Boulder Day Use Campground is a day use only camp that is open from 8 a.m. to 10 p.m. and has a $3 day-use fee at boat ramps. It is located right along the shore of Carlyle Lake which is recognized as one of the nation's top ten inland sailing lakes. There is plenty of lake and shore activities available here including an amphitheater and a playground with lots of space for children to play. Fishing for white bass, bluegill, crappie, channel catfish, largemouth bass, freshwater drum, carp, flathead catfish, and walleye is something that visitors also enjoy. The group shelter is $30 per day.
