LA 21 is a 52 mile long highway from the North Shore of area of Lake Pontchartrain in St. Tammany Parish to Washington Parish and the Mississippi state line north of Angie. Beginning at LA 22, LA 21 overlaps with LA 1077 northward through the Madisonville street grid before branching northeast along a commercial and suburban corridor to Interstate 12 and the Tchefuncte River into Covington. Following 21st Avenue and Boston Street into Downtown Covington, LA 21 combines with U.S. 190 Business 1.3 miles east to the grade separated intersection with U.S. 190.

Resuming a northeasterly heading, LA 21 advances from Covington to Waldheim and the unincorporated community of Bush. The state highway expands to four lanes from LA 41 and Bush northward to Sun and Sullivan Drive at Bogalusa. Continuing beyond Bogalusa, LA 21 travels through the villages of Varnado and Angie, ending opposite Mississippi 35 north to U.S. 98 at Columbia.
