For those who think central Illinois is one big corn field, Sand Ridge State Forest will come as a pleasant surprise. The forest is an island in a sea of agriculture. Just minutes southwest of Peoria, this 7,200-acre forest, the largest of Illinois' state forests, boasts sweeping expanses of native oak-hickory woodland, extensive pine plantations, sprawling open fields, grasslands and completely unique sand prairies. For a refreshing, invigorating taste of unspoiled nature and an opportunity to experience truly unique environment, Sand Ridge State Forest is ideal.
