Sitting along the eastern shore of Carlyle Lake — Illinois’ largest man-made lake — Eldon Hazlet State Recreation Area offers 3,000 acres of rolling terrain, open water access, and some of the best outdoor recreation in Clinton County.

The park’s main draw is Carlyle Lake itself. Boaters, anglers, and water-sports enthusiasts flock here for walleye, crappie, largemouth bass, and catfish fishing, while the lake’s size makes it one of the few spots in southern Illinois where sailing is genuinely rewarding. A full-service marina with boat rentals and launch ramps makes getting on the water straightforward, even for visitors without their own gear.

On land, miles of trails wind through prairies and wooded bluffs that come alive with wildflowers in spring and migrating waterfowl in fall. Birdwatchers regularly spot bald eagles along the shoreline during winter months, making Eldon Hazlet a year-round destination.

The campground is a strong suit here. Class A electric sites sit close to the lake with enough tree cover for shade, and the park includes a shower building and dump station. Reservations are recommended for summer weekends and holiday stretches — sites fill fast once temperatures climb.

Late spring through early fall is prime season for water activities, but autumn brings smaller crowds, cooler air, and stunning color along the bluffs. Winter eagle-watching draws a dedicated following as well.

With a 4.5-star rating across 154 reviews, Eldon Hazlet consistently delivers for families, anglers, and anyone looking to slow down near the water.
