From the south, LA 306 begins at a small public boat launch and proceeds south a short distance. It then turns sharply to the northwest and travels alongside Bayou Gauche, passing a series of fishing camps and boat houses. After 2.5 miles (4.0 km), LA 306 curves to the north to follow a drainage canal and passes alongside a suburban neighborhood. It then intersects LA 632 (WPA Road), which heads west toward nearby Des Allemands. The two highways run concurrently for a short distance until LA 632 turns east onto Grand Bayou Road. LA 306 continues northward through a largely uninhabited area before intersecting US 90 in the small community of Paradis. LA 306 proceeds northwest for three blocks and terminates at LA 631 (Old Spanish Trail).
