About
Overview
Boulder Campground is situated on the eastern shore of Carlyle Lake, a prime getaway for city-dwellers and families. Located 50 miles east of St. Louis, the area offers the peaceful retreat of a small town combined with the grandeur of Illinois' largest manmade lake.
Recreation
Boulder Campground provides fun both on the water and on shore. Boat ramps and courtesy docks are provided, and the vast lake allows for plenty of water sports. Fishing is a popular pastime, and the lake offers year-round varieties of fish such as bluegill, crappie, channel catfish, flathead catfish, white bass, largemouth bass, freshwater drum, carp and walleye. There is an on-site playground and plenty of open space for children to play, as well as an amphitheater for educational programs. A multi-use biking and walking trail is located a short drive away at the dam.
