visitors named it "Sica," (pronounced she-cha) meaning evil or bad. Eerie Sioux legends recall mysterious happenings here. Along the Trail of the Spirits, you'll see gurgling reddish bogs, which Indians saw as the blood and flesh of their ancestors. Indian lore gives new meaning to Sica's streams, rustic bridges, waterfalls, and wildflowers. An interpretive guide is available to bring these legends to life.
Despite its disturbing historical reputation, Sica Hollow State Park is an appealing place today, especially for equestrians. Fifteen miles of marked trails guide horseback riders through 900 acres of woodland, and horse camp sites are offered. Within the park are fire grates, a picnic shelter, tie rails, vault toilets and drinking water.
Sica Hollow State Park has earned a nationwide reputation for its attractions. The Old River Warren and Coteau des Prairies are designated National Natural Landmarks. The Trail of the Spirits, a self-guided interpretive foot trail, was designated as a National Recreation Trail in 1971.
