There are two free camping sites easily accessed from US-69 highway near Pleasanton, Kansas. The sites are located within the Marais des Cygne State Wildlife Area, not to be confused with the nearby National Wildlife Refuge (which does not offer camping).
The sites are about 5 miles west of US-69 at the Kansas Highway 52 exit. Both are along the banks of the Marais des Cygne river, popular with locals for fishing and canoeing. Each site is equipped with a picnic table and makeshift fire ring. No other amenities are available; no vault toilets, no water, and no trash dumpsters.
