About
Overview
Cossatot Reefs Campground sits along the lush banks of Gillham Lake in southwest Arkansas.
Nicknamed the "Bright Spot on the Cossatot," Gillham Lake is a recreational oasis for outdoor enthusiasts.
Recreation
Visitors enjoy the lake for its vast boating opportunities, and a boat ramp is provided for easy water access. The river can be canoed from a point below the dam to U.S. Highway 71 South, a distance of about 16 miles. For shorter canoe trips, there are access roads to the river at Mize Crossing and Ladd Bridge.
Anglers will find smallmouth, largemouth, and spotted bass, crappie, channel and flathead catfish and various species of sunfish in the river.
A short nature trail within the campground weaves through a quaint wooded section. In spring, the trail is painted with colorful redbud and dogwood blossoms.
Facilities
Cossatot Reefs offers 31 shady campsites, including a large group shelter. Hot showers, drinking water and flush toilets help create a comfortable camping experience.
Natural Features
Gillham Lake spans 1,370 surface acres and boasts 36 miles of shoreline. The lake stems from the Cossatot River, designated as a National Wild and Scenic River.

Is COSSATOT REEFS fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
