El Dorado is located in Union County
(of which it is the county seat) south of Camden
along Hwy 82, near Ouachita River, Louisiana boarder and the Moro Bay State Park.
El Dorado also serves Hwy 15, Hwy 335, Hwy 7 and US Hwy 167.
This community was named for the fabled Spanish City of Gold. El Dorado's history started in 1843 when adventurer Matthew F. Rainey opened a store and settled here. Since 1921, when the area boomed due to the discovery of oil, El Dorado and Union County has offered business a golden opportunity for success.
El Dorado is home to two publicly traded companies: Murphy Oil and Deltic Timber which are traded on the New York Stock Exchange.
Some of the finest hunting and camping areas in the nation are in El Dorado: woods, hills, and valleys brimming with deer, duck, squirrel, and game birds. The Felsenthal National Wildlife Refuge contains 65,000 acres where you can fish year round.
