In the agency’s own words

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. Keep reading

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.

Facilities

Boulder Campground offers 82 campsites, all of which have a view of the lake with some sites being perched directly on the shoreline. Each campsite is equipped with electric hookups and provides a picnic area with picnic table and fire pit. The campground has modern amenities such as flush toilets, showers and drinking water. It is adjacent to the Boulder Day Use Area which provides a boat ramp and fish cleaning station, as well as a reservable group picnic shelter.

Natural Features

Created in 1967, the 26,000-acre lake is recognized as one of the nation's top ten inland sailing lakes and hosts several annual races and regattas. Carlyle Lake is home to an array of wildlife that can be seen throughout the year. Its waters and shores are a resting spot for migratory waterfowl and other birds. There are six established Watchable Wildlife Sites with viewing towers open to the public around the lake.

Nearby Attractions

The Carlyle Lake Visitor Center, located in the Dam West Recreation Area, has information available as well as nature exhibits on display, including a 215-gallon aquarium with native fish.

Who keeps the booking fee

The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

How we know

every fact on this page, and where it came from
Right now: U.S. Army Corps of Engineers publishes no season and no closure for this campground, and it takes no bookings we can read. That’s a gap in the record and not a locked gate: the number below is the only way to be sure.
Cell signal: the Army Corps’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
