It seems appropriate for one of the largest campgrounds in the Illinois state park system to be located on the largest manmade lake in Illinois. Eldon Hazlet State Recreation Area is a 3,000-acre site on the western shore of Carlyle Lake, a Kaskaskia River impoundment. The site is located 3 miles north of Carlyle and 2 miles east of Illinois Route 127 in Clinton County.
Eldon Hazlet SRA attracts more than 800,000 visitors annually to camp, boat, fish, hunt, picnic, bird watch and to hike more than 9 miles of trails. Also popular are the sailboat regattas, held almost every summer weekend.
