Buffalo Rock State Park is an Illinois State Park. It is located on Dee Bennett Road. It is between Utica and Ottawa in LaSalle County. The park is located on a bluff which is adjacent to the Illinois River. It is approximately 298 acres.
This is a historical site. It was the home of the Illinois Indians in the 1600’s. It is thought that Buffalo Rock was a French military and trading post as well as a missionary site. More recently the site was used by a religious sect for meetings. It was also used for a tuberculosis sanitarium. From 1916–1928, the site was owned by the Crane Company of Chicago. They used it as as a sanitarium for sick employees and a vacation ground for its workers and their families. The Crane Company deeded the land to the state of Illinois in 1928. The terms of the transfer were that the site would be a permanent state park.
The park is known for its panoramic view of the Illinois Valley and River. There are also two buffaloes kept on the site.
